Geant4 9.0 - patch-02 Release Notes
|
|
-----------------------------------
|
|
|
|
25 January 2008
|
|
|
|
List of fixes included in this public patch since the public release 9.0.p01:
|
|
|
|
o Error Propagation:
|
|
-----------------
|
|
+ G4ErrorFreeTrajState: corrected bug in one of the transformation
|
|
matrix terms. Addresses problem report #971.
|
|
+ G4ErrorFreeTrajParam: corrected normalization of Y and Z coordinates.
|
|
+ G4ErrorPropagator: removed call to exit() and some cleanup.
|
|
|
|
o Event: (*)
|
|
-----
|
|
+ G4ParticleGun:
|
|
o Added class member 'particle_momentum' and method
|
|
SetParticleMomentum().
|
|
o Added private copy constructor and =, ==, += operators to
|
|
Addressing problem report #984.
|
|
+ Modified G4SPSEneDistribution to adress problem report #988.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ management: (*)
|
|
o Fixed typo in forcing minimum number of points in method
|
|
G4VSolid::EstimateSurfaceArea(). Addresses problem report #981.
|
|
+ navigation: (*)
|
|
o G4PropagatorInField:
|
|
- Fixes for compilation of code under G4DEBUG_FIELD
|
|
(problem report #982).
|
|
- Changed condition for 'ReEstimationEndPoint' in order to better
|
|
handle very strict parameters of propagation. Also added more
|
|
verbosity in case of error for negative step.
|
|
Fixes rare problem observed in production by ATLAS.
|
|
- Added extra check of method LocateIntersectionPoint() arguments.
|
|
+ solids/Boolean: (*)
|
|
o Boosted performance for response of Inside() for G4SubtractionSolid
|
|
and G4UnionSolid according to suggestion in problem report #979.
|
|
+ solids/BREPS: (*)
|
|
o Fixed bug in G4BREPSolidPolyhedra::DistanceToOut() for cases of
|
|
particle passing the border of two touching surfaces.
|
|
o G4BREPSolidBox: fixed problem in the constructor in definition of
|
|
the side for the normal to surface.
|
|
+ solids/CSG: (*)
|
|
o G4Torus:
|
|
- Fixed bug in CalculateExtent() for case of non-rotated full-Phi
|
|
torus definition: added protection against negative value for sqrt()
|
|
and corrected formula for 'delta'.
|
|
Fixes problem of NaN detected in initialisation by CMS.
|
|
- Fixed bug in SolveNumericJT(): corrected handling of complex roots.
|
|
Addresses problem report #969.
|
|
o Fixed problem of undefined side for valid surface normal in case of
|
|
'Phi' section and direction through the center of either a G4Tubs or
|
|
G4Cons shape.
|
|
+ solids/specific: (*)
|
|
o Removed debug printout in G4Polycone::GetPointOnCone().
|
|
|
|
o Global:
|
|
------
|
|
+ Changed date for patch-02 to release 9.0.
|
|
|
|
o Management Processes:
|
|
--------------------
|
|
+ G4WrapperProcess: fixed double definition of method PreparePhysicsTable()
|
|
in the header and moved inline implementations of virtual methods to
|
|
source file.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ management: (*)
|
|
o G4HadronicProcess::FillTotalResult(): fix addressing problem report
|
|
#967, replaced call to 'aT.GetGlobalTime()' with an internal variable.
|
|
+ models/cascade:
|
|
o Fixed angular distribution for nucleon-nucleon elastic scattering
|
|
above 2.8 GeV.
|
|
+ models/chiral_inv_phase_space: (*)
|
|
o Fixed problem of non-reproducibility induced by G4QElasticCrossSection
|
|
and G4StringChipsInterface.
|
|
o Reduced memory allocation induced by use std::deque collection in
|
|
G4QHadron class; temporary workaround by replacing it with std::list.
|
|
+ models/high_energy: (*)
|
|
o G4HEInelastic::TuningOfHighEnergyCascading(): fixed incorrect
|
|
assignment of leading particle to low energy backward nucleons and
|
|
fragments. This bug caused high energy backward particles to be
|
|
emitted from high energy collisions.
|
|
o G4HEPionMinusInelastic: fixed incorrect 'Imax' in sampling of charge
|
|
exchange.
|
|
+ stopping: (*)
|
|
o G4StopElementSelector: fixed typo in Primakoff formula for
|
|
capture velocity.
|
|
o G4MuonMinusCaptureAtRest: fixed old memory leak.
|
|
o Removed old-style copyright from all headers and fixed Software
|
|
Reference Manual tags.
|
|
|
|
o Examples:
|
|
--------
|
|
+ advanced/underground_physics:
|
|
o Corrected micrometer unit in macros from mum to um (old bug since 8.2).
|
|
|
|
|
|
(*) Fixes also included in the patched release 8.3.p02.
