Geant4 6.2 - patch-02 Release Notes
|
|
-----------------------------------
|
|
|
|
26 October 2004
|
|
|
|
List of fixes included in this public patch since release 6.2-patch-01:
|
|
|
|
o Geometry:
|
|
--------
|
|
+ divisions:
|
|
o Removed unnecessary debug printout in method
|
|
G4PVDivision::CheckAndSetParamenters().
|
|
+ management:
|
|
o G4Region: added map for storage of materials/cuts and methods for
|
|
handling registration of couples in the map, finding a couple
|
|
according to a given material, clearing the map's storage.
|
|
Extensions necessary to resolve correct update of material-cut
|
|
couples in parameterised geometries by material.
|
|
o G4LogicalVolume: added method UpdateMaterial() to refresh a
|
|
material/cut couple in the corresponding region.
|
|
Extension necessary to resolve correct update of material-cut
|
|
couples in parameterised geometries by material.
|
|
o Fixed G4RegionStore::Clean() to avoid deletion of world region.
|
|
+ navigation:
|
|
o G4Navigator: corrected computation of fGrandMotherExitNormal in
|
|
ComputeStep() in the case where a not valid exit-normal exists.
|
|
o G4GeomTestSegment: fix to correctly determine whether starting
|
|
trajectory is entering or exiting the solid when the starting point
|
|
is on a surface. Added additional tests on solid consistencies
|
|
(from roundoff sometimes) to avoid incorrect overlap warnings.
|
|
Addresses problem reports #610 and #652.
|
|
o Dump out contents from the solid when a fatal G4Exception is thrown
|
|
from the navigators in ComputeStep().
|
|
o Invoke G4LogicalVolume::UpdateMaterial() instead of SetMaterial()
|
|
for parameterised navigation in G4Navigator and specialised
|
|
G4ParameterisedNavigation.
|
|
Modification necessary to resolve correct update of material-cut
|
|
couples in parameterised geometries by material.
|
|
+ solids/CSG:
|
|
o Fix in G4Cons::DistanceToIn(p,v) on fRmax surface and move in,
|
|
the condition became a bit more strict && determinant >=0, i.e.
|
|
intersections in addition to go in.
|
|
Fixes a rare problem of dIn=dOut=0 observed in 3 events over a
|
|
statistics of 10^8..
|
|
o Fix in G4Sphere::DistanceToOut(p,v,...) on fRmin moving outside.
|
|
The bug showed 3 events of dIn=dOut=0 for 10^7 statistics in the
|
|
unit testing.
|
|
o Bug fix in G4Sphere::SurfaceNormal(p) for theta normals.
|
|
+ solids/specific:
|
|
o G4VCSGfaceted: fix for rare anomalous situation in which
|
|
DistanceToOut(p,v,..) will report kInfinity, make an additional
|
|
check for the point p on the surface, in which case will report
|
|
zero. Addresses problem observed in G4Polyhedra and reported in #650.
|
|
|
|
o Materials:
|
|
---------
|
|
+ Added protection in G4AtomicShells::GetNumberOfShells(Z).
|
|
Fixes problem report #643.
|
|
+ Recalculate ionisation parameters after set of new mean ionisation
|
|
potential; added factor 2 to shell correction term.
|
|
|
|
o Processes/cuts:
|
|
--------------
|
|
+ Fixed bug in G4ProductionCutsTable for the update of materials/cuts
|
|
couple for dynamic setups where material may vary, like in the case
|
|
of parameterization of detectors through material.
|
|
|
|
o Electromagnetic processes:
|
|
-------------------------
|
|
+ lowenergy:
|
|
o Trivial fixes for removal of redundant semicolons in the code.
|
|
+ utils:
|
|
o Fixed a problem of cut dependence of transmission energy of low
|
|
energy e- via thin foil
|
|
+ xrays:
|
|
o Changed "StronglyForced" back to "Forced" in GetMeanLifeTime() for
|
|
the G4Scintillation process.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ models/cascade:
|
|
o Fixed bug in G4CascadeInterface for uncorrect deletion of dynamic
|
|
particles. Fixes problem report #645.
|
|
|
|
o Optical Processes:
|
|
-----------------
|
|
+ Allow for unified model reflectivity parameters to also work in case
|
|
of dielectric_metal surfaces; in G4OpBoundaryProcess, use GetMaterial()
|
|
from G4StepPoint directly, sample reflectivity and apply unified model
|
|
reflection parameters only once even for rough dielectric/metal
|
|
surfaces. Fixes problem report #654.
|
|
+ Fixed bug in G4PlaneVectorRand for G4OpBoundaryProcess and resample
|
|
'theFacetNormal' for LobeReflection in DielectricMetal.
|
|
|
|
o Run:
|
|
---
|
|
+ Updated date to run-manager.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ OpenGL: G4OpenGLTransform3D.cc: simplified implementation for
|
|
GetMatrix() to allow for porting on future CLHEP series.
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
|
|
+ electromagnetic/MuonProcesses
|
|
o Modified HistoManager and Messenger in order to allow a multirun job.
|
|
+ electromagnetic/PhotonProcesses
|
|
o Modified HistoManager and Messenger in order to allow a multirun job.
|
|
+ electromagnetic/TestEm2
|
|
o Updated acceptance numbers in input macro.
|
|
o Fixed problem in initialisation of RunAction.
|
|
+ electromagnetic/TestEm4
|
|
o Modifications in RunAction for histograms management for JAIDA.
|
|
+ electromagnetic/TestEm6
|
|
o Correctly defined all UI subdirectories.
|
|
o Modifications in RunAction for histograms management for JAIDA.
|
|
+ electromagnetic/TestEm10
|
|
o Removed obsolete processes from PhysicsList.
|
|
+ extended/field
|
|
o Minor cleanup of PhysicsLists.
|
|
+ extended/optical
|
|
o Fixed compilation error and warnings for LXe on Linux/gcc compiler.
|
|
+ novice/N05
|
|
o Added protection for negative proposed step in ExN05MinEkineCuts.
