Geant4 11.2 - patch-02 Release Notes
------------------------------------
21 June 2024
List of fixes included in this public patch since the public release 11.2.1:
o Configuration
-------------
+ CMake:
o Fix to do not export HDF5 version to Geant4Config.
o Fixed find_package(SoXt) and find_package(SoWin).
o In main CMake source script, VTK driver library requires the application
of VTK's vtk_module_autoinit cmake function, but the existence of the
target was not checked, leading to configure time errors. Check for the
existence of both G4visVTK and G4visVTK-static targets before applying
vtk_module_autoinit. Addressing problem report #2600.
o Mention the possibility of using cvmfs datasets in the cmake configuration.
o Updated FindPythia6 module to account for lib64.
Applies GitHub PR#63 (https://github.com/Geant4/geant4/pull/63).
o Disabled use of FindPythia6 outside of internal Geant4 examples.
o Updated FindPythia8 module to reduce capability to only that required by
py8decayer example and emit error if used in project outside Geant4 or
py8decayer. Applies GitHub PR#68 (https://github.com/Geant4/geant4/pull/68).
o Fixed escaping of regex in geant4_module_check to satisfy latest Python3.
o Updated dataset: G4NDL-4.7.1.
o Analysis
--------
+ Do not delete G4Accumulable<T> default constructor, as it prevents from
using it in an array without an explicit initialization in the header.
+ Fixed wrong conversion to G4String in G4THnToolsManager, leading to
compilation error on gcc compiler with C++23 Standard enabled.
o Digits_Hits
-----------
+ Fixed compilation error in G4THitsMap on macOS/clang with C++23 Standard
enabled.
o Externals
---------
+ g4tools:
o Fixed compilation warnings on gcc when LTO settings are enabled.
o Fixed string assignments in 'window' and 'pixwin', to support either
UNICODE or UTF-16 encoding on Windows. Addressing problem report #2599.
+ ptl:
o Changed Windows.h to windows.h, to allow build Windows/MinGW.
Not relevant for native VC++ builds.
o Geometry
--------
+ magnetic_field:
o Fixed potential uninitialised data, detected in ATLAS LTO builds.
+ navigation:
o Fixed compilation error in G4Navigator on Windows VC++ with C++20 Standard
enabled. Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
+ solids/specific:
o Use std::size_t for array sizes in G4PolyhedraSide and G4PolyPhiFace,
fixing compilation warnings on gcc when LTO settings are enabled.
+ volumes:
o Use std::map instead of std::vector to define G4LogicalSkinSurfaceTable,
to speedup search of skin surfaces in large tables, as already done
previously for G4LogicalBorderSurface. Addressing problem report #2598.
o Global
------
+ Changed Windows.h to windows.h, to allow build Windows/MinGW.
Not relevant for native VC++ builds. Use _WIN32 to detect Windows system.
+ Fixed compilation error in G4PhysicsModelCatalog on Windows VC++ with
C++20 Standard enabled.
Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
+ Provide helpful error message when GEANT4_DATA_DIR is set to an invalid
location.
+ Updated date and version for 11.2.2.
o Intercoms
---------
+ G4UIparsing: checking either 'int' or 'long int' parameter value are
within range of G4int or G4long.
+ Fix in G4GenericMessenger::DeclareMethod() which was wrongly converting
valid Boolean parameters. Improved SetNewValue() function.
Addressing problem report #2606.
o Interfaces
----------
+ Use std::size_t as arrays size in G4InteractorMessenger and G4UIArrayString,
fixing compilation warnings on gcc when LTO settings are enabled
+ Fixed string assignments in G4Win32 and G4UIWin32, to support either
UNICODE or UTF-16 encoding on Windows. Addressing problem report #2599.
o Materials
---------
+ Fix in G4NistMaterialBuilder::HepAndNuclearMaterials(): G4_BRASS,
G4_BRONZE and G4_STAILESS_STEEL are now defined using mass fractions
of components instead of number of atoms, in order to have more natural
description. Addressing problem report #2601.
Results may be changed on level of 10^-5 due to numerical differences.
o Persistency
-----------
+ GDML:
o Disabled schema validation on Windows platforms, as XercesC currently does
support only 'http'.
o Fix in schema module gdml_solids.xsd for tessellated solid semantics, to
correctly reference facet types. Fixes schema validation errors which may
occur on some custom XSD validation tools (fix included in GDML-3.1.7).
o Use std::map instead of std::vector to iterate on logical-skin surfaces
in G4GDMLWriteStructure::GetSkinSurface().
Part of fix addressing problem report #2598.
o Physics Lists
-------------
+ lists:
o G4PhysListFactory: added three new variants of 'Shielding' physics list,
using the model G4LightIonQMDReaction: 'ShieldingLIQMD', 'ShieldingLIQMD_HP'
and 'ShieldingLIQMD_HPT'. Addressing problem report #2615.
Note that 'ShieldingLIQMD' and 'ShieldingLIQMD_HP' refer to the same
configuration, the latter is introduced only for consistency.
o Processes - Electromagnetic
---------------------------
+ dna:
o Fixed compilation error on Windows VC++ with C++20 Standard enabled.
