|
o Added settings for C++ standards in platform specific scripts.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ Fixed definition of /analysis/ntuple command directory which was created
|
|
implicitly with the commands and so defined without a guideline and not
|
|
deleted.
|
|
|
|
o Externals
|
|
---------
|
|

|
|
Addressing problem report #1831.
|
|
+ navigation:
|
|
o Relaxed condition for zero or almost-zero steps in G4ReplicaNavigation
|
|
and G4Navigator, to allow for faster progression in case of stuck tracks
|
|
in 3D scoring meshes. Addressing old problem report #1432.
|
|

|
|
Addressing problem report #1809.
|
|
Disabled debug warning in SurfaceNormal().
|
|
o Correction in G4ExtrudedSolid::AddGeneralPolygonFacets() for precision
|
|
treatment in construction of tessels to avoid cases of collinear points
|
|
and consequent degenerating triangles.
|
|
Addressing problem report #1777.
|
|
o Use pre-computed kCarToleranceHalf constant in G4ExtrudedSolid, now
|
|
protected in G4TessellatedSolid.
|
|
|
|
o Global:
|
|
------
|
|
+ Corrected conditions for proper treatment of gcc-5 in tls.hh and
|
|
G4Threading.hh.
|
|
+ Removed unused and buggy operator=(const G4String&) in G4SubString.
|
|
+ Updated date and version for 10.2.p01.
|
|
|
|
o Graphics Representations:
|
|
------------------------
|
|
+ Use "" instead of <> for internal header inclusion in
|
|
HepPolyhedronProcessor.h.
|
|
|
|
o Materials:
|
|
---------
|
|
+ Fixed rare data-race in G4MaterialPropertiesTable for optical physics.
|
|
+ G4NistMaterialBuilder: added lock to build of new NIST material; needed,
|
|
as some physics processes may create a new NIST material from worker
|
|
thread.
|
|
+ G4NistElementBuilder: fixed typo in printout.
|
|
Addressing problem report #1786.
|
|
|
|
o Particles:
|
|
---------
|
|
+ Fixed wrong argument order CreateIon(A,Z,LL,0.0) in G4IonTable to
|
|
CreateIon(Z,A,LL,0.0).
|
|
+ Fixed setting of mass in decay parent particle.
|
|
Addressing problem report #1820.
|
|
+ Fixed G4DecayTable::SelectADecayChannel() for decay channels all
|
|
kinematically forbidden.
|
|
+ In G4IonTable removed static const tolerance and replaced with call to
|
|
G4NuclideTable; this recovers missed levels when they are closer together
|
|
than 2 keV. Reverted default value of level tolerance in G4NuclideTable
|
|
to 1 eV; turn out rounding of excitation energy to avoid potential
|
|
conservation problems.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ GDML:
|
|
o Corrected broken URLs and version number to schema.
|
|
|
|
o Physics Lists
|
|
-------------
|
|
+ builders:
|
|
o G4NeutronHPBuilder: corrected name from "NeutronHPInelastic" to
|
|
"ParticleHPInelastic".
|
|
+ constructors/limiters:
|
|
o G4ParallelWorldPhysics: fixed process order index for
|
|
G4ParallelWorldProcess to 9900 to make sure it is registered
|
|
prior to G4OpBoundaryProcess.
|
|
+ constructors/electromagnetic:
|
|
o G4EmStandardPhysicsSS: do not compute cross-section tables
|
|
if experimental Mott cross-section is enabled (this provides a
|
|
significant increase in CPU, but only in this conditions Mott
|
|
corrections are valid).
|
|
+ constructors/hadron_elastic:
|
|
o Added missing hadron elastic for He3 in G4HadronElasticPhysics,
|
|
using Glauber-Gribov elastic cross-section (Gheisha does not have
|
|
hadronic - elastic and inelastic - cross-sections for He3).
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ dna:
|
|
o In ionisation models SampleSecondaries(), added protection on energy
|
|
in case of interpolation method change.
|
|
+ lowenergy:
|
|
o Fixed inclusion guard in G4LivermorePolarizedPhotoElecticModel.hh.
|
|
Addressing problem report #1816.
|
|
o Code cleanup and fixed Coverity defects.
|
|
+ standard:
|
|
o Fixed cases of floating-point exception in G4ScreeningMottCrossSection.
|
|
Some code cleanup and performance improvements.
|
|
o Fixed sampling of scattering angle in G4eSingleCoulombScatteringModel.
|
|
Addressing problem report #1823.
|
|
o G4GoudsmitSaundersonMscModel G4GoudsmitSaundersonTable: updated step
|
|
limitations. Fixed Coverity defects and improved comments.
|
|
+ utils:
|
|
o G4EmSaturation: corrected method name from VisibleEnergyDeposition() to
|
|
VisibleEnergyDepositionAtAStep(), in order to allow overloading of
|
|
virtual method. Addressing problem report #1807.
|
|
o G4EmCalculator: fixed computation of dEdx and range for He3 and alpha.
|
|
Addressing problem report #1808.
|
|
o G4LossTableManager: avoid double addition of He3 and alpha to the loss
|
|
table map (should not have any effect on results).
