|
|
------------------------------------
|
|
|
|
8 March 2022
|
|
|
|
List of fixes included in this public patch since the public release 11.0:
|
|
|
|
o Configuration
|
|
-------------
|
|
+ CMake:
|
|
o Adding missing G4ptl and G4tasking libraries to link list in
|
|
geant4-config script. Addressing GitHub PR#37.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ Fix in notifying about closing file in G4GenericAnalysisManager.
|
|
|
|
o Externals:
|
|
---------
|
|
+ Fix in CMAke script to export built-in PTL include directory to include
|
|
path list for use of geant4-config.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ solids/Boolean:
|
|
o In G4MultiUnion, added alternative signature for AddNode() taking a
|
|
pointer to solid. Added 'const' qualification to transformation passed
|
|
as argument. Addressing problem report #2457.
|
|
|
|
o Global:
|
|
------
|
|
+ G4String: provide overload G4String::operator[](int) to workaround MSVC
|
|
compiler error C2666. Addressing problem report #2463.
|
|
+ Updated date and version for 11.0.1.
|
|
|
|
o Intercoms:
|
|
---------
|
|
+ Check and set proper argument types for each individual argument when
|
|
G4GenericMessenger::DeclareMethod() is used.
|
|
Addressing problem report #2420.
|
|
|
|
o Materials:
|
|
---------
|
|
+ G4MaterialPropertiesTable: set G4MaterialPropertyVector verbosity to 1.
|
|
+ G4DensityEffectData: fixed typos in the density effect data table for 8
|
|
materials; the most significant fix is for G4_Tm; of minor entity for
|
|
G4_Be, G4_Mg, G4_Fe, and G4_Y. Addressing problem report #2423.
|
|
+ G4SandiaTable: fixed compilation warning on unused variable.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ ASCII:
|
|
o Corrected wrong automatic conversion degree-radian for G4Polycone phi
|
|
angle parameter. Based on GitHub PR#36.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ constructors/electromagnetic
|
|
o G4EmStandardPhysics_option3: use options providing more accurate
|
|
simulation without loss of CPU performance: set RangeFactor to 0.03;
|
|
use 'SafetyPlus' step limitation instead of 'DistanceToBoundary'.
|
|
Significantly improving fanoCavity results.
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ low-energy
|
|
o G4MicroElecInelasticModel_new: changed interpolate() method; making a
|
|
choice between log-log, lin-log, and lin-lin interpolations and added a
|
|
protection for zero input energy. When sampling transition, the choice
|
|
is implemented for transition from atomic level and Fermi level.
|
|
Should fix rare crash observed in this model.
|
|
o Prefer pointer to 'const G4Material' where possible.
|
|
o G4hIonEffChargeSquare, G4PenelopeRayleighModel,
|
|
G4PenelopeRayleighModelMI: fixed compilation warning on unused variable.
|
|
+ standard
|
|
o G4UniversalFluctuation: introduced new protected method SampleGlandz(),
|
|
which provides sampling of non-Gauss fluctuations; improved arithmetics;
|
|
same results as in release 11.0.0.
|
|
o G4UrbanFluctuation: reorganized version of fluctuation model from
|
|
release 10.7 in SampleGlandz() method.
|
|
o G4UniversalFluctuation, G4UrbanFluctuation: use the same fw=4 and a0=42
|
|
parameters of the model providing similar fluctuation results for small
|
|
steps in thin layers as in version 10.7.
|
|
Addressing problem report #2466.
|
|
o G4LossFluctuationDummy: new class with zero fluctuations.
|
|
o G4UrbanMscModel: minor optimisation of arithmetics. Removed multiple
|
|
initialisation of the cache data structure and possible data race.
|
|
o G4CoulombScattering: for single scattering used in restricted interval
|
|
of large angles, use 'fEmIncreasing' type of cross-section shape.
|
|
+ utils
|
|
o G4VEmProcess: fixed methods where implementation is based on assumption
|
|
that the lambda table is defined for full energy range:
|
|
LambdaPhysicsVector(..), CrossSEctionPerVolume(..), FindLambdaMax(..).
|
|
No change is expected for the default physics configuration; fix mainly
|
|
affecting positron annihilation processes at high energies.
|
|
o G4VMscModel, G4VEmProcess: move few methods and header files from
|
|
header to source in order to reduce dependencies between packages.
|
|
o G4EmParametersMessenger: added forgotten UI command to enable
|
|
polarisation.
|
|
o Added info in 'setMaxBetaChange' command description.
|
|
+ xrays
|
|
o Fix in 'MaxBetaChange' value in Cerenkov process.
|
|
Addressing problem report #2456.
|
|
o G4Scintillation: removed unused 'YieldFactor' declarations.
|
|
Addressing problem report #2470.
|
|
|
|
o Processes - Generic:
|
|
-------------------
|
|
+ cuts
|
|
o G4VRangeToEnergyConverter: fixed construction/destruction of static
|
|
data.
|
|
+ optical
|
|
o Removed G4lrint/G4lint to calculate angle bin for Davis/LBNL LUT;
|
|
fixes crash when angle = 0.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ cross_sections
|
|
o G4ComponentAntiNuclNuclearXS: correct treatment of the cross-sections
|
|
of light anti-nuclei on hydrogen target. This relies on the isospin
|
|
symmetry assumption, according to which the properties of the reactions
|
|
between anti-proton and light nuclei are equivalent to those between
|
|
light anti-nuclei and hydrogen.
|
|
+ models/coherent_elastic
|
|
o G4AntiNuclElastic: correction in SampleInvariantT() method of the
|
|
highest momentum transfer (which was causing the cosine of the polar
|
|
angle in the center-of-mass system to be larger than 1 in some cases).
|
|
Addressing problem report #2204.
|
|
+ models/inclxx
|
|
o G4INCLXXInterface: fixed treatment of kaon0, anti_kaon0, kaon0L, and
|
|
kaon0S. In current reference physics lists, INCLXX is never used for
|
|
handling kaons, although it is capable of doing so, but at process-
|
|
level or in custom physics lists one could observe crashes when trying
|
|
to use INCLXX for neutral kaon projectiles. The change fixes this
|
|
misbehavior.
|
|
|
|
o Run
|
|
---
|
|
+ Fixed missing 'AnnihToTauTau' entry from default physics list ordering
|
|
that would cause a fatal exception if 'EmExtra' is used with
|
|
PositronToMuMu=True.
|
|
+ Adding verbosity control to some printouts to standard output.
|
|
Addressing problem report #2397.
|
|
|
|
o Tasking
|
|
-------
|
|
+ Fixing number of seeds to be generated for the case when seeds from
|
|
master are seeded only once per task.
|
|
+ Adding verbosity control to some printouts to standard output.
|
|
Addressing problem report #2397.
|
|
|
|
o Examples:
|
|
--------
|
|
+ extended/medical/fanoCavity
|
|
+ extended/medical/fanoCavity2
|
|
o Make PhysicsLists coherent with main physics_list library.
|
|
+ extended/optical/OpNovice
|
|
o Fixed incorrect call to G4MaterialPropertiesTable::AddProperty().
|
|
Added comments explaining use.
