0111 <H2>3. Items for migration of the user code</H2>
0112
0113 Listed here is some relevant information on developments included in this
0114 release.
0115 Note that for all users a full re-installation of libraries (or a full
0116 re-compilation) and a re-compilation of user applications is required.

0121 <UL>
0122 <LI>Fixed spurious compilation warnings on gcc when LTO settings are enabled.</LI>
0123 <LI>Set default for GEANT4_INSTALL_PACKAGE_CACHE to be OFF.
0124     This file is highly unstable on macOS and Spack installs, causing
0125     problems for most users. Retain the ability to install this file if
0126     really wanted, but change the default to NOT install it; in
0127     general this will not change anything for users provided they have a
0128     reproducible build environment setup.</LI>
0129 <LI>Removed configuration/setup of no longer supported TiMemory profiling.</LI>

0135 <LI>The G4Accumulable class was renamed in G4AccValue including the related
0136     functions in G4AccumulableManager; the old class name is still available
0137     via using.</LI>
0138 <LI>The following G4AccumulableManager functions are deprecated (a warning
0139     will be issued in compilation if present in user code):

0162     G4RadioactiveDecay-6.1.2, G4PARTICLEXS-4.1</TT> are required and should be
0163     used.</LI>
0164 <LI>Since Geant4 version 11.2, the physics list QGSP_BERT_HP has a treatment
0165     of low energy (&lt; <TT>20 MeV</TT>) neutrons which is not the same as for
0166     the other HP-based reference physics list (FTFP_BERT_HP, QGSP_BIC_HP,
0167     Shielding, etc.).
0168     QGSP_BERT_HP is still under validation, therefore it is not recommended for
0169     physics studies, but users are welcome to try out and provide feedback.</LI>
0170 <LI>Renamed G4RadioactiveDecay to G4VRadioactiveDecay and G4Radioactivation
0171     to G4RadioactiveDecay. The header for G4Radioactivation is preserved to
0172     provide backwards compatibility.</LI>

0176 <B>Run</B>
0177 <UL>
0178 <LI>G4TaskRunManager now organises workers so that each divides its events
0179     evenly across N tasks, rather than one task that processes all events for
0180     the worker. This should have no observable effect, though applications
0181     using the TBB backend to share it with non-Geant4 tasks may see different
0182     overall task numbers and ordering. Event order and reproducibility are not
0183     affected.</LI>
0184 <LI>Tuned verbose levels to reduce printouts during event loop.</LI>
0185 <LI>Added protection in <TT>G4VPrimaryGenerator::SetParticlePosition()</TT> to
0186     avoid and warn for attempts to place vertex position outside or on surface
0187     of the world volume.</LI>
0188 <LI>Cleanly delete G4Event objects at the end of each run as long as the
0189     events are not requested to be kept for redrawing during the following
0190     <TT>Idle</TT> state. The kept events are deleted at the beginning of next
0191     run or at program termination.

0226 <H2>4. New Developments and Capabilities </H2>
0227
0228 <B>General</B>
0229 <UL>
0230 <LI>First full implementation of sub-event parallelism, with creation and
0231     processing of sub-events in workers, and merging of results back into
0232     events on the main thread. Added sub-event parallel mode as an option
0233     in G4RunManagerFactory and new UI command for allowing trajectory merging.</LI>

0241 <B>Geometry & Field</B>

0242 <UL>

0243 <LI>Added option for performing the geometry initialisation phase,

0244     i.e. creating the 'optimisation' voxels for navigation, in parallel mode.

0245     The user can enable this option by calling the method

0246     <TT>RequestParallelOptimisation(optimise, verbose)</TT> of

0247     G4GeometryManager.</LI>

0248 <LI>New revised and optimised implementation of G4GenericTrap shape.</LI>

0249 <LI>Improved/optimised implementation of <TT>GetCubicVolume()</TT> in Boolean

0250     solids.</LI>

0251 <LI>Added new G4FieldBuilder class to construct what is needed (to carry out

0252     the propagation) for a user-specified type (class) of a magnetic or

0253     electromagnetic field; added also new classes to hold the accuracy
0254     parameters for the propagation tracks in magnetic or EM fields.
0255     Instantiating G4FieldBuilder also creates a set of UI commands in the
0256     <TT>/field</TT> directory, for changing the default field integrator,
0257     equation of motion and the accuracy parameters.
0258     Note: the field class can be either user-defined or an existing type
0259     from the toolkit, such as G4QuadrupleMagField or G4UniformElectricField.</LI>

