0002 Geant4 6.2 - patch-02 Release Notes
0003 -----------------------------------
0004
0005 26 October 2004
0006
0007 List of fixes included in this public patch since release 6.2-patch-01:
0008
0009 o Geometry:
0010 --------
0011 + divisions:
0012 o Removed unnecessary debug printout in method
0013 G4PVDivision::CheckAndSetParamenters().
0014 + management:
0015 o G4Region: added map for storage of materials/cuts and methods for
0016 handling registration of couples in the map, finding a couple
0017 according to a given material, clearing the map's storage.
0018 Extensions necessary to resolve correct update of material-cut
0019 couples in parameterised geometries by material.
0020 o G4LogicalVolume: added method UpdateMaterial() to refresh a
0021 material/cut couple in the corresponding region.
0022 Extension necessary to resolve correct update of material-cut
0023 couples in parameterised geometries by material.
0024 o Fixed G4RegionStore::Clean() to avoid deletion of world region.
0025 + navigation:
0026 o G4Navigator: corrected computation of fGrandMotherExitNormal in
0027 ComputeStep() in the case where a not valid exit-normal exists.
0028 o G4GeomTestSegment: fix to correctly determine whether starting
0029 trajectory is entering or exiting the solid when the starting point
0030 is on a surface. Added additional tests on solid consistencies
0031 (from roundoff sometimes) to avoid incorrect overlap warnings.
0032 Addresses problem reports #610 and #652.
0033 o Dump out contents from the solid when a fatal G4Exception is thrown
0034 from the navigators in ComputeStep().
0035 o Invoke G4LogicalVolume::UpdateMaterial() instead of SetMaterial()
0036 for parameterised navigation in G4Navigator and specialised
0037 G4ParameterisedNavigation.
0038 Modification necessary to resolve correct update of material-cut
0039 couples in parameterised geometries by material.
0040 + solids/CSG:
0041 o Fix in G4Cons::DistanceToIn(p,v) on fRmax surface and move in,
0042 the condition became a bit more strict && determinant >=0, i.e.
0043 intersections in addition to go in.
0044 Fixes a rare problem of dIn=dOut=0 observed in 3 events over a
0045 statistics of 10^8..
0046 o Fix in G4Sphere::DistanceToOut(p,v,...) on fRmin moving outside.
0047 The bug showed 3 events of dIn=dOut=0 for 10^7 statistics in the
0048 unit testing.
0049 o Bug fix in G4Sphere::SurfaceNormal(p) for theta normals.
0050 + solids/specific:
0051 o G4VCSGfaceted: fix for rare anomalous situation in which
0052 DistanceToOut(p,v,..) will report kInfinity, make an additional
0053 check for the point p on the surface, in which case will report
0054 zero. Addresses problem observed in G4Polyhedra and reported in #650.
0055
0056 o Materials:
0057 ---------
0058 + Added protection in G4AtomicShells::GetNumberOfShells(Z).
0059 Fixes problem report #643.
0060 + Recalculate ionisation parameters after set of new mean ionisation
0061 potential; added factor 2 to shell correction term.
0062
0063 o Processes/cuts:
0064 --------------
0065 + Fixed bug in G4ProductionCutsTable for the update of materials/cuts
0066 couple for dynamic setups where material may vary, like in the case
0067 of parameterization of detectors through material.
0068
0069 o Electromagnetic processes:
0070 -------------------------
0071 + lowenergy:
0072 o Trivial fixes for removal of redundant semicolons in the code.
0073 + utils:
0074 o Fixed a problem of cut dependence of transmission energy of low
0075 energy e- via thin foil
0076 + xrays:
0077 o Changed "StronglyForced" back to "Forced" in GetMeanLifeTime() for
0078 the G4Scintillation process.
0079
0080 o Hadronic Processes:
0081 ------------------
0082 + models/cascade:
0083 o Fixed bug in G4CascadeInterface for uncorrect deletion of dynamic
0084 particles. Fixes problem report #645.
0085
0086 o Optical Processes:
0087 -----------------
0088 + Allow for unified model reflectivity parameters to also work in case
0089 of dielectric_metal surfaces; in G4OpBoundaryProcess, use GetMaterial()
0090 from G4StepPoint directly, sample reflectivity and apply unified model
0091 reflection parameters only once even for rough dielectric/metal
0092 surfaces. Fixes problem report #654.
0093 + Fixed bug in G4PlaneVectorRand for G4OpBoundaryProcess and resample
0094 'theFacetNormal' for LobeReflection in DielectricMetal.
0095
0096 o Run:
0097 ---
0098 + Updated date to run-manager.
0099
0100 o Visualization:
0101 -------------
0102 + OpenGL: G4OpenGLTransform3D.cc: simplified implementation for
0103 GetMatrix() to allow for porting on future CLHEP series.
0104
0105 o Examples:
0106 --------
0107 + Updated reference outputs.
0108 + electromagnetic/MuonProcesses
0109 o Modified HistoManager and Messenger in order to allow a multirun job.
0110 + electromagnetic/PhotonProcesses
0111 o Modified HistoManager and Messenger in order to allow a multirun job.
0112 + electromagnetic/TestEm2
0113 o Updated acceptance numbers in input macro.
0114 o Fixed problem in initialisation of RunAction.
0115 + electromagnetic/TestEm4
0116 o Modifications in RunAction for histograms management for JAIDA.
0117 + electromagnetic/TestEm6
0118 o Correctly defined all UI subdirectories.
0119 o Modifications in RunAction for histograms management for JAIDA.
0120 + electromagnetic/TestEm10
0121 o Removed obsolete processes from PhysicsList.
0122 + extended/field
0123 o Minor cleanup of PhysicsLists.
0124 + extended/optical
0125 o Fixed compilation error and warnings for LXe on Linux/gcc compiler.
0126 + novice/N05
0127 o Added protection for negative proposed step in ExN05MinEkineCuts.
