0002 Geant4 8.3 - patch-01 Release Notes
0003 -----------------------------------
0004
0005 17 August 2007
0006
0007 List of fixes included in this public patch since the public release 8.3:
0008
0009 o Configuration:
0010 -------------
0011 + liblist.c: fixed problem affecting recent CygWin installations on
0012 Windows in parsing the buffer for the generation of libname.map.
0013 + binmake.gmk: defined OUT internal variable specifying the proper
0014 compilation/linking option to Unix or Windows compilers: '-o '
0015 and '/Fe' respectively. Cleared <TAB> characters where not necessary.
0016 + SUN-CC.gmk: forced -xO2 as optimisation level.
0017
0018 o Geometry:
0019 --------
0020 + magneticfield:
0021 o Relaxed 'FatalException' to 'Warning' in method
0022 G4MagIntegratorDriver::AccurateAdvance() for case of step zero and
0023 return previous value. This fixes problem observed by ATLAS and CMS
0024 in release 8.3 when using very conservative values for field
0025 parameters.
0026 + solids/specific:
0027 o Fixes in G4Polyhedra::GetPointOnSurface():
0028 Correctly treat 'totalPhi' instead of 'endPhi' for the case of open
0029 shapes and 'twopi' for not open shapes.
0030 Introduced fix for the case when number of sectors (numSide) is equal
0031 to 1. At the origin of problems observed when checking overlaps for
0032 polyhedra solids defined as such.
0033
0034 o Global:
0035 ------
0036 + Changed date for patch-01 to release 8.3.
0037
0038 o Materials:
0039 ---------
0040 + G4NistElementBuilder: added protection (Z>=limitNumElements) inside
0041 method BuildElement().
0042
0043 o Hadronic Processes:
0044 ------------------
0045 + models/chiral_inv_phase_space:
0046 o G4QuasiFreeRatios: fixed DB filling (ID update), responsible for
0047 excessive growth of memory in long runs. Corrected indexing and
0048 computation of cos(theta).
0049 + util:
0050 o Three bug fixes in G4ReactionDynamics::TwoCluster(): removed a sharp
0051 peak at 180 degrees by fixing a units error and fixed an error in
0052 sampling the momentum transfer. Fixed array bound violation which
0053 caused in some rare occasions an infinite loop.
0054
0055 o Physics Lists:
0056 -------------
0057 + Correct use of QElasticPhysics in QGSP_QEL list.
0058
0059 ----------------------------------------------------------------------------
0060
0061 Technical Notes
0062 ---------------
0063
0064 o This patch should be applied on top of release 8.3
0065 o Technical notes distributed for release 8.3 are also applicable and
0066 valid for this patch.
