Geant4 10.1 - patch-02 Release Notes
|
|
------------------------------------
|
|
|
|
19 June 2015
|
|
|
|
List of fixes included in this public patch since the public release 10.1.p01:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ CMake:
|
|
o Added extensions to allow use of system CLHEP granular libraries.
|
|
Provide new advanced option GEANT4_USE_SYSTEM_CLHEP_GRANULAR, which can
|
|
be set to enable use of CLHEP granular libraries from the system; when
|
|
activated, use new FindCLHEP interface to search for Geant4's required
|
|
Export and document a new variable "Geant4_system_clhep_ISGRANULAR" that
|
|
clients can query to check whether the system CLHEP was linked in granular
|
|
mode. Support CLHEP granular library listing in '--libs' argument.
|
|
Added CLHEP_ROOT_DIR to CMake cache, allowing it to be edited in the
|
|
CMake curses/GUI.
|
|
o Updated AppleClang version regex to properly parse LLVM version
|
|
number in Xcode 6.3.
|
|
o Corrected Qt5 settings for test applications.
|
|
o Added '-no-gcc' compilation option for Intel-icc compiler.
|
|
+ GNUMake:
|
|
o Updated CPPFLAGS for Linux-icc and WIN32-g++ configurations.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ Updated to g4tools 1.17.2: changes for Windows (MinGW) to use '_MSC_VER'
|
|
in place of 'WIN32' flag. Addressing problem report #1721.
|
|
|
|
o Event:
|
|
-----
|
|
+ Increased level of verbosity of /gps/verbose command.
|
|
/gps/verbose now acts globally on all sources in case of multiple ones
|
|
(no need to activate verbosity for each source).
|
|
Protecting the command /gps/source/set in case of out-of-bound index.
|
|
Addressing problem report #1744.
|
|
+ Clean up code and removed not needed thread-local data that
|
|
need to be shared for UI commands to work properly.
|
|
+ Fixes for Coverity defects.
|
|
|
|
o Externals:
|
|
---------
|
|
+ CLHEP:
|
|
o Fixed usage of std::abs() in RandGaussZiggurat.
|
|
o Moved static methods handling static data in G4RandGauss from inline
|
|
to source. Addressing problem report #1754.
|
|
o Switch off warnings for deprecated calls to auto_ptr in Utility headers.
|
|
+ USolids:
|
|
o Corrected string returned as type-ID by GetEntityType() to conform
|
|
to shape kind in: UExtrudedSolid, UMultiUnion, UQuadrangularFacet,
|
|
UTessellatedSolid, UTrap, UTriangularFacet and UVCSGfaceted.
|
|
o Replaced Exception IDs in UUtils to avoid clashes with wild global
|
|
extern functions in Root.
|
|
o UVector3: made data private and defined accessors x(), y() and z().
|
|
Made implementations operators +(), -(), *(), and /() inline.
|
|
Adapted all classes to the change.
|
|
o Fixed DistanceToOut(p) and Inside(p) in USphere for sphere cut in theta
|
|
for point (0,0,0) and for cases when Start/End angle have not to be taken
|
|
in account (STheta==0 || eTheta==pi).
|
|
o Added method GetPointOnEdge() to UBox.
|
|
o Fixed Coverity defect for unused variable quantity in UCons.
|
|
o Some code cleanup and minor fixes...
|
|
|
|
o Geometry:
|
|
--------
|
|
+ divisions:
|
|
o G4VDivisionParameterisation: avoid creation/deletion of rotation matrix
|
|
for ChangeRotMatrix(). Addressing problem report #1743.
|
|
o Fixed Coverity defect in G4ReplicatedSlice for uninitialised pointer.
|
|
+ management:
|
|
o Added streaming operator <<() to G4AffineTransform.
|
|
o Removed unused data-member in G4LogicalVolume, and fixed minor
|
|
Coverity defect for unitialised member 'fBiasWeight' in constructor.
