0002 Geant4 11.2 - patch-02 Release Notes
0003 ------------------------------------
0004
0005 21 June 2024
0006
0007 List of fixes included in this public patch since the public release 11.2.1:
0008
0009 o Configuration
0010 -------------
0011 + CMake:
0012 o Fix to do not export HDF5 version to Geant4Config.
0013 o Fixed find_package(SoXt) and find_package(SoWin).
0014 o In main CMake source script, VTK driver library requires the application
0015 of VTK's vtk_module_autoinit cmake function, but the existence of the
0016 target was not checked, leading to configure time errors. Check for the
0017 existence of both G4visVTK and G4visVTK-static targets before applying
0018 vtk_module_autoinit. Addressing problem report #2600.
0019 o Mention the possibility of using cvmfs datasets in the cmake configuration.
0020 o Updated FindPythia6 module to account for lib64.
0021 Applies GitHub PR#63 (https://github.com/Geant4/geant4/pull/63).
0022 o Disabled use of FindPythia6 outside of internal Geant4 examples.
0023 o Updated FindPythia8 module to reduce capability to only that required by
0024 py8decayer example and emit error if used in project outside Geant4 or
0025 py8decayer. Applies GitHub PR#68 (https://github.com/Geant4/geant4/pull/68).
0026 o Fixed escaping of regex in geant4_module_check to satisfy latest Python3.
0027 o Updated dataset: G4NDL-4.7.1.
0028
0029 o Analysis
0030 --------
0031 + Do not delete G4Accumulable<T> default constructor, as it prevents from
0032 using it in an array without an explicit initialization in the header.
0033 + Fixed wrong conversion to G4String in G4THnToolsManager, leading to
0034 compilation error on gcc compiler with C++23 Standard enabled.
0035
0036 o Digits_Hits
0037 -----------
0038 + Fixed compilation error in G4THitsMap on macOS/clang with C++23 Standard
0039 enabled.
0040
0041 o Externals
0042 ---------
0043 + g4tools:
0044 o Fixed compilation warnings on gcc when LTO settings are enabled.
0045 o Fixed string assignments in 'window' and 'pixwin', to support either
0046 UNICODE or UTF-16 encoding on Windows. Addressing problem report #2599.
0047 + ptl:
0048 o Changed Windows.h to windows.h, to allow build Windows/MinGW.
0049 Not relevant for native VC++ builds.
0050
0051 o Geometry
0052 --------
0053 + magnetic_field:
0054 o Fixed potential uninitialised data, detected in ATLAS LTO builds.
0055 + navigation:
0056 o Fixed compilation error in G4Navigator on Windows VC++ with C++20 Standard
0057 enabled. Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0058 + solids/specific:
0059 o Use std::size_t for array sizes in G4PolyhedraSide and G4PolyPhiFace,
0060 fixing compilation warnings on gcc when LTO settings are enabled.
0061 + volumes:
0062 o Use std::map instead of std::vector to define G4LogicalSkinSurfaceTable,
0063 to speedup search of skin surfaces in large tables, as already done
0064 previously for G4LogicalBorderSurface. Addressing problem report #2598.
0065
0066 o Global
0067 ------
0068 + Changed Windows.h to windows.h, to allow build Windows/MinGW.
0069 Not relevant for native VC++ builds. Use _WIN32 to detect Windows system.
0070 + Fixed compilation error in G4PhysicsModelCatalog on Windows VC++ with
0071 C++20 Standard enabled.
0072 Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0073 + Provide helpful error message when GEANT4_DATA_DIR is set to an invalid
0074 location.
0075 + Updated date and version for 11.2.2.
0076
0077 o Intercoms
0078 ---------
0079 + G4UIparsing: checking either 'int' or 'long int' parameter value are
0080 within range of G4int or G4long.
0081 + Fix in G4GenericMessenger::DeclareMethod() which was wrongly converting
0082 valid Boolean parameters. Improved SetNewValue() function.
0083 Addressing problem report #2606.
0084
0085 o Interfaces
0086 ----------
0087 + Use std::size_t as arrays size in G4InteractorMessenger and G4UIArrayString,
0088 fixing compilation warnings on gcc when LTO settings are enabled
0089 + Fixed string assignments in G4Win32 and G4UIWin32, to support either
0090 UNICODE or UTF-16 encoding on Windows. Addressing problem report #2599.
0091
0092 o Materials
0093 ---------
0094 + Fix in G4NistMaterialBuilder::HepAndNuclearMaterials(): G4_BRASS,
0095 G4_BRONZE and G4_STAILESS_STEEL are now defined using mass fractions
0096 of components instead of number of atoms, in order to have more natural
0097 description. Addressing problem report #2601.
0098 Results may be changed on level of 10^-5 due to numerical differences.
0099
0100 o Persistency
0101 -----------
0102 + GDML:
0103 o Disabled schema validation on Windows platforms, as XercesC currently does
0104 support only 'http'.
0105 o Fix in schema module gdml_solids.xsd for tessellated solid semantics, to
0106 correctly reference facet types. Fixes schema validation errors which may
0107 occur on some custom XSD validation tools (fix included in GDML-3.1.7).
0108 o Use std::map instead of std::vector to iterate on logical-skin surfaces
0109 in G4GDMLWriteStructure::GetSkinSurface().
0110 Part of fix addressing problem report #2598.
0111
0112 o Physics Lists
0113 -------------
0114 + lists:
0115 o G4PhysListFactory: added three new variants of 'Shielding' physics list,
0116 using the model G4LightIonQMDReaction: 'ShieldingLIQMD', 'ShieldingLIQMD_HP'
0117 and 'ShieldingLIQMD_HPT'. Addressing problem report #2615.
0118 Note that 'ShieldingLIQMD' and 'ShieldingLIQMD_HP' refer to the same
0119 configuration, the latter is introduced only for consistency.
0120
0121 o Processes - Electromagnetic
0122 ---------------------------
0123 + dna:
0124 o Fixed compilation error on Windows VC++ with C++20 Standard enabled.
0125 Added missing declarations for TG4MoleculeShoot specialisations on G4Track.
0126 Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0127 o Fixed compilation error on macOS/clang with C++23 enabled, for the use
0128 of std::function in G4OctreeFinder.
0129 + standard:
0130 o G4BetheHeitler5DModel: fixed computation of sinTheta sampling and added
0131 checks on arguments of G4Exp in SampleSecondaries() method, to avoid FPE
0132 problems in the case of -O3 optimisation on alma9.
0133 + utils:
0134 o G4EmUtility: simplified computation of cross-section maximum for
0135 discrete processes to fix FPE issues on alma9 when -O3 compiler
0136 option is used.
0137 o Fixed compilation error in G4EmConfigurator on Windows VC++ with
0138 C++20 Standard enabled.
0139 Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0140
0141 o Processes - Hadronic
0142 --------------------
0143 + models/binary_cascade:
0144 o Removed throwing of exception if momentum cannot be corrected in rare
0145 cases for D + H around 1600 MeV; the initial state is now kept unchanged
0146 instead.
0147 + models/coherent_elastic:
0148 o Fixed compilation warnings for potentially initialised local variables
0149 in SampleThetaCMS() for G4DiffuseElastic and G4NuclNuclDiffuseElastic.
0150 + models/lend:
0151 o Fixed compilation warnings for potentially initialised local variables
0152 in ptwXY_createFromFunctionZeroCrossing().
0153 o Define _USE_MATH_DEFINES before inclusion of <cmath> to define
0154 non-standard math macros such as M_PI on Windows. Use _WIN32 instead of
0155 WIN32 to detect Windows system. Use basetsd.h instead of BaseTsd.h to
0156 allow for compilation on Windows/MinGW.
0157 + models/inclxx:
0158 o Fix in G4INCLInteractionAvatar to not use local energy for all antibaryons.
0159 + models/particle_hp:
0160 o G4CrossSectionHP: fixed method taking into account temperature effect
0161 (the difference due to this fix is small).
0162 Fixed elastic and capture cross-sections in Argon, by using only the main
0163 isotope Z=18, A=40 (there was up to 50% overestimation of cross-sections
0164 due to wrong data for rare isotopes of argon).
0165 Fixed cross-sections for rare target atoms Promethium, Astatine, Radon
0166 and Francium.
0167 o Fixed compilation error in G4ParticleHPManager and G4ParticleHPNames on
0168 Windows VC++ with C++20 Standard enabled.
0169 Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0170 o Fixed remaining compilation warnings on gcc compiler when LTO settings
0171 are enabled.
0172 + radioactive_decay:
0173 o G4BetaPlusDecay, G4BetaMinusDecay: added extra numerical protection on
0174 level of 1 eV to avoid precision lost and production of neutrino with
0175 negative kinetic energy. In case Q-value is bigger than mass difference,
0176 betas in the tail of the spectrum may have more energy than residual free
0177 energy. To minimize the non-conservation of 4-momentum, in such cases,
0178 neutrino and daughter nucleus are given 1 eV, leading to non conservation
0179 of linear momentum because momentum of beta is not counterbalanced.
0180
0181 o processes - solidstate/phonon
0182 -----------------------------
0183 + Fixed compilation error in G4LatticeManager on Windows VC++ with
0184 C++20 Standard enabled.
0185 Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0186
0187 o processes/optical
0188 -----------------
0189 + G4OpBoundaryProcess: correctly calculate Fresnel reflection/refraction,
0190 when material property TRANSMITTANCE is specified. The ratio of Fresnel
0191 reflection/refraction now does not change when a non-zero transmission is
0192 specified. Previously, if transmission of X% was specified, there would be
0193 transmission of X% as expected, but the ratio of Fresnel refraction to
0194 Fresnel reflection would be set to X%. Addressing problem report #2578.
0195
0196 o Track
0197 -----
0198 + Fixed compilation error in G4VParticleChange on Windows VC++ with
0199 C++20 Standard enabled.
0200 Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
0201
0202 o Visualization
0203 -------------
0204 + management:
0205 o G4VisExecutive: fixed use of static symbol 'fVerbosity' and replaced
0206 with call to dedicated static method, to avoid linkage problems on Windows.
0207 + Qt3D:
0208 o Fixed compilation error on Windows for ambiguous string assignment in
0209 G4Qt3DSceneHandler::CreateNewNode().
0210 + Vtk:
0211 o Porting code to compile on Windows Visual-Studio.
0212 o Fixed Ubuntu 22 & VTK 9.1 compilation error.
0213
0214 o Data
0215 ----
0216 + G4NDL-4.7.1:
0217 o Removed all files for Argon-36 and Argon-38 as significantly different
0218 from those of ENDF/B-VIII.0.
0219 o Reprocessed thermal scattering files after fixing a problem in NJOY.
0220 Addressing problem report #2552.
