Geant4 9.6 - patch-01 Release Notes
|
||||
-----------------------------------
|
||||
|
||||
1 February 2013
|
||||
|
||||
List of fixes included in this public patch since the public release 9.6:
|
||||
|
||||
o Event:
|
||||
-----
|
||||
+ Fixed missing deletion of UI command in destructor of G4StackMessenger.
|
||||
Addressing problem report #1380.
|
||||
|
||||
o Geometry:
|
||||
--------
|
||||
+ navigation:
|
||||
o Cleared left-over debug check in G4VoxelNavigation.
|
||||
Addressing problem report #1406.
|
||||
+ solids/specific:
|
||||
o Fixed cases of hang-ups in G4ExtrudedSolid on 32-bits platforms, due to
|
||||
G4TessellatedSolid and G4SurfVoxelizer, caused by accessing bitmask
|
||||
arrays with negative indexes. The problem was related to floating-point
|
||||
rounding, which can be different even on same platform with
|
||||
debug/release version.
|
||||
Assuring same number of computed voxels on 32-bit/64-bit platforms.
|
||||
Fixed error in SetVertexIndex() method, which might cause problems on
|
||||
certain configurations. Fixed minor memory leaks.
|
||||
Code cleanup for use of G4endl and tabs...
|
||||
o Fixed condition in G4VTwistSurface::GetBoundaryLimit() for logical
|
||||
error. Addressing problem report #1420.
|
||||
|
||||
o Global:
|
||||
------
|
||||
+ Updated date and version for 9.6.p01.
|
||||
|
||||
o Electromagnetic Processes:
|
||||
-------------------------
|
||||
+ High Energy:
|
||||
o G4eeTo3PiModel: removed printout from destructor.
|
||||
Addressing problem report #1404.
|
||||
o G4mplIonisationWithDeltaModel: fixed min and max energy
|
||||
of delta-electron production.
|
||||
+ Low Energy:
|
||||
o G4LivermorePhotoElectricModel: fix addressing problem report #1402.
|
||||
o G4UAtomDeexcitation: removed shortcut when Auger is activated.
|
||||
+ Standard:
|
||||
o Fixed signature of SampleScattering() for all multiple-scattering
|
||||
models. Addressing problem report #1403.
|
||||
o G4UrbanMscModel93, G4UrbanMscModel95, G4UrbanMscModel96: added limit
|
||||
for the main parameter responsible for sampling of scattering tail (fix
|
||||
for ATLAS large scattering angle problem).
|
||||
Use safer expression in SampleCosineTheta() to avoid numerical problems.
|
||||
Extended initialisation at StartTracking() method: class members are
|
||||
reset to default values to avoid rare cases of non-reproducibility.
|
||||
o G4UrbanMscModel96: optimised tuning of Urban model.
|
||||
+ Utils:
|
||||
o G4VMultipleScattering, G4VMscModel: fixed signature of method
|
||||
SampleScattering(). Use momentum direction from PostStepPoint instead
|
||||
of G4DynamicParticle.
|
||||
Fixing major bug of migration of multiple-scattering sampling from
|
||||
PostStepDoIt() to AlongStepDoIt(), responsible for observed
|
||||
mis-behavior in presence of magnetic-field.
|
||||
Addressing problem report #1403.
|
||||
|
||||
o Generic Processes:
|
||||
-----------------
|
||||
+ Transportation:
|
||||
o Corrected condition for warning message in method AlongStepDoIt()
|
||||
of G4Transportation.
|
||||
|
||||
o Hadronic Processes:
|
||||
------------------
|
||||
+ cross_sections:
|
||||
o Fixed memory leak in cross-sections for GetZandACrossSection().
|
||||
Addressing problem report #1424.
|
||||
o Fixed bug to G4ComponentAntiNuclNuclearXS and added class description.
|
||||
Fixed case of non-reproducibility observed with QBBC physics-list:
|
||||
consider anti-protons and anti-neutrons as default particles, so that
|
||||
they can be used also for anti-hyperons.
|
||||
o Fixed several Coverity defects for initialisation of class members.
|
||||
+ models/coherent_elastic:
|
||||
o Fixed conditional statement depending on uninitialised variable.
|
||||
+ models/de_excitation:
|
||||
o Fix in G4ExcitationHandler: if FermiBreakUp returns unchanged
|
||||
fragment then the fragment is decayed by Evaporation instead of
|
||||
PhotonEvaporation to avoid production of non-physical isotopes
|
||||
like 4H.
|
||||
+ models/im_r_matrix:
|
||||
o Fix in G4Scatterer::GetTimeToInteraction(); one shortcut in the
|
||||
calculation of time was missed, as only one of the two particles was
|
||||
checked. Physics unchanged, but small performance gain of few percent.
|
||||
Addressing problem report #1334.
|
||||
+ models/inclxx:
|
||||
o Updated to INCL++ v5.1.9: removed calls to abort() and exit().
|
||||
Addressing problem report #1421.
|
||||
+ models/neutron_hp:
|
||||
o Fixed improper use of abort() in G4NeutronHPThermalScattering.
|
||||
Addressing problem report #1421.
|
||||
+ models/qmd:
|
||||
o Fix for logic error in G4QMDGroundStateNucleus::packNucleons().
|
||||
Addressing problem report #1418.
|
||||
+ models/radioactive_decay:
|
||||
o G4RadioactiveDecay: force boost of the decay products. The parent
|
||||
energy considered in the boost is the total energy of the fully
|
||||
stripped parent ion rather than the total energy of dynamic ion
|
||||
where the energy of shell electrons is taken into account.
|
||||
Some difference in momentum and energy balance is still observed
|
||||
but much less than before. Addressing problem report #1359.
|
||||
|
||||
o Materials:
|
||||
---------
|
||||
+ G4NistMaterialBuilder: fixed stainless steel parameters, taken from
|
||||
http://www.azom.com/article.aspx?ArticleID=965.
|
||||
|
||||
o Physics Lists:
|
||||
-------------
|
||||
+ G4EmStandardPhysics_option4: substituted new low-energy Compton
|
||||
model by old LivermoreCompton model to avoid numerical problems
|
||||
in high statistic runs.
|
||||
|
||||
o Tracking:
|
||||
--------
|
||||
+ Replaced plain printout to cerr with G4Exception warning in
|
||||
G4SteppingManager::InvokeAtRestDoItProcs().
|
||||
Addressing problem report #1421.
|
||||
|
||||
o Examples:
|
||||
--------
|
||||
+ Updated reference outputs.
|
||||
+ advanced/nanobeam:
|
||||
o Corrected order and format of inclusion of CLHEP headers.
|
||||
+ advanced/underground_physics:
|
||||
o Fixed case of missing inclusion of units header when analysis activated.
|
||||
o Make Auger, fluorescence and PIXE on by default.
|
||||
Addressing problem report #1386.
|
||||
+ extended/electromagnetic/TestEm7:
|
||||
o G4ScreenedNuclearRecoil: define type and sub-type of process;
|
||||
removed inlusion of obsolete header
|
||||
o PhysListEmStandardNR: use standard electron ionisation instead
|
||||
of Penelope, use multiple scattering for ions above 100 MeV/u.
|
||||
o PhysListEmStandard: use SetEmModel() method.
|
||||
o RunAction: delete analysis manager and all histograms at the end of run.
|
||||