0283     pair production by high energy gamma in an oriented crystal.</LI>

0284 <LI>Simplified computation of cross-section maximum for discrete processes

0285     in G4EmUtility.</LI>

0286 <LI>Introduced new classes G4UnknownParticle and G4ChargedUnknownParticle,

0287     part of ATLAS and LHCb request to assign automatically ionisation and

0288     multiple scattering processes to charged primary particles with valid PDG

0289     code but not known to Geant4.</LI>

0290 <LI>Implemented production and decay of omega(780) and f2(1270) for pion

0291     projectile and implemented decay of unstable isomers of recoil nucleus

0292     if not a natural isotope.</LI>

0297 <LI><U>Geant4-DNA</U>

0298     <UL>

0299     <LI>New classes implementing general models for ions heavier than Helium:

0300         G4GeneralIonIonisationModel, G4DNAIonChargeIncreaseModel and

0301         G4DNAIonChargeDecreaseModel.</LI>

0302     <LI>New class focusing on generating multiple-ionised water ions and

0303         calculating scale parameters to compute cross-sections of each

0304         multiple-ionisation process: G4DNAMultipleIonisationManager.</LI>

0305     <LI>New process classes for multiple-ionisation: G4DNADoubleIonisation,

0306         G4DNATripleIonisation and G4DNAQuadrupleIonisation.</LI>

0307     <LI>New model classes related to multiple-ionisation:

0308         G4DNADoubleIonisationModel, G4DNATripleIonisationModel and

0309         G4DNAQuadrupleIonisationModel.</LI>

0310     <LI>In G4EmDNAPhysics, defining default maximum kinetic energy

0311         <TT>600 MeV</TT> instead of <TT>300 MeV</TT> in order to have standard

0312         ionisation and multiple scattering always defined for DNA physics

0313         configurations.</LI>

0316

0317 <B>Hadronic physics</B>

0318 <UL>

0319 <LI>The angular emission for 4-body and higher-body generation in the Bertini-like

0320     intranuclear cascade model BERT has been improved.

0321     This has a visible impact on the simulation of hadronic showers for most of the

0322     reference physics lists, including FTFP_BERT and QGSP_BERT.</li>

0323 <LI>First implementation of the optional NuDEX nuclear de-excitation hadronic model,

0324     which provides a detailed emission of gammas and internal conversion electrons

0325     from the de-excitation of nuclei.

0326     This model relies on the new, optional dataset G4NUDEXLIB-1.0, accessed through

0327     the G4NUDEXLIBDATA environmental variable.

0328     For the time being, NuDEX can be utilised only for neutron capture in the

0329     physics list QGSP_BERT_HP. To enable it, one needs to include the following