|
|
+ xrays:
|
|
o G4VTransitionRadiation, G4VXTRenergyLoss: fixed process sub-type.
|
|
o G4Scintillation: use new method introduced in G4EmSaturation
|
|
VisibleEnergyDepositionAtAStep() in order to fix overloading problem.
|
|
|
|
o Processes - Generic:
|
|
-------------------
|
|
+ biasing:
|
|
o Code cleanup and Coverity fixes in 'generic' and 'management' modules.
|
|
+ scoring:
|
|
o G4ParallelWorldProcess: fixed processType from 'fParameterized'
|
|
to 'fParallel' and set processSubType to 491.
|
|
+ optical:
|
|
o Fix to DielectricLUT concerning the sequence of rotations.
|
|
Addressing problem report #1826.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ models/abla:
|
|
o Fixed bug in de-excitation of boosted nucleon remnants.
|
|
+ models/de_excitation:
|
|
o G4GammaTransition: added protection against rare problem in sampling
|
|
of internal conversion when transition energy is lower than atomic
|
|
level energy: instead of stopping the cascade, set bound level energy
|
|
to zero and produce final e-; this allows to complete radioactive-decay
|
|
cascade. Addressing problem report #1806.
|
|
o G4PhotonEvaporation, G4LevelManager, G4LevelReader, G4NuclearLevelData:
|
|
fixed remaining cases of production of excited stated.
|
|
Addressing problem report #1806.
|
|
o G4PhotonEvaporation, G4LevelReader, G4NucLevel: fixed treatment of
|
|
X-levels (meta-stable nuclear levels which have forbidden gamma
|
|
transition but opened beta-transitions); this fix excludes creation of
|
|
very low-energy fake gamma and provides a correct nuclear decay
|
|
sequence.
|
|
o G4PhotonEvaporation: set limit on emitted gamma energy 0.1 keV (was
|
|
10 keV).
|
|
+ models/lend:
|
|
o Fixed problem in prodcution of residual neutrons.
|
|
o Corrected use of isnan() to std::isnan() for compilers different than
|
|
Windows/VC++.
|
|
o Fixed Coverity defects.
|
|
+ models/particle_hp:
|
|
o Fixes for problem on materials with hydrogen or helium.
|
|
o Fixed problems in deletion of cross-section data set in MT mode
|
|
and initialisation of cached data.
|
|
o Fixed Coverity defects.
|
|
+ models/qmd:
|
|
o Fixed bug in handling forbidden decay in G4QMDCollision.
|
|
+ models/radioactive_decay:
|
|
o G4BetaMinusDecay, G4RadioactiveDecay: added protection for case
|
|
when end point energy is 0 in beta- decay.
|
|
Addressing problem report #1766.
|
|
+ models/util:
|
|
o G4KineticTrack: replaced G4cerr with a 'JustWarning' G4Exception.
|
|
+ util:
|
|
o G4Nucleus: increased the max number of loops allowed in the method
|
|
GetBiasedThermalNucleus().
|
|
|
|
o Run:
|
|
---
|
|
+ G4PhysicsListHelper: added entry for G4ParallelWorldProcess.
|
|
+ G4RunManager, G4WorkerRunManager: fixed process order index of
|
|
G4ParallelWorldProcess to 9900 to make sure it is registered
|
|
prior to G4OpBoundaryProcess.
|
|
|
|
o Tracking:
|
|
--------
|
|
+ G4SteppingManager: fix to properly set 'OriginTouchableHandle' for the
|
|
primary track. Addressing problem report #1773.
|
|
|
|
o Data sets:
|
|
---------
|
|
+ Patched data set for nuclides properties G4ENSDFSTATE-1.2.1:
|
|
o Added missing data for RA228, SI24, SI25 and 193RN.
|
|
+ Patched data set for radioactive-decay, G4RadioactiveDecay-4.3.1:
|
|
o Replace NaN values for intensity by 1 in z71.a157(Lu157),
|
|
z55.a136(Cs136) and z59.a129(Pr129).
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
|
|
+ basic:
|
|
o Added G4ENSDFSTATEDATA in the lists of mandatory data sets; updated
|
|
README files. Addressing problem report #1810.
|
|
o B4: restored the third parameter in G4UIsession construction, which
|
|
was lost when moving G4UIExecutive at the beginning of main().
|
|
Addressing problem report #1802.
|
|
+ extended/biasing/B03:
|
|
o B03PhysicsList: corrected process order index of G4ParallelWorldProcess
|
|
to 9900 to make sure it is registered prior to G4OpBoundaryProcess.
|
|
+ extended/electromagnetic:
|
|
o Fixed macros to allow to work both with Root-5 and 6.
|
|
+ extended/radioactivedecay/rdecay01:
|
|
o PhysicsList: SetLevelTolerance to 1*eV, there appears to already be a
|
|
level Ni60[1332.510] stored somewhere instead of Ni60[1332.514].
|
|
Setting the tolerance to 1 eV gets the right level.
|
|
o Improved printout in Run::EndOfRun().
|
|
o Updated references in it1.mac and it2.mac.