|
||||
o Removed use of obsolete class G4HadronQElasticPhysics.
|
||||
+ extended/exoticphysics/monopole:

||||
+ solids/CSG:
|
||||
o Fix in G4Cons::DistanceToIn(p,v) for initialisation of 'dRmax'
|
||||
for the case of shape with Rmin1=Rmax1=0.
|
||||
+ solids/specific:
|
||||
o Fix in G4ExtrudedSolid::IsSameLine() to use the perpendicular
|
||||
distance to a line when deciding, and not the y-intercept difference.
|
||||
Issue responsible for a problem observed in ATLAS in a Boolean
|
||||
subtraction composition.
|
||||
o Fix in calculation of normal in G4Tet::DistanceToOut(p,v,..) and

o Fix in G4Polycone::GetPointOnCone() for cases of shape with decreasing
|
||||
Z. Fixes cases of false report for overlaps detection.
|
||||
Added check with exception in constructor for polycone with
|
||||
rInner > rOuter for the same Z.
|
||||
Addressing problem report #1462.
|
||||
o G4TessellatedSolid: fixed problem with navigation in solids with
|
||||
concave surfaces. Addresses problem report #1456.
|
||||
o Removed unused private data member in G4TwistTrapParallelSide.
|
||||
|
||||
o Global:
|
||||
------
|
||||
+ G4Pow: fixed bug in interpolation inside logA() and A13() methods,
|
||||
now interpolation is accurate at better than per mille level; in worse
|
||||
cases (x~1.45 or x~0.75) better than 2% level.
|
||||
+ Minor changes to G4ConvergenceTester: output can now optionally be
|
||||
redirected a different stream (defaults is cout).
|
||||
Accessors are made public and check if data has been added.
|
||||
+ Removed unused private members in G4JTPolynomialSolver.
|
||||
+ Updated date and version for 9.6.p02.
|
||||
|
||||
o Graphics Representations:
|
||||
------------------------
|
||||
+ HepPolyhedron: introduced 'spatialTolerance' constant, equal to 0.01*nm,
|
||||
allowing for creation of nm-sized objects.
|
||||
Addresses problem report #1452.
|
||||
|
||||
o Electromagnetic Processes:
|
||||
-------------------------
|
||||
+ Adjoint:
|
||||
o G4AdjointhMultipleScattering: use msc95 instead of obsolete msc90.
|
||||
o Removed unused variables detected with clang compilation warnings.
|
||||
+ Muons:
|
||||
o G4MuPairProductionModel, G4MuBremsstrahlungModel: fixed rare case
|
||||
of division by zero in cross-section computation.
|
||||
Addressing problem report #1471.
|
||||
+ Polarisation
|
||||
o G4PolarizedComptonCrossSection: removed unused class members.
|
||||
+ Standard:
|
||||
o G4UrbanMscModel93/95/96: disabled 'sampleZ' option by default (this
|
||||
option enables/disables sampling of true step length); helps in
|
||||
removing rare cases of e+- interactions/decay on geometry boundary
|
||||
and observed zero step length; a minor (~0.1%) change in sampling
|
||||
calorimeter response is expected.
|
||||
Correctly use "static const" for const parameters (minor CPU
|
||||
speedup).
|
||||
o G4WentzelOKandVIxSection: use different screening parameter formula
|
||||
for e+- and other charged particles, improving agreement with data
|
||||
both for e+- and muons.
|
||||
|
||||
o Generic Processes:
|
||||
-----------------
|
||||
+ parameterisation:
|
||||
o Fixed MacOS Clang compiler warning for unused private variable in
|
||||
G4FastSimulationManagerProcess.
|
||||
+ Scoring:
|
||||
o Set verbosity to false in G4ParallelWorldProcess for navigation
|
||||
in parallel and mass world, reducing warning messages.