0330     C++ code line <TT>G4HadronicParameters::Instance()->SetEnableNUDEX(true);</TT>
0331     in the main program, before instantiating the physics list.</li>
0332 <LI>For low-energy (&lt; <TT>20 MeV</TT>) neutrons, introduced the optional
0333     treatment of the Unresolved Resonance Region (URR) via Probability
0334     Table (PT), relevant for precise simulations of nuclear reactor criticality
0335     and shielding applications.
0336     This special treatment can be activated on top of any reference physics list
0337     based on HP or HPT by using the new physics list constructor class
0338     G4URRNeutrons. There are two possible types of probability tables - NJOY and
0339     CALENDF - and the choice between them can be done via the C++ code line, e.g.
0340     <TT>G4HadronicParameters::Instance()->SetTypeTablePT("njoy")</TT>
0341     in the main program, before instantiating the physics list.
0342     This treatment, when activated, needs the new, optional dataset G4URRPT-1.1,
0343     accessed through the G4URRPTDATA environmental variable.</LI>
0344 <LI>New class G4InterfaceToXS, to compute inverse cross-section using
0345     G4PARTICLEXS cross-sections for neutrons and light ions.</LI>
0346 <LI>Optimised G4ChargeExchangeXS, switching computations from level of
0347     isotopes to level of elements and making the code running faster
0348     without loss of accuracy.</LI>
0349 <LI>Added "HPT" extension to support adding G4ThermalNeutrons to extensible
0350     physlist factory.</LI>
0351 <LI>In de-excitation hadronic model, improved algorithm for handling of broken
0352     levels in G4LevelReader.</LI>
0353 <LI>Updates to cross-section classes to rationalise initialisation of data
0354     in MT mode.</LI>
0355 </UL>
0356
0357 <B>Physics Lists</B>
0358 <UL>
0359 <LI>New physics list constructor class G4ChargedUnknownPhysics, to be used
0360     on top on any reference physics list, to assign ionisation and multiple
0361     scattering (as well as transportation) processes to exotic charged particles,
0362     i.e. primary charged particles with valid PDG code but not known to Geant4.</LI>
0363 <LI>Added three new variants of <TT>Shielding</TT> physics list in
0364     G4PhysListFactory: <TT>ShieldingLIQMD</TT>, <TT>ShieldingLIQMD_HP</TT> and
0365     <TT>ShieldingLIQMD_HPT</TT>. These variants use the model G4LightIonQMDReaction.
0366     Note that <TT>ShieldingLIQMD</TT> and <TT>ShieldingLIQMD_HP</TT> are the same:
0367     the latter is introduced for consistency.</LI>
0368 </UL>
0369
0370 <B>Visualization and Interfaces</B>
0371 <UL>
0372 <LI>Improved plotting with <TT>/vis/plot</TT> if TOOLS_USE_FREETYPE flag is set.
0373     Set GEANT4_USE_FREETYPE=ON in CMake.</LI>
0374 <LI>Improved identification of scene tree models in visualisation.
0375     Now suppressing the scene tree if the number of touchables exceeds
0376     10000 (equivalent to about 20 MB).</LI>
0377 </UL>
0378
0379 <B>Examples</B>
0380 <UL>
0381 <LI>Extended example RE03 in 'extended/runAndEvent', demonstrating the ability
0382     to run in sub-event parallel mode.</LI>
0383 <LI>Introduced 'exoticphysics/channeling' examples category, created 'ch0'
0384     example out of the original example and added 'ch1', 'ch2' and 'ch3'
0385     examples. ch1: an easy demonstration of the minimum requirements necessary
0386     to integrate the G4ChannelingFastSimModel and the G4BaierKatkov model into
0387     a project in order to simulate the physics of channeling and channeling
0388     radiation/coherent bremsstrahlung; ch2: an enhanced version of ch1,
0389     providing the user with the full functionality of both demonstrated models,
0390     with parameters set up via a macro; ch3: demonstrating the minimum
0391     requirements necessary to integrate the G4CoherentPairProduction process
0392     into a project, along with the demonstrated models, to simulate the physics
0393     of electromagnetic showers in an oriented crystal.</LI>
0394 <LI>Created a new dna category for Geant4-DNA advanced examples, including
0395     <TT>moleculardna</TT> example, moved from extended category and new
0396     <TT>cellularPhantom</TT> application, showing how to simulate the
0397     irradiation of a 3D voxel phantom containing biological cells, created

0416 <UL>
0417 <LI>Electromagnetic shower shapes will be affected on level of per mille
0418     if 3-gamma annihilation is enabled. For low energy positively charged
0419     particles the agreement of simulation versus data will be improved.</LI>

0422 <B>Hadronic physics</B>
0423 <UL>
0424 <LI>Due to the improvement in the angular emission of &gt;= 4 particles in the
0425     final-state of the BERT model, the hadronic showers for most of the reference
0426     physics lists, including FTFP_BERT and QGSP_BERT, have few per-cent higher
0427     energy response and narrower lateral shower shapes with respect to the
0428     previous version, Geant4 11.2.
0429     In other words, the hadronic string models (FTF and QGS) and the intranuclear
0430     cascade model BERT become closer to each other in this Geant4 release.</LI>
0431 <LI>The new hadronic dataset G4PhotonEvaporation-6.1 produces some visible differences
0432     in the final-state of the photo-evaporation model in Tungsten, with respect to
0433     the previous version.
0434     This has an impact, at the per-cent level, on hadronic showers in Tungsten
0435     calorimeters only for the physics lists QGSP_BIC and QGSP_INCLXX (whereas
0436     those that are based on BERT model, e.g. FTFP_BERT and QGSP_BERT, are not
0437     affected because BERT has its own internal nuclear de-excitation model that
0438     does not use the G4PhotonEvaporation-6.1 dataset).</LI>

