Geant4 10.4 - patch-02 Release Notes | ||
------------------------------------ | ||
|
||
25 May 2018 | ||
|
||
List of fixes included in this public patch since the public release 10.4.p01: | ||
|
||
o Configuration: | ||
------------- | ||
+ CMake: | ||
o Updated to data-set G4RealSurface-2.1.1. | ||
Addressing problem report #2043. | ||
+ GNUMake: | ||
o architecture.gmk: corrected default path for external expat and zlib. | ||
o Darwing-clang.gmk: removed -pthread and -fPIC compilation options. | ||
o WIN32-VC.gmk: updated obsolete configuration for Qt5. | ||
|
||
o Event: | ||
----- | ||
o Use G4TrackStack as default and make use of G4SmartTrackStack optional. | ||
Addressing problem report #2040. | ||
|
||
o Externals: | ||
--------- | ||
+ Corrected GNUmakefile on Windows. | ||
|
||
o Geometry: | ||
-------- | ||
+ navigation: | ||
o G4PathFinder: in DoNextLinearStep(), use flag for relocated point to | ||
signal move from call to ReLocate(), and ensure that new point is used | ||
in cross-checks in subsequent Locate(). | ||
Fix to revert change previously introduced in release 10.4, to keep | ||
fMinStep as 'logical' value, which can be kInfinity when step is not | ||
limited by Navigators. Resolves warnings issued by G4PathFinder for | ||
inaccuracies in relocation. Addressing problem report #2033. | ||
o G4Navigator::GetLocalExitNormal(): fix for normal calculated at the | ||
endpoint of current step, on a 'candidate' next volume. Adds missing | ||
transformation to the frame of the current volume. | ||
Addresses problem report #2054. | ||
o G4Navigator: fix in Set/RestoreSavedState() for setting of | ||
ReplicaNumber. | ||
o G4SafetyHelper: do not limit memorisation of safety in case of parallel | ||
geometries (when a length is not passed to safety method). | ||
Fix to include full message in Exception. | ||
+ solids/Boolean: | ||
o G4BooleanSolid: enhanced warning message for the case of an invalid | ||
(NULL) Boolean construct in GetPointOnSurface() and StackPolyhedron(). | ||
Use -1 instead of 0 as default initialisation value for area and | ||
capacity, so to distinguish cases when values are zero referring to | ||
NULL Boolean constructs. | ||
o G4UnionSolid: define simple bounding-box and make use of early returns | ||
in Inside() for points laying outside. | ||
o Improved contruction of G4DiplacedSolid to combine transformations for | ||
nested displaced types. | ||
o Replaced USOLIDS_LIBRARIES with VECGEOM_LIBRARIES in sources.cmake. | ||
+ solids/CSG: | ||
o G4Box: simplified and optimised calculation of normal in method | ||
DistanceToOut(p,v,..). | ||
o Replaced USOLIDS_LIBRARIES with VECGEOM_LIBRARIES in sources.cmake. | ||
+ solids/specific: | ||
o Corrected conversion of input parameters to internal structure (used | ||
for caching for adoption in GDML persistency) in G4UPolycone and | ||
G4UPolyhedra wrappers. | ||
o Replaced USOLIDS_LIBRARIES with VECGEOM_LIBRARIES in sources.cmake. | ||
|
||
o Global: | ||
------ | ||
+ Updated date and version for 10.4.p02. | ||
|
||
o Interfaces: | ||
---------- | ||
+ G4UIQt: fixed bug with command guidance including HTML tags inside | ||
(<, > and &) and for "critical errors" message. | ||
|
||
o Particles: | ||
--------- | ||
+ G4PhaseSpaceDecayChannel: fixed incorrect indexing in ManyBodyDecayIt(), | ||
causing incorrect setting of daughter momentum in 4-body phase-space | ||
decay. Addressing problem report #2053. | ||
|
||
o Persistency - gdml | ||
------------------ | ||
+ Protect printout of progress in reading/writing by G4VERBOSE. | ||
|
||
o Physics Lists | ||
------------- | ||
+ constructors/electromagnetic: | ||
o G4EmModelActivator: fix for Opt4 and single-scattering activation. | ||
Addressing problem report #2045. | ||
|
||
o Processes - Electromagnetic: | ||
--------------------------- | ||
+ lowenergy: | ||
o G4LivermorePhotoElectricModel: fixed incorrect deletion of static | ||
members when models defined per region. Addressing problem report #2052. | ||
|
||
o Processes - Hadronic: | ||
-------------------- | ||
+ models/particle_hp: | ||
o G4ParticleHPFissionFS: protect against very rare cases of division | ||
by zero. | ||
+ models/radioactive_decay: | ||
o G4RadioactiveDecay: in ConvolveSourceTimeProfile(), switch from | ||
std::exp() to std::expm1() where small exp arguments are expected. | ||
This greatly reduces cancellation errors as well as the accumulated | ||
error in the variance reduction weight calculation. Although negative | ||
weights still occur, their size is reduced by about ten orders of | ||
magnitude, enough to set negative weights to zero. | ||
G4Radioactivation::ConvolveSourceTimeProfile(): same as above. | ||
Addresses problem report #1480. | ||
o Make sure last stable nuclide in decay chain is included as secondary | ||
in G4RadioactiveDecay::AddDeexcitationSpectrumForBiasMode() and in | ||
G4Radioactivation::AddDeexcitationSpectrumForBiasMode(). | ||
Addresses problem report #2024. | ||
|
||
o Run: | ||
--- | ||
+ G4ExceptionHandler: added track/step/volume information when an | ||
exception happens while event is being processed. | ||
|
||
o Visualization: | ||
------------- | ||
+ modeling: | ||
o Fixed bug in calculation of mass of parallel world, protecting for | ||
the case of no material assigned. Addressing problem report #2039. | ||
+ Tree: | ||
o Fixed bug in suppressed writing of repeated parameterised volumes. | ||
o Improved command guidance and advice printing. | ||
|
||
o Data sets: | ||
--------- | ||
+ Patched data set for measured optical surface reflectance | ||
G4RealSurface-2.1.1: | ||
o Merged LBNL LUTs data introduced in 2.0 with the Davis LUTs. | ||
Addressing problem report #2043. | ||
|
||
o Examples: | ||
-------- | ||
+ extended/optical/LXe: | ||
o Fixed header guard. Addressing problem report #2041. | ||
|
||

||
