Geant4 10.0 - patch-04 Release Notes
|
|
------------------------------------
|
|
|
|
6 March 2015
|
|
|
|
List of fixes included in this public patch since the public release 10.0.p03:
|
|
|
|
o Geometry:
|
|
--------
|
|
+ navigation:
|
|
o G4Navigator: corrections in the computation of exit normal and small
|
|
fix to calculation of stored step endpoint, for steps that do not hit
|
|
a boundary. Some code cleanup.
|
|
o Added protection in G4ReplicaNavigation::DistanceToOutRad() for
|
|
potential rare cases of negative value to sqrt() in equation
|
|
calculation for rmin/rmax intersection.
|
|
o G4ErrorPropagationNavigator: added GetGlobalExitNormal() method to
|
|
match the update of G4Navigator interface made back in release 9.5.
|
|
Fix to make normal a unit vector, and fixed Coverity defect to protect
|
|
against null 'target'. Revised implementation of ComputeStep(),
|
|
to avoid calling G4Navigator::ComputeSafety().
|
|
Addresses problem report #1679.
|
|
+ solids/CSG:
|
|
o Fixed typo in copy-ctor and assignment operator for G4Tubs and G4OTubs.
|
|
o Fix in temporary class G4OTubs to include symbol in library in any case.
|
|
+ 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 Added special DistanceAway() method for Inside() in order to fix
|
|
precision problem in calculation of DistanceToSide() in G4PolyconeSide.
|
|
o Fix in SetOriginalParameters() for G4Polycone and G4Polyhedra, in case
|
|
of presence of 'rings' structures. Addressing problem report #1705.
|
|
o Use canonical form for operator=() in G4PolyconeHistorical and
|
|
G4PolyhedraHistorical.
|
|
+ solids/usolids:
|
|
o UPolycone: correction in Capacity() for iteration over the number of
|
|
sections and in SurfaceArea() in case opening-angle is less than 2*pi.
|
|
Fixes in InsideSection() for openPhi when StartPhi is negative,
|
|
in Init() for Polycone defined from ZPlane[0]>ZPlane[N],
|
|
and in DistanceToOut() for points starting on internal surface.
|
|
Fix in InsideSection() for points(0,0,z).
|
|
Fix in SetOriginalParameters(), in case of presence of 'rings'
|
|
structures constructed by (r,z) corners.
|
|
Use canonical form for operator=(). Code cleanup and formatting.
|
|
o Added special DistanceAway() method for Inside() in order to fix
|
|
precision problem in calculation of DistanceToSide() in UPolyconeSide.
|
|
o Fixed typo in copy-ctor and assignment operator for UTubs.
|
|
o UPolyhedra: moved Extent() from protected to public.
|
|
o UTet: fixed approximation in Extent().
|
|
o Minor fixes of errors reported by Coverity and unit tests in
|
|
UTubs,UCons, UTet.
|
|
o Removed useless 'inline' specification for pure virtual function
|
|
StreamInfo() in VUSolid base class.
|
|
o Renamed ExceptionSeverity struct to UExceptionSeverity in UUtils to
|
|
avoid possible clashes with external libraries.
|
|
+ volumes:
|
|
o Avoid post-increment in G4NavigationLevelRep::AddAReference().
|
|
|
|
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 G4Transportation, G4CoupledTransportation: in AlongStepGetPIL(),
|
|
initialize restMass with G4DynamicParticle (as is used in DoIt()),
|
|
not with G4ParticleDefinition. Resolves inconsistent kinematics
|
|
when dynamic mass is measurably different from "PDG" mass.
|
|
|
|
o Global:
|
|
------
|
|
+ G4FPEDetection.hh: restrict FPE trapping to GCC only, excluding CLang.
|
|
Addresses problem with Qt generating an apparent FPE deep inside its
|
|
code with MacOSX CLang builds.
|
|
Added call to 'sigfillset' to clear any signals before any use of
|
|
sigset_t in InvalidOperationDetection() for both MacOS and Linux, as
|
|
suggested in specifications.
|
|
+ Added missing G4GLOB_DLL specification for DLL import/export to
|
|
G4CacheDetails specialization of cache reference for double.
|
|
+ Updated date and version for 10.0.p04.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ 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 Physics Lists:
|
|
-------------
|
|
+ constructors/hadron_inelastic:
|
|
o Added protection in destructors to avoid double deletes.
|
|
+ constructors/limiters:
|
|
o Fix in G4ParallelWorldProcess to correctly use method
|
|
SetProcessOrderingToSecond().
|
|
+ lists:
|
|
o INCLXXPhysicsListHelper: avoid use of G4NeutronTrackingCut
|
|
for *_HP physics-lists.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ management:
|
|
o G4HadronicProcess::CheckResult(): added check for dynamic mass
|
|
to correspond to PDG mass within ~10%.
|
|
+ models/cascade:
|
|
o G4CascadeInterface: fixed possible infinite-loop condition where
|
|
(nTries >= maxTries) and momentum balance fails.
|
|
+ stopping:
|
|
o G4HadronStoppingProcess, G4MuonMinusBoundDecay: fixed time of muon
|
|
nuclear capture secondaries. Addressing problem report #1695.
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