0511         visualisation driver variables that are just synonyms for more
0512         fundamental config options (e.g. GEANT4_USE_QT) with the underlying
0513         variable.</LI>
0514     <LI>Simplified CMake/CTest functions and settings: moved <TT>geant4_add_test</TT>
0515         function to dedicated module, retiring <TT>UseGeant4_internal</TT> file;
0516         reduced oversetting of <TT>Geant4_DIR</TT> variable for use by tests.</LI>

1161         transition from given level to itself with zero transition energy is
1162         ignored. Added two counters for limitation of warning printouts.

1229         (NuDEX) as far as the emission of gammas and internal conversion

1231         G4NUDEXLIB-1.0, which is pointed by the environment variable
1232         G4NUDEXLIBDATA. When NuDEX is not applicable - e.g. because the
1233         corresponding nucleus is not present in the dataset - the
1234         G4PhotonEvaporation class is utilised instead. Currently, the model
1235         will be used only for the neutron capture process, when ParticleHP is
1236         utilised; in the future it can be used more generally as one of the

1390 <LI>Added new class, G4ChargedUnknownParticle, similar to G4UnknownParticle for

1391     charged unknown particles. Part of ATLAS and LHCb request to assign

1392     automatically ionisation and multiple scattering processes to charged

1393     primary particles with valid PDG code but not known to Geant4.</LI>

1394 <LI>Applied correction suggested in

1395     <A HREF="https://github.com/Geant4/geant4/pull/74">GitHub PR#74</A>,

1396     fixing G4ParticleMessenger never updating the currently selected particle.

1397     Simplified logic in patch to remove local static.</LI>

1549 <LI>Tuned verbose levels to reduce printouts during event loop.</LI>

1550 <LI>First full implementation of of sub-event parallelism, adding the

1551     creation and processing of sub-events in workers, plus the merging

1552     of results back into events on the main thread.

1553     No impact of the core changes needed to support sub-event parallelism in

1554     any other mode (Seq, MT, Tasking) other than some counting aspects with

1555     retained events.</LI>

1556 <LI>Set number of random numbers generated as the seeds of workers for

1557     sub-event level parallelism.</LI>

1558 <LI>Defined UI alias representing the run mode [sequential, eventParallel,

1559     subEventParallel]. This alias can be used in macro file.</LI>

1560 <LI>G4RunManagerFactory: added sub-event parallel mode as an option.</LI>

1561 <LI>G4RunMessenger: added a command for trajectory merging in sub-event

1562     parallel mode.</LI>

1563 <LI>G4SubEvtRunManager, G4WorkerRunManager, G4WorkerSubEvtRunManager: added an

1564     option to merge trajectories created by worker threads in sub-event parallel

1565     mode.</LI>

1566 <LI>Fix in G4WorkerTaskRunManager and G4TaskRunManager, to process only

1567     <TT>NumberOfEventsPerTask</TT>. Before this change, each thread would

1568     process all its events in a single task since

1569     <TT>GetNumberOfEventsToBeProcessed()</TT> returns the number of all events

1570     in the run. All other tasks would immediately return because no work is

1571     left.</LI>

1572 <LI>Fixed static memory leak of process and tracking managers in worker threads.</LI>

1573 <LI>Provide static initialization for <TT>masterWorlds</TT> in G4MTRunManager.

1574     Adapted G4SubEvtRunManager and G4TaskRunManager accordingly.</LI>

1575 <LI>G4RunManagerKernel, G4RunManager, G4SubEvtRunManager: cleanly delete G4Event

1576     objects at the end of each run as long as these events are not requested to

1577     be kept for redrawing during the following <TT>Idle</TT> state.

