0120 <H2>3. Items for migration of the user code</H2>
0121
0122 Listed here is some relevant information on developments included in this
0123 release, some of which may require migrations (mainly for users of advanced
0124 Geant4 features) in order to upgrade from release 9.2 to release 9.3.
0125 Note that for all users a full re-installation of libraries (or a full
0126 recompilation) and a recompilation of user applications is required.

0132 <LI>A new method <TT>CheckParticleList()</TT> has been added to
0133     <TT>G4VUserPhysicsList</TT> to check the consistency of the list of defined
0134     particles before instantiating the physics processes. For example,
0135     <TT>e+, e-</TT> and <TT>gamma</TT> should exist if any electromagnetic
0136     process is simulated... A fatal exception will be thrown if any particle
0137     type mandatory for the simulation is missing.<BR>
0138     It is possible to skip this check, by making use of the method
0139     <TT>DisableCheckParticleList()</TT> from <TT>G4VUserPhysicsList</TT>.</LI>

0146 <LI>All Low Energy Electromagnetic Physics process classes have been entirely
0147     redesigned (migrated) in the Geant4 toolkit in order to offer to users a
0148     coherent approach for the modeling of electromagnetic physical interactions.
0149     The software design is now common to both 'standard' and 'low energy'
0150     electromagnetic modules. These changes affect Livermore, Penelope,
0151     ICRU'73 ion and Geant4-DNA Physics. Users are invited to modify their own
0152     physics-list(s) in order to use these new processes and models.
0153     The web page indicated below describe how to use these new processes and
0154     models, with examples of physics list implementations and new features of
0155     the adopted common design:<BR>

0157     Please note that it is still possible to use previous implementation of the
0158     low energy processes for backward compatibility, however, these models are no
0159     longer maintained and will be removed in the near future. A warning message
0160     will also be displayed when running older low energy model versions.</LI>

0167 <LI>It is recommended to migrate user custom physics-lists by replacing
0168     the <TT>G4MultipleScattering</TT> physics process with the following:
0169     <UL>
0170     <LI><TT>G4eMultipleScattering</TT> for <TT>e+-</TT>;</LI>
0171     <LI><TT>G4MuMultipleScattering</TT> for muons;</LI>
0172     <LI><TT>G4hMultipleScattering</TT> for hadrons and ions.</LI>
0173     </UL>
0174     The former <TT>G4MultipleScattering</TT> still exists in the Geant4
0175     distribution but will be deleted in a future release.
0176     <P></P>
0177     Nuclear stopping power is no longer part of ionization processes, and is now
0178     responsible only for electronic stopping power; for simulation of nuclear
0179     stopping, a new process <TT>G4NuclearStopping</TT> should be added to
0180     custom physics-lists.</LI>

0198     whose system does not provide the library <TT>libz</TT>.
0199     To use this internal version, set the environment variable
0200     <TT>G4LIB_USE_ZLIB</TT>.
0201     Users who build with the standard Geant4 <TT>Configure</TT> script should

0226 <UL>
0227 <LI>A new stepper <TT>G4NystromRK4</TT> offers better computing performance in
0228     integrating the trajectories of charged particles in a magnetic field.
0229     It uses the standard Nystrom method and a novel analytical estimation of
0230     the integration error. This reduces greatly the number of field calls per
0231     integration step (from 10 to 3). It achieves comparable accuracy with
0232     <TT>G4ClassicalRK4</TT> in test cases. It can be used only for pure
0233     magnetic fields which are not time-dependent.</LI>
0234 <LI>A  new class <TT>G4CachedMagneticField</TT> caches the value of a magnetic
0235     field class, in order to reduce the number of calls to an expensive field
0236     calculation or interpolation method. For positions within the chosen radius
0237     of the previous position where it evaluated the field, it returns the last
0238     value of the field is automatically. It can be used only for pure magnetic
0239     fields which are not time-dependent.</LI>

0259 <LI>ICRU'73 ion model : the upper energy limit of ICRU'73 stopping power tables
0260     was extended to <TT>1 GeV/nucleon</TT> (compared to <TT>10 MeV/nucleon</TT>
0261     in the previous release). Revised tables were included for <TT>G4_WATER,

0269         up to <TT>1 MeV</TT>; proton excitation Born's model up to
0270         <TT>100 MeV</TT>; proton ionization Born's model up to <TT>100 MeV</TT>.</LI>
0271     <LI>Geant4-DNA models are valid for liquid water only and use now the
0272         <TT>G4_WATER</TT> NIST material as liquid water material definition.
0273         Users should define liquid water as <TT>G4_WATER</TT> in their