|
||||
+ Transportation:
|
||||
o G4CoupledTransportation: corrected condition for warning message
|
||||
in AlongStepDoIt().
|
||||
o G4CoupledTransportation, G4Transportation: removed unnecessary
|
||||
static local variables.
|
||||
o Removed unused data members causing compilation warnings in
|
||||
MacOS clang.
|
||||
|
||||
o Hadronic Processes:
|
||||
------------------
|
||||
+ cross_sections:
|
||||
o G4HadronFissionDataSet: always return zero (only HP may simulate
|
||||
fission as a separate process).
|
||||
+ models/im_r_matrix:
|
||||
o Fix in G4MesonAbsorption for loss of optimisation shortcut.
|
||||
Addressing problem report #1416.
|
||||
o Fix in G4CollisionMesonBaryonElastic::IsInCharge(): method always
|
||||
returned false, effectively blocking meson-baryon elastic.
|
||||
Expect to change distributions. Addressing problem report #1415.
|
||||
+ models/lll_fission:
|
||||
o Fixed MacOS Clang compiler warning for appending int to string
|
||||
in G4SmpWatt.
|
||||
+ models/neutron_hp:
|
||||
o Fixed MacOS clang compiler warnings for unused private variables.
|
||||
+ models/parton_string/diffraction:
|
||||
o Fix in G4FTFModel::PutOnMassShell() for K^+ Fe interactions at
|
||||
T=4.6748 GeV, resolving observed cases of loops in central collision
|
||||
due to sum of the excitation energy and energies of the ejected
|
||||
nucleons larger than the initial energy (energy-momentum
|
||||
non-conservation). Addressing problem report #1459.
|
||||
+ models/qmd:
|
||||
o Fixed MacOS Clang compiler warnings for unused private variables in
|
||||
G4QMDCollision.
|
||||
+ models/utils:
|
||||
o G4NuclearFermiDensity: removed unused data member.
|
||||
+ stopping:
|
||||
o G4EmCaptureCascade: fixed array initialisation.
|
||||
o G4MuonMinusBoundDecay: improved muon capture rate data/lookup and
|
||||
calculation of bound muon decay rate.
|
||||
Corrected calculations and lookup of MuonCaptureRate in
|
||||
G4StopElementSelector. Addresses problem report #1457.
|
||||
|
||||
o Parameterisations/gflash
|
||||
------------------------
|
||||
+ Fixed compilation warning in clang for unused data member in
|
||||
GFlashShowerModelMessenger.

||||
+ gdml:
|
||||
o Removed unused data member in G4STRead.
|
||||
+ mctruth:
|
||||
o Removed unused data member in G4PersistencyCenter.
|
||||
|
||||
o Physics Lists:
|
||||
-------------
|
||||
+ Increased low limit from 10 eV to 100 eV in G4EmStandardPhysics_option4,
|
||||
to fix range of electrons at low energy.
|
||||
+ G4EmLivermorePhysics: increased low limit to 100 eV and number of bins
|
||||
for tables to 220 to avoid problems in Livermore ionisation for
|
||||
electron stopping powers and ranges.
|
||||
|
||||
o Track:
|
||||
-----
|
||||
+ Fix in G4ParticleChange for velocity of neutrons and recoil in elastic
|
||||
scattering; correspondingly, fixed time of neutron hits in calorimeters.
|
||||
Addressing problem report #1451.
|
||||
+ G4ParticleChangeForEloss, G4ParticleChangeForGamma: clean up
|
||||
computation of velocity (expected little performance improvement).
|
||||
|
||||
o Tracking:
|
||||
--------
|
||||
+ Fix in G4SteppingManager to allow for proper handling of multiple AtRest
|
||||
processes. Addressing problem report #1397.
|
||||
|
||||
o Examples:
|
||||

|
||||
+ Updated reference outputs.
|
||||
+ advanced/composite_calorimeter:
