Geant4 9.6 - patch-04 Release Notes
|
|
-----------------------------------
|
|
|
|
30 January 2015
|
|
|
|
List of fixes included in this public patch since the public release 9.6.p03:
|
|
|
|
o Geometry:
|
|
--------
|
|
+ navigation:
|
|
o G4Navigator: corrected saving/restoring of 'navigator state'.
|
|
o G4PathFinder: added EndTrack() method, to reset internal state
|
|
and inform G4TransportationManager to use 'ordinary' Navigator.
|
|
o Fix in G4MultiNavigator to properly set 'fIdNavLimiting' index to
|
|
navigator limiting the step, if only one navigator limits the step.
|
|
+ solids/specific:
|
|
o Fixed triangularisation method AddGeneralPOlygoneFacets() in
|
|
G4ExtrudedSolid by avoiding flat triangles. Added warning message to
|
|
G4TriangularFacet constructor if Area is 0; i.e., case of flat triangle.
|
|
Addressing problem report #1703.
|
|
o Get rid of deprecated 'register' storage class specifier in source files.
|
|
+ volumes
|
|
o Avoid post-increment in G4NavigationLevelRep::AddAReference().
|
|
|
|
o Global:
|
|
------
|
|
+ Fix in G4SimplexDownhill header to proper define header guard.
|
|
+ Updated date and version for 9.6.p04.
|
|
|
|
o Generic Processes:
|
|
-----------------
|
|
+ Management:
|
|
o Fixed logic in G4ProcessManager::SetProcessOrderingToSecond() to make
|
|
sure the process is always set before the process that has ordering
|
|
index 1.
|
|
+ Transportation:
|
|
o Fix in G4CoupledTransportation to message G4PathFinder for resetting
|
|
to the default navigator as the 'standard' Mass navigator at end of
|
|
tracking. Avoid use of multi-navigator when it should not be used.
|
|
o Fix in G4Transportation to save pointer to particle change as required
|
|
by G4VProcess interface.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ management:
|
|
o G4HadronicProcess::CheckResult(): added check for dynamic mass
|
|
to correspond to PDG mass within ~10%.
|
|
+ models/binary_cascade:
|
|
o G4BinaryCasacde: improved calculation of mass, and of correction for
|
|
outgoing particles by always using GetIon() method; addresses potential
|
|
crash for p+d seen in d+H in BIC.
|
|
o G4{Proton,Neutron}Field: protect against negative index into buffer.
|
|
+ models/cascade:
|
|
o G4CascadeInterface: fixed possible infinite-loop condition where
|
|
(nTries >= maxTries) and momentum balance fails.
|
|
o G4InuclNuclei: fix case of floating-point exception in
|
|
setExcitationEnergy() for zero Ekin.
|
|
o Fix for memory leak in secondaries in G4IntraNucleiCascader.
|
|
Addressing problem report #1584.
|
|
+ models/parton_string:
|
|
o Fix for rare crash in G4LundStringFragmentation in the case of
|
|
anti-sigma+ capture at rest on hydrogen.
|
|
+ stopping:
|
|
o G4MuMinusCapturePrecompound: added simplified model for capture in
|
|
deuterium and in He4; reduced number of trials to find neutrino
|
|
4-momentum from 1000 to 100; added protection 1 keV for negative
|
|
excitation energy, and substituted FatalException by JustWarning.
|
|
Addressing rare cases of infinite loop reported by ATLAS.
|
|
o G4AntiProtonAnnihilationAtRest: fixed bug related to a wrong target
|
|
sampling (always the last element of the element vector was sampled
|
|
as target).
|
|
o G4HadronStoppingProcess, G4MuonMinusBoundDecay: fixed time of muon
|
|
nuclear capture secondaries. Addressing problem report #1695.
|
|
o Fix for Coverity defects in G4MuonMinusCaptureAtRest.
|
|
|
|
o Intercoms:
|
|
---------
|
|
+ G4GenericMessenger: fixed case of core dump when GetCurrentValue()
|
|
method is invoked for a command defined by DeclareMethod().
|
|
+ Corrected inclusion protection flag in G4GenericMessenger.hh.
|
|
Addressing old problem report #1527.
|
|
+ Fixed treatment of double-quotes in G4UImanager::ForeachS().
|
|
Addressing problem report #1614.
|
|
|
|
o Interfaces:
|
|
----------
|
|
+ Explicitly set the LC_NUMERIC locale to "C" in G4Qt.
|
|
Addressing problem report #1487.
|
|
Fixed problem with resizing the QGLwidget when scene is opened from UI.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ ascii:
|
|
o Corrected dump of 'phi' and 'theta' for G4Trap and G4Para in dumper.
|
|
Addressing problem report #1602.
|
|
+ gdml:
|
|
o Fixed typo in G4GDMLWriteSolids::BooleanWrite() for the case of repeated
|
|
displacements of the reference solid in the same Boolean operation (issue
|
|
reported by ATLAS).
|
|
o Correction to G4GDMLReadMaterials::MixtureRead() to revert order of
|
|
reading (first elements then materials) for mixtures by fraction;
|
|
corrects referencing for cases when elements and materials may carry
|
|
the same name (case reported by ATLAS).
|
|
o Correction to G4GDMLRead::Read() for the case when schema validation
|
|
is turned off, to disable initialisation of validation machinery in the
|
|
parser and allow for standalone parsing off-network.
|
|
Added better description to fatal exception in case document content
|
|
imported happens to be empty in G4GDMLRead::Read().
|
|
o Corrected minor Coverity defect in G4GDMLParser for uninitialised
|
|
'strip' flag in constructors.
|
|
o Corrected potential memory leak in G4GDMLReadSolids.
|
|
o Corrected dump of 'phi' and 'theta' for G4Trap and G4Para in writer.
|
|
Addressing problem report #1602.
|
|
o Get rid of deprecated 'register' storage class specifier in source files.
|
|
o Added comparison operator for 3-vector key in 'vertexMap' in
|
|
G4GDMLWriteSolids for export of tessellated solid.
|
|
Addressing problem report #1573.
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