|
|
o G4USolid: use accessors x(), y() and z() from UVector3, instead of
|
|
directly accessing its data-members.
|
|
Use scoped enum for EnumSide if c++11 enabled.
|
|
+ navigation:
|
|
o Enabled ComputeStep() in navigation helper classes (Normal, Voxel,
|
|
and Parameterised) to recognise invalid points outside the mother
|
|
volume. Before it was not recognised, but used instead as a numeric
|
|
value (kInfinity). In case it was kInfinity, this meant the volume
|
|
could not be chosen, and the track never exited the volume. This
|
|
invalid response now triggers an immediate exit from the volume
|
|
and daughters do not need to be considered.
|
|
Use return value of motherSolid DistanceToOut(p,v), each time
|
|
that it is called. Correct 'invalid' answer ('kInfinity' or
|
|
negative) to zero.
|
|
o Improvements in G4PropagatorInField to enable identification of first
|
|
and last step in a volume, when tracking in a field.
|
|
Addressing old problem report #1032.
|
|
Added new methods to report looping and stuck tracks and correction
|
|
for roundoff issue.
|
|
o NavigationLogger: added method for Reporting a point is outside the
|
|
mother volume: CheckAndReportBadNormal(), CheckDaughterEntryPoint().
|
|
o G4AuxiliaryNavigationServices: optimised to reuse dot product, rather
|
|
than recomputing; added optional printout (protected by debug flag).
|
|
o G4VIntersectionLocator: added PrintStatus() method with additional
|
|
ostringstream argument.
|
|
o Code cleanup and various minor fixes.
|
|
+ solids/Boolean:
|
|
o G4UMultiUnion: use accessors x(), y() and z() from UVector3, instead
|
|
of directly accessing its data-members.
|
|
+ solids/CSG:
|
|
o Fixed calculation of Normal in G4Para for kPX and kMX sides in
|
|
DistanceToOut(p,v) and ApproxSurfaceNormal(p).
|
|
Addressing problem report #1736.
|
|
o Fixed DistanceToOut(p) and Inside(p) in G4Sphere for sphere cut in theta
|
|
for point (0,0,0) and for cases when Start/End angle have not to be taken
|
|
in account (STheta==0 || eTheta==pi).
|
|
Added corresponding test cases to unit test for testG4Sphere.
|
|
Fix triggered by analysing setup provided in problem report #1702.
|
|
o Use accessors x(), y() and z() from UVector3 in USolids wrappers, instead
|
|
of directly accessing its data-members.
|
|
o Fixed Coverity defect for unused variable quantity in G4Cons.
|
|
+ solids/specific:
|
|
o Use accessors x(), y() and z() from UVector3 in USolids wrappers, instead
|
|
of directly accessing its data-members.
|
|
+ volumes:
|
|
o Simplified implementation in G4NavigationHistoryPool to make use of simple
|
|
stack of free entries. Pre-allocate size of vectors and inlined GetLevels().
|
|
Also addressing problem report #1730.
|
|
|
|
o Generic Processes:
|
|
-----------------
|
|
+ Transportation:
|
|
o G4Transportation, G4CoupledTransportation: added ability to identify last
|
|
step in volume for the case of propagation in field.
|
|
Addresses old problem report #1032.
|
|
|
|
o Global:
|
|
------
|
|
+ Fix in G4StatDouble to return RMS 0 instead of -1 in the case the number
|
|
of entries is below 2 (fixes arithmetic exceptions in examples for run
|
|
with 1 event only).
|
|
+ Fixed bug in G4CacheReference::Destroy(); modified behavior to identify
|
|
internal inconsistencies and throw exception.
|
|

|
|
Addressing problem report #1739.
|
|

instead, in order to avoid loss of precision due to unit's conversion.
|
|
o Correction for optional stripping of world-volume.
|
|
o Corrected parsing of shape type-ID for MultiUnion in G4GDMLWriteSolids.
|
|