1578     The kept events are deleted at the beginning of next run or at program

1579     termination.</LI>

1580 <LI>G4Run: added <TT>GetNumberOfKeptEvents()</TT> method.</LI>

1581 <LI>Extended diagnostics and output from material scanner.</LI>

1585     function from G4FieldBuilder <TT>Reinitialize()</TT>.</LI>

1586 <LI>G4RunManagerKernel: removed call to <TT>ResetNavigator()</TT> during

1588     beginning of <TT>BeamOn()</TT>.</LI>

1589 <LI>G4PhysicsListHelper: added <TT>DNATripleIoni</TT> and

1590     <TT>DNAQuadrupleIoni</TT> for the implementation of multiple-ionisation

1591     processes in Geant4-DNA. Added XrayReflection (<TT>fGammaReflection</TT>).</LI>

1592 <LI>G4RunManager: added <TT>SetDefaultClassification()</TT> methods to enable

1593     setting the classification for tracks newly arriving to a stack.</LI>

1594 <LI>Access G4GeometryManager singleton through its <TT>GetInstance()</TT> call

1595     in G4RunManagerKernel and G4WorkerRunManager.</LI>

1596 <LI>Updated G4AdjointSimManager and G4AdjointSimMessenger to allow running

1597     adjoint simulation in MT mode.</LI>

1599 <LI>Fixed compilation warnings for implicit type conversions on macOS/XCode

1600     on G4MSSteppingAction. Use consistently G4 types.</LI>

1601 <LI>Fixed reported Coverity defects: in G4MSSteppingAction for restoring

1602     original stream format state; in G4RunManager and others, for use of

1603     <TT>std::move()</TT> and restructured conditionals. Also fixes in

1604     G4Task/SubEvtRunManager.</LI>

1614 <LI>G4Trajectory and G4TrajectoryPoint: added <TT>CloneForMaster()</TT> method

1615     for merging trajectories created by worker thread in sub-event parallel

1617     and G4ClonedTrajectoryPoint classes for clean and safe use of G4Allocator.

1646     <LI>Rationalisation, simplification and code tidying.

1647     <LI>Updated visualisation manager to correctly merge/handle asynchronous

1648         event merging (also resolving long standing issues with post

1649         processing). Implemented <TT>EventReadyForVis()</TT>, used by

1650         G4SubEvtRunManager; restructured EndOfEvent functions to accommodate

1651         this and avoid code duplication; this involved introducing:

1652         <TT>Relinquishable</TT>, <TT>EndOfEventKernel</TT> and

1656     <LI>Improved identification of scene tree models: use full description,

1657         including embedded blanks.</LI>

1658     <LI>G4VViewer: check validity of arguments in SceneTreeScene constructor.

1659         Pre-calculate quantities in SceneTreeScene constructor; pre-calculate

1660         the number of touchable; if more than 10000, suppress them in the

1661         scene tree and add some information about it to the model item so that

1662         it pops up as a tooltip in the GUI.

1663         More logical order of some functions.</LI>

1664     <LI>G4VSceneHandler: specify the G4PhysicalVolumeModel for construction

1665         of scene tree. Simplified loop over models, added some printing.

1666         Print number of touchable by depth (if verbosity &gt;= confirmations).

1667         Print problematic volumes (if verbosity &gt;= confirmations).

1668         In <TT>DrawEvent(), DrawEndOfRunModels()</TT>, check if viewer is

1669         <TT>ReadyToDraw()</TT> at begin of method.

1670         Moved some printing outside the loop over models.</LI>

1671     <LI>Limit the number of scene tree items. For complex geometries, the scene

1672         tree can take up a lot of space, and, anyway, not easy to navigate.

1673         Now suppressing the scene tree if the number of touchable exceeds

1674         10000 (equivalent to about <TT>20 MB</TT>).</LI>

1675     <LI>G4VisCommandsViewer: use <TT>GetSceneTree()</TT> rather than

1676         <TT>AccessSceneTree()</TT> when not necessary. Simplified use of view

1677         parameters of a pre-existing viewer; use the parameters of the most

1678         recent viewer whatever its type in <TT>/vis/viewer/create</TT>.

1679         Exclude GlobalMarkerScale from parameters copied from pre-existing

1680         viewer, thus each viewer is allowed to specify its own

1681         GlobalMarkerScale.</LI>

1682     <LI>In G4VisExecutive, trap use of run-time visualisation driver choice,

1683         and (if using run-time choice) insist the UI session is instantiated

1684         *before* G4VisExecutive.

1685         Keep <TT>argc, argv</TT> and user-specified system, if specified, for

1686         delayed use. Moved informational (G4warn) from G4VisManager.

