0002 Geant4 8.0 - patch-01 Release Notes
0003 -----------------------------------
0004
0005 10 February 2006
0006
0007 List of fixes included in this public patch since the public release 8.0:
0008
0009 o Digits & Hits:
0010 -------------
0011 + Added missing methods in G4VDigiCollection and G4TDigiCollection.
0012 Addresses problem report #786.
0013
0014 o Geometry:
0015 --------
0016 + divisions
0017 o Added missing setting of mother-logical pointer in constructors of
0018 G4PVDivision. Fixes problem report #829.
0019 o Added missing checks for illegal constructs of G4PVDivision (NULL
0020 pointer to mother logical and self-placement).
0021 o Fixed check for generic construct in G4ParameterisationPolycone and
0022 G4ParameterisationPolyhedra: allow it for the automatic replicated
0023 instance.
0024 o Cache information about axis of division and provided accessor method
0025 GetDivisionAxis() in G4PVDivision.
0026 + navigation
0027 o Addressing problem with convergence in LocateIntersectionPoint()
0028 of G4PropagatorInField. The problem, identified by Atlas, was
0029 observed when requesting high precision, i.e. small values of
0030 eps_min/max, delta_one_step, due to need for small delta_intersection.
0031 Increased maximum iterations (from 100 to 10000) until correct
0032 information can be return an Exception is thrown in case of too many
0033 iterations; a warning is thrown in case over 1000 iterations.
0034 + solids/BREPS
0035 o Use explicit 'HepGeom' namespace for 'Identity', to allow for
0036 porting on Windows/VC++ when using CLHEP-2.0.X.
0037 + solids/CSG
0038 o G4Sphere: fixed bug in DistanceToOut() for theta intersections.
0039 Fixes problem report #830.
0040 + solids/specific
0041 o Fixed visibility of soft edges for visualization of twisted solids.
0042 o G4TwistedTubs and G4VTwistedFaceted::CreatePolyhedron(): changed
0043 parameterised polyhedron mesh approximation in terms of
0044 G4Polyhedron::GetNumberOfRotationSteps().
0045 o Fixes in G4EllipticalCone:
0046 - Changed GetPointOnSurface(), which was not uniform in endcaps.
0047 - Bug fix in Inside(), which was not correct for the elliptic mantel.
0048 Made test similar as in G4EllipticTube.
0049 - Several fixes in DistanceToIn/Out() resolving problems of looping
0050 events.
0051 + volumes
0052 o G4AssemblyVolume: fixed initialisation of names for placed volumes
0053 which was corrupted after migration to <sstream> as side effect.
0054
0055 o Particles:
0056 ---------
0057 + Bug fix for G4ParticleDefinition, was causing improper behavior of
0058 GetAtomicNumber() method for ions. Fixes problem report #827.
0059
0060 o Electromagnetic processes:
0061 -------------------------
0062 + standard:
0063 o Fix in G4PolarizedComptonScattering, returning PostStepDoIt()
0064 for G4ComptonScattering52. Fixes problem report #478.
0065
0066 o Hadronic Processes:
0067 ------------------
0068 + management:
0069 o G4HadronicProcess: fixed problem report #611. Problems caused when
0070 hadronic interactions reset stopButAlive particle to Alive.
0071 o Added diagnostics when hadronic exceptions occur in G4HadronicProcess
0072 and G4EnergyRangeManager.
0073 + models/binary_cascade:
0074 o Fixed problem report #794. Projectile nucleus needs to be centered.
0075 + models/chiral_inv_phase_space/body:
0076 o Fixed trivial compilation warning.
0077 + models/de_excitation:
0078 o G4NuclearLevelManager: print a warning if no data file is present.
0079 Addressed problem report #814.
0080 o G4ParaFissionModel: fix for compilation error, following problem
0081 report #817.
0082 + models/neutron_hp:
0083 o Fixes core dump observed when neutron energy is close to 20 MeV.
0084 + models/radioactive_decay
0085 o G4NuclearDecayChannel::BetaDecayIt(): check for negative sqrt()
0086 argument in 'daughtermomentum[1]'. Fixes problem report #822.
0087 + stopping:
0088 o Set process type to be 'fHadronic'. Was not set previously.
0089 + util:
0090 o G4ReactionDynamics: added array bounds protection in TwoCluster().
0091
0092 o Processes cuts:
0093 --------------
0094 + Fix in G4VRangeToEnergyConverter::Convert() to recalculate the energy
0095 loss table if new elements are added. Fixes problem report #831.
0096
0097 o Track:
0098 -----
0099 + G4ParticleChangeForRadDecay is now derived from G4ParticleChangeForDecay.
0100
0101 o Transportation:
0102 --------------
0103 + G4Transportation: the particle's charge is now taken from the dynamic
0104 particle, so that it can take into account changes from the interaction
0105 of an ion with matter (eg stripping e-).
0106 + Corrected problem with suspended tracks, addressing problem report #802.
0107 Added StartTracking() method which takes over responsibility to clear
0108 the state for a new track, and to message other relevant component to
0109 clear their state.
0110
0111 o Visualization:
0112 -------------
0113 + management:
0114 o Fixed bug that omits geometry volumes from file-based visualization
0115 drivers for first /run/beamOn.
0116 o Added friend status for ray-tracer.
0117 + RayTracer:
0118 o Fix behavior of messengers when RayTracerX is used.
0119 o Allow for multiple ray tracers.
0120 o Separated out the original ray tracer to be used by viewers.
0121
0122 o Data:
0123 ----
0124 + New data set for high-precision neutron processes G4NDL-3.8
0125 o Added Gadorinium data (source ENDF/B-VI).
0126 o Replaced: Inelastic/CrossSection/17_nat_Chlorine and
0127 Inelastic/F10/28_62_Nickel (source ENDF/B-VI).
0128 o Removed: Inelastic/CrossSection/32_70|72|73|74|76_Germanium
0129
0130 o Examples:
0131 --------
0132 + Updated reference outputs.
0133 + extended/electromagnetic/TestEm7
0134 o Trivial fix of memory leak.
0135 + extended/medical/GammaTherapy
0136 o Substituted PreciseRange with CSDARange.
