0006
0007 List of fixes included in this public patch since the public release 9.1:
0008
0009 o Configuration:
0010 -------------
0011 + Added commented lines for OpenGL setup in Darwin-g++.gmk for MacOS
0012 10.5 Leopard, pending fix from Apple.
0013
0014 o Geometry:
0015 --------
0016 + magneticfield:

0018 variable already defined in G4MagIntegratorStepper.

0020 + navigation:
0021 o G4PropagatorInField: changed condition for 'ReEstimationEndPoint'
0022 in order to better handle very strict parameters of propagation.
0023 Also added more verbosity in case of error for negative step.
0024 Fixes rare problem observed in production by ATLAS. (*)
0025 o G4PhantomParameterisation: bug fix in GetReplicaNo() to catch
0026 overflows in X and Y.

0028 + solids/BREPS: (*)
0029 o Fixed bug in G4BREPSolidPolyhedra::DistanceToOut() for cases of
0030 particle passing the border of two touching surfaces.
0031 o G4BREPSolidBox: fixed problem in the constructor in definition of
0032 the side for the normal to surface.
0033 + solids/specific:
0034 o In G4ExtrudedSolid::MakeFacets(), now adding triangular facets before
0035 quadrangular ones, following logic behind G4TessellatedSolid.
0036 Fixes occasional crashes when defining solids with mixed facets.
0037 Corrected triangularization of polygon, now correctly handling case
0038 of concave shapes.
0039 o Corrected order of arguments in G4Paraboloid constructor.
0040 + volumes:
0041 o Fixed problem of double-deletion of rotation matrix in destructor
0042 of G4AssemblyVolume.
0043
0044 o Global:
0045 ------
0046 + Changed date for patch-01 to release 9.1.
0047
0048 o Graphics Representations:
0049 ------------------------
0050 + HepPolyhedron: fixed bug and improvement in the visualization of
0051 G4Paraboloid.
0052
0053 o Interfaces:
0054 ----------
0055 + G4UItcsh: fixed problem with <Ctl-D> termination for bash users.
0056 + G4UIQt: some improvements for Qt3, corrections of some bugs.
0057 + G4UIQt_moc: added versions for QT_MOC_REVISION 28,58 and 59.
0058
0059 o Electromagnetic Processes:
0060 -------------------------
0061 + Standard:
0062 o G4PAIModel, G4PAIPhotonModel: added extra protection to guarantee
0063 correct usage of the last bin for the table of energy transfers.
0064 Fixes problem report #995.
0065 o G4hIonisation, G4ionIonisation, G4ionGasIonisation: fixed
0066 computation of non-ionizing energy loss: at the last ionization step
0067 and at energies above 2 MeV for protons.
0068 o G4eCoulombScatteringModel: using safer numerical espression.
0069 + Utils:
0070 o G4EmCorrections: improved CPU by usage of expansions and precalculated
0071 values of Z^0.23.
0072 o G4VEnergyLossProcess: fixed list of "collaborative" processes needed
0073 for sub-cutoff option.
0074
0075 o Hadronic Processes:
0076 ------------------
0077 + cross_sections:
0078 o G4PhotoNuclearCrossSection and G4ElectroNuclearCrossSection: fixed
0079 wrong return value (was zero instead of pseudo-inf) and commented out
0080 extra debug warning. Moved unnecessary inline methods to implementation.
0081 + models/chiral_inv_phase_space:
0082 o Fixed problem of non-reproducibility induced by
0083 G4QElasticCrossSection. (*)
0084 o Reduce memory allocation induced by use std::deque collection in (*)
0085 G4QHadron class; temporary workaround by replacing it with std::list.
0086 o G4ChiralInvariantPhaseSpace: moved some unnecessary inline methods to
0087 implementation and fixed non-reproducibility due to difference in
0088 initialisation.
0089 o G4StringChipsInterface: fixed non-reproducibility due to difference in
0090 initialisation. (*)
0091 o Commented out debug printout in G4Quasmon.
0092 o Fixed compilation warning on SUN/CC compiler in G4QNucleus.
0093 + models/coherent_elastic:
0094 o G4DiffuseElastic: removed dependency on other elastic models.
0095 o G4ElasticHadrNucleusHE: fixed non-reproducibility problem.
0096 Removed commented part of old code and added more formatting.
0097 o G4HadronElastic: restored threshold to G4ElasticHadrNucleusHE
0098 model at 1 GeV.
0099
0100 o Persistency:
0101 -----------
0102 + gdml:
0103 o Fixed vertex referencing for tessellated-solid in G4GDMLSolids.
0104 o Fixed entity resolution in G4GDMLBase.
0105 o Fixed naming of convention for external files in G4GDMLStructure.
0106
0107 o Physics Lists:
0108 + G4EmExtraPhysics: fixed swapping of synchrotron radiation and mu-nuclear
0109 activation. Addressing problem report #993.
0110
0111 o Track:
0112 -----
0113 + Added non-ionizing energy loss to EM physics (classes
0114 G4ParticleChangeForGamma and G4ParticleChangeForLoss).
0115
0116 o Transportation:
0117 --------------
0118 + G4Transportation & G4CoupledTransportation: allow for clearing the
0119 state of all chord-finders using G4FieldManagerStore. Assures for
0120 event reproducibility in case multiple local fields are used.
0121 + Syncronised files with CVS HEAD.
0122
0123 o Examples:
0124 --------
0125 + extended/electromagnetic/TestEm7:
0126 o Added PhysListStandardNR PhysList in which G4ScreenedNuclearRecoil
0127 process is used ("standardNR");
0128 o Added computation of mean NIEL energy loss.
0129 o Fixed experimental physics lists if single scattering models are used
0130 instead of multiple scattering. Set nuclear stopping flag for ionisation
0131 to "false".
0132 + extended/gdml:
0133 o Added entity.gdml and materials.xml to demonstrate the ability of
0134 the parser of resolving entities.
0135 o Fixed axes.gdml and diamond.gdml according to tessellated-solid
0136 specifications.
0137 + extended/medical/DICOM:
0138 o Fix to not use 'rindex' in DicomHandler class to avoid problems
0139 on Windows.
0140
0141 (*) Fixes also included in the patched releases 9.0.p02 and 8.3.p02.
