Geant4 11.2 - patch-01 Release Notes
|
|
------------------------------------
|
|
|
|
16 February 2024
|
|
|
|
List of fixes included in this public patch since the public release 11.2.0:
|
|
|
|
o Configuration
|
|
-------------
|
|
+ CMake:
|
|
o Added -F flag on macOS with a framework build of Qt.
|
|
Addressing problem report #2589.
|
|
o Fixed detection of SoQt/Xt packages, by manually checking versions of
|
|
found packages. Geant4 only requires a minimum version.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ solids/CSG:
|
|
o In wrapper G4UTrap, use GetThetaCosPhi() and GetThetaSinPhi() in
|
|
method GetVertices(); this overcomes a problem with trapezoid reported
|
|
in CMSSW after migration to VecGeom 1.2.6.
|
|
Also fixed typo in method SetAllParameters(), setter used in
|
|
parameterisation of shape dimensions.
|
|
|
|
o Global:
|
|
------
|
|
+ G4PhysicsModelCatalog: added ID for the Light-Ion QMD model.
|
|
+ Updated date and version for 11.2.1.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ constructors/electromagnetic
|
|
o G4GammaGeneralProcess: fixed sampling of muon pair production.
|
|
Addressing problem report #2543.
|
|
o G4EmStandardPhysics_option3: restore step limit type to use
|
|
'fUseDistanceToBoundary' and set default RangeFactor from 0.03 to 0.04,
|
|
fixing inaccuracy in medical benchmarks.
|
|
+ constructors/gamma_lepto_nuclear
|
|
o G4NeutrinoPhysics: fixed neutrino physics instantiation.
|
|
Addressing problem report #2594.
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ dna
|
|
o G4DNABornAngle: fixed numerical problem; added protection for cosTheta;
|
|
use relativistic formula for maximum energy transfer to delta-electrons.
|
|
+ lowenergy
|
|
o G4MicroElecInelasticModel_new: fixed Coverity report for memory leak at
|
|
exit. Minor code cleanup.
|
|
o G4MicroElecLOPhononModel: minor code cleanup.
|
|
+ standard
|
|
o G4IonICRU73Data: fix for the case when target material has an element
|
|
with Z>92; improved debug printouts. In the Lindhard-Sorensen model to
|
|
compute dEdx the first try is to take it from ICRU73 or ICRU90 data,
|
|
if this class returns zero, then dEdx is computed from G4GenericIon
|
|
and effective charge. Addressing problem report #2586.
|
|
+ utils
|
|
o G4VEmProcess, G4VEnergyLossProcess: minor CPU optimisation with
|
|
reduction of number of calls for log() of kinetic energy.
|
|
+ xrays
|
|
o G4GaussXTRadiator, G4VXTRenergyLoss: flexible summation in SpectralXTRdEdx;
|
|
clean-up in GetStackFactor() based on std::complex methods.
|
|
o In G4Scintillation::sample_time(), refactored the scintillation time
|
|
sampling.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ cross_sections
|
|
o G4KokoulinMuonNuclearXS: use faster interface to G4PhysicsVector.
|
|
o G4ElectroNuclearCrossSection: added low-energy limit of 100 MeV for
|
|
cross-section.
|
|
+ management
|
|
o G4HadronicProcess: explicitly define cross-section type per particle
|
|
type, this might provide some CPU speedup.
|
|
+ models/de_excitation
|
|
o G4FermiBreakUpVI, G4FermiFragmentsPoolVI: fix in production of fake
|
|
excited isomeres, by moving the check on lifetime limit to the Initialise()
|
|
method of the model, allowing to change this limit in an application;
|
|
do not consider decay chains with no final state.
|
|
Addressing problem report #2584.
|
|
o G4StatMFChannel: replaced use of C-arrays with std::vector, clearing
|
|
compilation warnings on gcc compiler when LTO settings are enabled.
|
|
+ models/lend
|
|
o Fixed compilation error on recent Windows VC++ compiler 17.8.3 for use
|
|
of std::isfinite(). Addressing problem report #2582.
|
|
o Fixed compilation warnings on gcc compiler when LTO settings are
|
|
enabled.
|
|
+ models/particle_hp
|
|
o G4ParticleHPFissionFS, G4ParticleHPFFFissionFS: added extra protections
|
|
against cases when fission data are not available for some isotopes.
|
|
Addressing problem #2590.
|
|
o G4ParticleHPFSFissionFS, G4ParticleHPFissionBaseFS: replaced use of
|
|
C-arrays with std::vector, clearing compilation warnings on gcc
|
|
compiler when LTO settings are enabled.
|
|
+ qmd
|
|
o Fixed model ID (model_LightIonQMDModel) in G4LightIonQMDReaction.
|
|
+ radioactive_decay
|
|
o G4Radioactivation: added DBL_EPSILON check on transition energy for
|
|
metastables to prevent creation of zero energy levels which have no
|
|
decay products.
|
|
o G4BetaPlusDecay, G4BetaMinusDecay: fixed sampling algorithm.
|
|
Addressing problem report #2588.
|
|
|
|
o Run:
|
|
---
|
|
+ Correctly report number of threads from G4TaskRunManager.
|
|
|
|
o Tracking:
|
|
--------
|
|
+ G4TrackingMessenger: fixed Coverity report for memory leak at exit,
|
|
by moving static thread-local variable to become class member, as
|
|
G4TrackingManager and its messenger are thread-local by nature.
|
|
|
|
o Examples:
|
|
--------
|
|
+ basic/B2
|
|
o Updated PrimaryGeneratorAction::GeneratePrimaries() in B2a and B2b
|
|
examples to avoid placing of the initial position on the world
|
|
boundary. Updated READMEs.
|
|
+ extended/electromagnetic/TestEm1
|
|
o Updated initial gun position in PrimaryGeneratorAction to not lay on
|
|
the world volume surface.
|
|
+ extended/electromagnetic/TestEm5
|
|
o Updated initial gun position in PrimaryGeneratorAction to not lay on
|
|
the world volume surface.
|
|
o In TrackingAction, added a protection against potential wrong argument
|
|
to std::acos(), rarely happening for very high energy projectile
|
|
particles.
|
|
+ extended/electromagnetic/TestEm11
|
|
o Updated initial gun position in PrimaryGeneratorAction to not lay on
|
|
the world volume surface.
|
|
+ extended/electromagnetic/TestEm16
|
|
o Updated READMEs to document all macros.
|
|
+ extended/medical/dna/neuron
|
|
o Cleanup to reduce number of Valgrind warnings; applied coding style
|
|
recommendations; removed commented lines, removed unused methods;
|
|
substituted C-arrays with vectors; improved algorithm of reading of
|
|
data file.