1687         Removed duplicate instantiation of TOOLSSG_OFFSCREEN.

1688         Removed inclusion of QtGlobal header, no longer needed.</LI>

1689     <LI>Delay determination of the run-time-chosen default driver.

1690         The run-time-chosen default driver is not actually used until the first

1691         use of <TT>/vis/open</TT> or <TT>/vis/sceneHandler/create</TT> without

1692         driver parameter, so we delay to this point. This catches the situation

1693         when the user instantiates the UI session *after* instantiating the

1694         vis manager.</LI>

1695     <LI>G4VisManager: make <TT>GetDefaultGraphicsSystemName()</TT> virtual and

1696         non <TT>const</TT>.

1697         The code for choosing a default driver *has to be* in user space, i.e.,

1698         in G4VisExecutive, so that it has access to use flags. Modified the

1699         informational (G4warn) in <TT>PrintAvailableGraphicsSystems()</TT>

1700         to give advice and point to further information to be given after

1701         <TT>/vis/open</TT>.

1702         Protected <TT>Begin/EndOfRun()</TT> against invalid view (includes

1703         check on existence of a scene). Some tidying and streamlining.

1704         Introduced local Booleans <TT>isValidViewForRun</TT> and <TT>isFakeRun</TT>.

1705         Introduced <TT>PrintAvailableVerbosity()</TT>.

1706         In <TT>GetVerbosityValue()</TT>, print verbosity options on unknown

1707         or empty argument. Call <TT>PostProcessingFinished()</TT> for _every_

1708         event in <TT>EndOfEventCleanup()</TT>.

1709         Fixed "accumulate" bug in Serial mode, and other small improvements.

1710         Improved printing of colours in <TT>PrintAvailableColours()</TT> and

1711         advise on use. Rationalised code and tyding.

1712         Protect <TT>KeepForPostProcessing()</TT> mutex lock;

1713         <TT>KeepForPostProcessing()</TT> is called on a worker thread,

1714         <TT>PostProcessingFinished()</TT> is called on the vis sub-thread,

1715         so should be protected.</LI>

1716     <LI>G4VisManager, G4VisCommandsSceneAdd: optimised timing of G4Event for

1717         <TT>KeepForPostProcessing()</TT> and <TT>PostProcessingFinished()</TT>

1718         so that event object that are not requested to be kept are cleanly

1719         deleted at the end of each run. Kept events are deleted at the

1720         beginning of the next run or when the program terminates.

1721         Use <TT>GetNumberOfKeptEvent()</TT> from G4Run to properly display

1722         the number of kept events.</LI>

1723     <LI>G4VisCommandsTouchable: <TT>/vis/touchable/dump</TT> and <TT>findPath</TT>

1724         do not need a scene handler nor a viewer.

1725         Moved them to the beginning of <TT>SetNewValue()</TT> in

1726         G4VisCommandsTouchable, before the check on scene handler and viewer.

1727         This allows the user to <TT>/vis/touchable/dump</TT> even if not yet

1728         opened a viewer.</LI>

1729     <LI>G4VisCommands: in <TT>/vis/list</TT>, added printing of verbosity

1730         options. In <TT>/vis/verbose</TT>, changed default value to empty

1731         string.</LI>

1732     <LI>G4VisCommandsSceneAdd: date and time are updated for every event

1733         displayed. Ensure the logo respects the current requested

1734         number of sides per circle in <TT>/vis/scene/add/logo</TT>.</LI>

1735     <LI>G4VViewer: added virtual <TT>ReadyToDraw()</TT>, helps avoiding a

1736         crash on macOS if doing <TT>/run/beamOn</TT> in vis.mac at startup.</LI>

1737     <LI>G4ViewParameters: minor improvements to messages in output

1738         <TT>operator<<()</TT>.</LI>

1739     <LI>Introduced TOOLS_USE_FREETYPE flag in vis management for <TT>/vis/plot</TT>

1740         UI command. In G4VisCommandsCompound, if TOOLS_USE_FREETYPE is set,

1741         augment <TT>/vis/plot</TT> UI command to take <TT>style</TT> argument.</LI>

1742     <LI>Removed use of G4MULTITHREADED symbol where not required, using