0288         for <TT>e+/e-</TT> in all other physics constructors of physics-lists
0289         (<TT>Option2, Option3, Livermore, Penelope</TT>).</LI>
0290     <LI><TT>G4GoudsmitSaundersonMscModel</TT> is a new model for <TT>e+/e-</TT>

0307     in <TT>G4NeutronInelasticCrossSections</TT> and
0308     <TT>G4ProtonInelasticCrossSections</TT> has been extended to <TT>100 TeV,</TT>
0309     by assuming a constant cross-section at very high energies.</LI>
0310 <LI>Glauber-Gribov cross-sections for ion-ion collisions are now available in
0311     the class <TT>G4GGNuclNuclCrossSection</TT>,
0312     spanning from <TT>0.1 MeV</TT> to <TT>100 TeV</TT>.</LI>
0313 <LI>The nucleon-nucleon and pion-nucleon partial cross-sections used in the
0314     Bertini cascade were reviewed and the incorrect cross-sections found below
0315     <TT>1 GeV</TT> were fixed. This results in slightly improved agreement
0316     with data below <TT>1 GeV</TT>.</LI>
0317 <LI>The CHIPS model has been extended with hadronic interactions covering all energies for all hadronic particles; in addition    hadron- and
0318     lepton-nuclear reactions  are extended to high energies (~TeV).
0319     It can be used by choosing the new <TT>CHIPS</TT> physics-list.
0320     CHIPS ion-ion elastic scattering model is also now available.</LI>
0321 <LI>An option was added to allow models for elastic scattering  to be treated in a similar way to inelastic models. Models can now be assigned to the

0376 <LI>Improved ability of visualization system to render Boolean solids.
0377     Certain cases involving very near co-planar faces used to result in
0378     incorrect visualization (though not incorrect tracking).
0379     An existing mechanism to deal with this has been improved; this mechanism
0380     used to shift slightly the position of one solid in a chosen direction.
0381     Now it attempts shifts in different directions by varying small amounts
0382     until one is found that does not give an error. The system still can not
0383     handle every situation. However it results in far fewer visualization
0384     inaccuracies than were seen previously in such difficult cases.</LI>
0385 <LI>Visualization attributes can now be individually set for each volume within
0386     a nested parameterization.</LI>
0387 <LI>Rich Trajectories and Rich Trajectory Points now include additional

0389     volume including all replica and copy numbers, etc.</LI>
0390 <LI>A new command, <TT>/vis/viewer/set/targetPoint</TT>, sets a specific point
0391     to be the center of the view. Helps with doing extreme zoom in to a

0394     output data in the <TT>gdd</TT> format used by the gMocren volume
0395     visualization tool. <TT>gMocrenFile</TT> can include volume data from
0396     sensitive detector volumes, or from command-based scoring meshes, in
0397     addition to detector geometry and trajectories. Use new command
0398     <TT>/vis/scene/add/psHits</TT> to add scorer hits to gMocren output.

0403     <TT>G4UI_USE_*</TT>.</LI>
0404 <LI><B>Qt</B>: Continued improvements to this new driver. The <TT>Qt</TT>
0405     visualization driver and the associated <TT>Qt</TT> User Interface now work
0406     well on almost all platforms and with both Qt3 and Qt4 (but still considered
0407     a Beta release due to a few rare combinations of commands on certain
0408     platforms that can cause crashes).</LI>
0409 <LI>PostScript printing: vector and bitmapped printing through the UI command
0410     <TT>/vis/ogl/printEPS</TT> is now fully functional for all OpenGL viewers
0411     (previously only for OGLIX and OGLSX). Related new commands are
0412     <TT>/vis/ogl/set/printSize</TT> and <TT>/vis/ogl/set/printFilename</TT>.</LI>
0413 <LI><B>HepRepFile</B>: new UI commands of the form <TT>/vis/heprep</TT> allow
0414     easy control of output file name and output directory, whether a file name
0415     should be reused (rather than having a sequential suffix appended at each
0416     new file) and whether culled geometry volumes should be included.
0417     Also fixed a bug in representation of <TT>G4Tubs</TT> which had caused
0418     wrong visualization for cases in which the tube was at an unusual angle.</LI>

