Geant4 10.7 - patch-03 Release Notes
|
|
------------------------------------
|
|
|
|
19 November 2021
|
|
|
|
List of fixes included in this public patch since the public release 10.7.p02:
|
|
|
|
o Configuration
|
|
-------------
|
|
+ CMake:
|
|
o Renamed Geant4::HDF5 to hdf5::hdf5 to be compatible with imported
|
|
targets provided since CMake 3.20. Addressing problem report #2426.
|
|
|
|
o Environments:
|
|
------------
|
|
+ G4py
|
|
o Removed binding to obsolete member functions of G4Sphere and G4Tubs.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ divisions:
|
|
o Make G4PVDivision and G4ReplicatedSlice inherit from G4PVReplica
|
|
rather than G4VPhysicalVolume, in order to have instances properly
|
|
cloned in MT mode.
|
|
o Fixed bug in G4ParameterisationTrd for positioning calculation.
|
|
Debug messages cleanup.
|
|
+ management:
|
|
o Provide operator<<() as a free function for G4UAdapter to support
|
|
Geant4Py.
|
|
+ navigation:
|
|
o G4PhantomParameterisation: reduced warning messages in GetReplicaNo()
|
|
function; issue warning only when difference is bigger than
|
|
'kCarTolerance'. Addressing problem report #2314.
|
|
+ solids/Boolean:
|
|
o In G4BooleanSolid, use G4RecursiveMutex in place of G4Mutex in
|
|
GetPolyhedron() to avoid potential deadlocks in visualisation
|
|
in recursive Boolean operations.
|
|
+ solids/specific:
|
|
o More accurate calculation of distance from point to triangle
|
|
in G4TriangularFacet. Addressing problem report #2401.
|
|
o Added missing accessor in G4UTet.
|
|
+ volumes:
|
|
o Use same strategy for cloning solids for replicated volumes types in
|
|
G4GeometryWorkspace (required for having proper treatment of divided
|
|
volumes). Cleanup of unused verbose printouts.
|
|
o G4PVReplica: moved internal defines for MT split data to source.
|
|
Avoid deletion of rotation matrix for replication in Phi in destructor
|
|
as not necessary. Some code cleanup.
|
|
|
|
o Global:
|
|
------
|
|
+ Updated date and version for 10.7.p03.
|
|
|
|
o Materials:
|
|
---------
|
|
+ Corrected calculations in G4DensityEffectCalculator.
|
|
Addressing problem report #2330.
|
|
+ G4IonisParamMat: return exact computations according to the original
|
|
publication. Addressing problem report #2334.
|
|
|
|
o Parameterisations/gflash
|
|
------------------------
|
|
+ Fixes in GFlashSamplingShowerParameterisation in the parameters
|
|
definition.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ ASCII:
|
|
o Change prefix to free math functions in G4tgrEvaluator source, to avoid
|
|
potential clashes with system functions carrying same name/signature.
|
|
Addressing problem report #2444.
|
|
+ GDML
|
|
o G4GDMLWriteStructure: added fatal exception in AssemblyWrite() for the
|
|
case of nested assemblies, not yet supported for exporting.
|
|
o G4GDMLParser: added utility method to retrieve a generic physical
|
|
volume by its name.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ constructors/gamma_lepto_nuclear
|
|
o G4EmExtraPhysics: enable synchrotron radiation only for really stable
|
|
particles. Fixed typo in registering positron-nuclear process; register
|
|
model for e-/e+-nuclear in case of general processes, avoid registering
|
|
synchroton radiation twice for e-/e+.
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ standard
|
|
o G4BetheBlochModel: fixed computation of dedx for alpha if ICRU90 data
|
|
are used. Addressing problem report #2414.
|
|
+ utils
|
|
o Fix in G4OpticalParametersMessenger for UI command changing incorrect
|
|
parameter. Addressing problem report #2392.
|
|
+ xrays
|
|
o G4Cerenkov: added protection against too small steps (still addressing
|
|
problem report #1992).
|
|
o G4GaussXTRadiator, G4VXTRenergyLoss: added Gauss-distributed regular
|
|
radiator and accessors for angle distribution range.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ cross_sections
|
|
o G4NeutronCaptureXS: fixed bug in isotope data access.
|
|
+ models/de_excitation
|
|
o In G4PhotonEvaporation, changed de-excitation logic from levels, which
|
|
has no data on transitions: instead of transition to closest level
|
|
continue transition is performed.
|
|
Attempting fix for problem report #2434, by reducing production of
|
|
fragments with high excitation and high angular momentum.
|
|
+ models/particle_hp
|
|
o Bug fix in G4ParticleHPLabAngularEnergy.
|
|
+ models/util
|
|
o G4SampleResonance: bug-fix in the method GetMinimumMass() in the use
|
|
case rare and light decay channels (e.g. e+ e-) are included for
|
|
hadronic resonances. Addressing problem report #2299.
|
|
|
|
o Run
|
|
---
|
|
+ G4VModularPhysicsList: fixed destruction of the vector of
|
|
G4VPhysicsConstructor for the case when physics list is created
|
|
but physics is not built.
|
|
|
|
o Tracking
|
|
--------
|
|
+ G4SteppingManager: Making sure Transportation limits the step if a volume
|
|
boundary in a parallel world is co-limiting the step.
|
|
Addressing problem report #2240.
|
|
|
|
o Examples:
|
|
--------
|
|
+ advanced/ICRP110_HumanPhantoms:
|
|
o Updated URL for data download.
|
|
+ advanced/STCyclotron:
|
|
o Added protection against potential division by zero in function
|
|
STCyclotronRun::EndOfRun().
|
|
+ extended/hadronic:
|
|
o Hadr01: in HistoManager, DetectorConstruction and DetectorMessenger
|
|
corrected counting of leaking neutrons.
|
|
Addressing problem report #2441.
|
|
+ extended/persistency:
|
|
o G01: Fixed minor overlaps in assembly.gdml and axes.gdml samples.
|
|
o G02, G03: Fixed visualisation settings in input macros.
