Geant4 10.1 - patch-03 Release Notes
|
|
------------------------------------
|
|
|
|
5 February 2016
|
|
|
|
List of fixes included in this public patch since the public release 10.1.p02:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ CMake:
|
|
o Updated Apple Clang detection to work on Xcode-7.
|
|
o Always use libc++ with Apple Clang so that std-supporting library is
|
|
used for C++11 mode on older Mac systems where libstdc++ is the default.
|
|
o Updated std-flag setting rules.
|
|
+ GNUMake:
|
|
o Updated X11 settings in MacOS platform.
|
|
o Added settings for C++ standards in platform specific scripts.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ Fixed G4Analysis::Tokenize() which was failing when processsing a string
|
|
containing opening double quota without a closing one.
|
|
+ Fixed handling ntuples created in MT mode on master thread
|
|
This fixes the problem reported in hypernews (#459) and the problem
|
|
of deleting non-empty Root file containing only ntuples.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ divisions:
|
|
o Fix for use of rotation matrix in G4VDivisionParameterisation in
|
|
MT-mode; use thread-local pointer for rotation matrix as member of the
|
|
class G4VDivisionParameterisation and set it to suto-delete.
|
|
Removed unnecessary thread-local verbose flag.
|
|
Addressing problem reports #1743 and #1758.
|
|
o Set as unsupported divisions of polycone and polyhedra in MT-mode.
|
|
+ magneticfield:
|
|
o Added check in G4ChordFinder against number of iterations in
|
|
FindNextChord(), to identify potential cases of lack of convergence.
|
|
o Better diagnostics text in case of errors in G4FieldTrack and
|
|
G4UniformMagField.
|
|
o Added explanation comment in G4MagHelicalSteper.
|
|
+ navigation:
|
|
o G4MultiLevelLocator::EstimateIntersectionPoint(): fix for logic error
|
|
in keeping consistent candidate intersection. Copes with case that a
|
|
candidate intersection is not found in the next segment (typically in
|
|
the 'second half' part).
|
|
Ensure that splitting of step (new level/depth) advances the required
|
|
length, used when adding a new level/depth.
|
|
Revised condition of 'while' loop which ensures that a new candidate
|
|
intersection exists. Corrected the resetting of 'first_section' flag.
|
|
Replaced fatal error for exceeding max steps with warning and signal
|
|
'looping' for too many steps; G4PropagatorInField detects this
|
|
condition, and identifies it as a 'Looping Particle' which is then
|
|
flagged; the calling class (Transportation, PathFinder) is expected
|
|
to stop the tracking of this particle after a few of these steps.
|
|
Addressing issue seen by ALICE (non-finishing of step due to poor
|
|
advances).
|
|
o G4VIntersectionLocator: added new logging methods & revised interfaces.
|
|
o G4NavigationLogger: added method to report issue with normal that
|
|
is the result of applying a rotation.
|
|
o G4NormalNavigation, G4VoxelNavigation: added check of rotated exit
|
|
normal.
|
|
o Relaxed condition for zero or almost-zero steps in G4ReplicaNavigation
|
|
and G4Navigator, to allow for faster progression in case of stuck tracks
|
|
in 3D scoring meshes. Addressing old problem report #1432.
|
|
o Fix in G4ReplicaNavigation::ComputeStep() for correct setting of copyNo
|
|
for particle entering. Fixes issue of negative copyNo observed in nested
|
|
replica setups. Addressing problem report #1634.
|
|
o Moved check for overlaps in G4Navigator::ComputeStep() within G4VERBOSE.
|
|
Addressing problem report #1811.
|
|
+ solids/Boolean:
|
|
o Checked for potential never-ending loops. Replaced while-do loop with
|
|
bounded for-loop in G4IntersectionSolid::DistanceToIn(p,v).
|
|
Also addressing problem report #1821.
|
|
+ solids/CSG:
|
|
o Introduced check in G4Sphere::DistanceToIn(p,v) for concave Theta and
|
|
point located on the origin. Also make proper use of radial tolerance in
|
|
DistanceToOut(p,v).
|
|
o Fixed Coverity defect in G4CutTubs::GetMaxMinZ().
|
|
+ solids/specific:
|
|
o Added specialised implementation for GetCubicVolume() in
|
|
G4TessellatedSolid. Added debug printouts withing G4SPECSDEBUG for
|
|
DistanceToIn/Out(p,v) to identify potential wrong responses.
|
|
o Removed redundant condition in G4Polyhedra and G4polycone
|
|
SetOriginalParameters() method.
|
|
o Minor code cleanup in G4SurfaceVoxelizer.
|
|
o Checked for potential never-ending loops.
|
|
+ volumes:
|
|
o Enabled paramerisation by solid type in G4GeometryWorkspace in MT-mode.
|
|
Assumes solids being parameterised are declared thread-local in the
|
|
user's parameterisation class and allocated just once.
|
|
|
|
o Global:
|
|
------
|
|
+ Tune radial tolerance to same value as for Cartesian tolerance in
|
|
G4GeometryTolerance.
|
|
+ Corrected conditions for proper treatment of gcc-5 in tls.hh and
|
|
G4Threading.hh.
|
|
+ Removed unused and buggy operator=(const G4String&) in G4SubString.
|
|
Added string length check in G4String::operator==().
|
|
Added missing 'inline' specification to functions in G4String.
|
|
+ Force use of G4MT wrappers for Intel-icc compiler for random numbers.
|
|
+ Updated date and version for 10.1.p03.