Added missing declarations for TG4MoleculeShoot specialisations on G4Track.
Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
o Fixed compilation error on macOS/clang with C++23 enabled, for the use
of std::function in G4OctreeFinder.
+ standard:
o G4BetheHeitler5DModel: fixed computation of sinTheta sampling and added
checks on arguments of G4Exp in SampleSecondaries() method, to avoid FPE
problems in the case of -O3 optimisation on alma9.
+ utils:
o G4EmUtility: simplified computation of cross-section maximum for
discrete processes to fix FPE issues on alma9 when -O3 compiler
option is used.
o Fixed compilation error in G4EmConfigurator on Windows VC++ with
C++20 Standard enabled.
Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
o Processes - Hadronic
--------------------
+ models/binary_cascade:
o Removed throwing of exception if momentum cannot be corrected in rare
cases for D + H around 1600 MeV; the initial state is now kept unchanged
instead.
+ models/coherent_elastic:
o Fixed compilation warnings for potentially initialised local variables
in SampleThetaCMS() for G4DiffuseElastic and G4NuclNuclDiffuseElastic.
+ models/lend:
o Fixed compilation warnings for potentially initialised local variables
in ptwXY_createFromFunctionZeroCrossing().
o Define _USE_MATH_DEFINES before inclusion of <cmath> to define
non-standard math macros such as M_PI on Windows. Use _WIN32 instead of
WIN32 to detect Windows system. Use basetsd.h instead of BaseTsd.h to
allow for compilation on Windows/MinGW.
+ models/inclxx:
o Fix in G4INCLInteractionAvatar to not use local energy for all antibaryons.
+ models/particle_hp:
o G4CrossSectionHP: fixed method taking into account temperature effect
(the difference due to this fix is small).
Fixed elastic and capture cross-sections in Argon, by using only the main
isotope Z=18, A=40 (there was up to 50% overestimation of cross-sections
due to wrong data for rare isotopes of argon).
Fixed cross-sections for rare target atoms Promethium, Astatine, Radon
and Francium.
o Fixed compilation error in G4ParticleHPManager and G4ParticleHPNames on
Windows VC++ with C++20 Standard enabled.
Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
o Fixed remaining compilation warnings on gcc compiler when LTO settings
are enabled.
+ radioactive_decay:
o G4BetaPlusDecay, G4BetaMinusDecay: added extra numerical protection on
level of 1 eV to avoid precision lost and production of neutrino with
negative kinetic energy. In case Q-value is bigger than mass difference,
betas in the tail of the spectrum may have more energy than residual free
energy. To minimize the non-conservation of 4-momentum, in such cases,
neutrino and daughter nucleus are given 1 eV, leading to non conservation
of linear momentum because momentum of beta is not counterbalanced.
o processes - solidstate/phonon
-----------------------------
+ Fixed compilation error in G4LatticeManager on Windows VC++ with
C++20 Standard enabled.
Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
o processes/optical
-----------------
+ G4OpBoundaryProcess: correctly calculate Fresnel reflection/refraction,
when material property TRANSMITTANCE is specified. The ratio of Fresnel
reflection/refraction now does not change when a non-zero transmission is
specified. Previously, if transmission of X% was specified, there would be
transmission of X% as expected, but the ratio of Fresnel refraction to
Fresnel reflection would be set to X%. Addressing problem report #2578.
o Track
-----
+ Fixed compilation error in G4VParticleChange on Windows VC++ with
C++20 Standard enabled.
Based on [GitHub PR#69](https://github.com/Geant4/geant4/pull/69).
o Visualization
-------------
+ management:
o G4VisExecutive: fixed use of static symbol 'fVerbosity' and replaced
with call to dedicated static method, to avoid linkage problems on Windows.
+ Qt3D:
o Fixed compilation error on Windows for ambiguous string assignment in
G4Qt3DSceneHandler::CreateNewNode().
+ Vtk:
o Porting code to compile on Windows Visual-Studio.
o Fixed Ubuntu 22 & VTK 9.1 compilation error.
o Data
----
+ G4NDL-4.7.1:
o Removed all files for Argon-36 and Argon-38 as significantly different
from those of ENDF/B-VIII.0.
o Reprocessed thermal scattering files after fixing a problem in NJOY.
Addressing problem report #2552.
o Examples
--------
+ advanced/ChargeExchangeMC
o Disabled GDML schema validation.
+ advanced/hadrontherapy:
o Fixed compilation error on Windows VC++ with C++20 Standard enabled.
+ medical_linac:
o Fixed geometry of medical linear accelerator's collimator.
+ extended/biasing:
o Fixed URls in documentation.
+ extended/eventgenerator:
o Updated CMake scripts to use new Pythia8 setup/build variables.
+ extended/hadronic/FlukaCern/ProcessLevel/FinalState:
+ extended/hadronic/Hadr09:
o Fixed compilation error on Windows VC++ with C++20 Standard enabled.
+ extended/medical/DICOM:
o Corrected symbols for Chlorine and Potassium elements in function
InitialisationOfMaterials().
+ extended/parameterisations/Par04
o Bump scipy version according to
GitHub Dependabot PR#66(https://github.com/Geant4/geant4/pull/66).