0481 <H2>6. Known Run-Time Problems and Limitations</H2>
0482 <UL>
0483 <LI>Reports have been made of particle tracks stuck at a volume boundary or at
0484     an interface between volumes. This occurs infrequently, on the order of one
0485     step per 10^11, but can effect large productions. The behaviour involved
0486     particles which do not progress but move in very small steps, and as a
0487     result the simulation of this track never finishes.
0488     <UL>
0489     <LI>A partial solution is implemented in this release, which uses an
0490         existing mechanism to identify better these stuck tracks. It is able to
0491         find all such tracks in the setups reported, using a large multiple of
0492         the value of the geometrical tolerance for the setup. Users should pay
0493         attention that the value is chosen well for their setup in case they
0494         encounter a similar problem (using the existing functionality for
0495         setting this value).</LI>
0496     <LI>The treatment for these stuck tracks is to abandon the relevant track.
0497         This results in the track being killed by the <TT>G4Transportation</TT>
0498         process. A warning is issued (if compiled in verbose mode, the default)
0499         in the case that the energy of the track is above a threshold energy.
0500         Its default value is <TT>100 MeV</TT>. This value should be chosen by
0501         a user in order to get warning for all particles of energy important to
0502         your simulation. A new value can be assigned using the
0503         <TT>SetThresholdWarningEnergy</TT> method of
0504         <TT>G4Transportation</TT>.</LI>

0519 <H2>7. Compilation Warnings</H2>

0532 The following message may be written to standard output at the end of a program:

0534     G4Transportation: Statistics for looping particles
0535        Sum of energy of loopers killed:
0536        Max energy of loopers killed:
0537 </PRE>
0538 It provides the total energy (in <TT>MeV</TT>) of tracks  killed due to
0539 excessive number of steps ('looping') during the simulation, and the maximum
0540 energy of such a track. Such behaviour can be due to looping in magnetic fields
0541 or being abandoned due to being stuck at geometrical boundaries, as mentioned
0542 in <A href="#6.">Section 6</A>.
0543 <P></P>
0544 In case either of these reported energies is significant, we recommend
0545 increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
0546 each track killed. A user can change the threshold energy above which particles
0547 are killed more reluctantly (only after significant additional effort) using
0548 the method <TT>SetThresholdImportantEnergy</TT> of <TT>G4Transportation</TT>.
0549 The default value is <TT>250 MeV</TT>.

0946     <LI>Introducing <TT>G4SmartTrackStack</TT> class. By using this new stack
0947         as the urgent stack of <TT>G4StackManager</TT>, the next track popped
0948         up from the stack is not necessarily the last track stored in the

0950         long as such a track exists in the urgent stack. This mechanism is
0951         expected to improve the performance for ultra-large scale simulation
0952         such as LHC, by increasing the cache hit rate of the physics tables.<BR>
0953         The use of <TT>G4SmartTrackStack</TT> is temporarily optional. To use

0975         and set to 100 (200 for previous versions).
0976         Added <TT>MaxEnergyCut</TT> (<TT>10 GeV</TT> set in default).
0977         Added <TT>fRangeVectorStore</TT> to ensure that range-vector is

0980     <LI>A new method <TT>ResetConverters()</TT> has been added to

1514 <LI>ICRU'73 stopping power classes:
1515     <UL>
1516     <LI>Migrated to the <TT>G4VIonDEDXTable</TT> interface: access methods
1517         of physics vectors have changed (vectors can also be identified via
1518         atomic number of material if material is pure). Classes now deliver
1519         mass stopping powers instead of stopping powers per unit length.
1520         Any dependency on ICRU'73 material densities was removed (no densities
1521         are included in the classes any longer). Stopping power vectors are
1522         now only built on request and not anymore in the constructor.
1523         Affected classes: <TT>G4IronStoppingICRU73, G4MaterialStoppingICRU73</TT>
1524         and <TT>G4SimpleMaterialStoppingICRU73</TT>.</LI>

1529     <LI><TT>G4MaterialStoppingICRU73</TT>: extended energy range of revised
1530         ICRU'73 tables for water from <TT>0.025-10 MeV/u</TT> to

1532         Added new function <TT>AddPhysicsVectorFullRange()</TT> for creating
1533         corresponding physics vectors. Changed material name from

1547     and <TT>G4_NYLON-6/10</TT> to <TT>G4_NYLON-6-10</TT>, to allow matching
1548     with ion stopping power data files. Old names can still be used for
1549     backward compatibility. Changed density of <TT>G4_GRAPHITE</TT> according
1550     to PDG-2008, added new material <TT>G4_GRAPHITE_POROUS</TT>.</LI>

1556     power tables for ions. Added new method <TT>BuildPhysicsVector()</TT>
1557     which invokes the build of physics vectors on demand in the initialisation
1558     phase. Added method <TT>BuildPhysicsVector()</TT> according to base class
