Geant4 9.0 - patch-01 Release Notes
|
|
-----------------------------------
|
|
|
|
28 August 2007
|
|
|
|
List of fixes included in this public patch since the public release 9.0:
|
|
|
|
o Configuration: (*)
|
|
-------------
|
|
+ liblist.c: fixed problem affecting recent CygWin installations on
|
|
Windows in parsing the buffer for the generation of libname.map.
|
|
+ binmake.gmk: defined OUT internal variable specifying the proper
|
|
compilation/linking option to Unix or Windows compilers: '-o '
|
|
and '/Fe' respectively. Cleared <TAB> characters where not necessary.
|
|
+ SUN-CC.gmk: forced -xO2 as optimisation level.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ magneticfield:
|
|
o Fix to DistChord() method for Helical Steppers: adopt 'special' case
|
|
also for Ang<2pi not only for Ang<pi; use cos() in place of tan(), to
|
|
improve CPU performance.
|
|
o In G4HelixMixedStepper added possibility to call different steppers
|
|
for small steps and add some statistics how offen different steppers
|
|
are called. Improved AdvanceHelix() to be able to make half step and
|
|
full step in one call.
|
|
o G4RKG3_Stepper: improved internal algorithm to use pre-computed values;
|
|
the stepper now gives comparable CPU performance as ClassicalRK4.
|
|
o Changed FatalException to EventMustBeAborted in AccurateAdvance()
|
|
if proposed integration step is negative. (*)
|
|
+ management:
|
|
o Added dummy constructor and destructor to G4VPVParameterisation.
|
|
+ solids/BREPS:
|
|
o Added missing initialisations of kCarTolerance in alternative
|
|
constructors for G4BoundingBox3D, G4Curve, G4CurveRayIntersection,
|
|
G4KnotVector. Addressing problem report #959.
|
|
+ solids/CSG:
|
|
o G4Tubs: fixed bug in DistanceToOut(p,v,..) for negative value under
|
|
sqrt() for the case of point p on the surface and v tangent to the
|
|
surface. Responsible for rare cases of NaN.
|
|
+ solids/specific:
|
|
o Fixes in G4Polyhedra::GetPointOnSurface(): (*)
|
|
Correctly treat 'totalPhi' instead of 'endPhi' for the case of open
|
|
shapes and 'twopi' for not open shapes.
|
|
Introduced fix for the case when number of sectors (numSide) is equal
|
|
to 1. At the origin of problems observed when checking overlaps for
|
|
polyhedra solids defined as such.
|
|
o Fixed dummy constructors of G4Polycone and G4PolyPhiFace for
|
|
initialisation of 'edges' and 'corners'. Added workaround to
|
|
initialisation of 'corners' vector in G4PolyconeSide class, to allow
|
|
for object persistency with Root-I/O.
|
|
o G4EllipticalCone:
|
|
- DistanceToIn(p): corrected answer for p.z()<-zTopCut and for the
|
|
point p on the surface.
|
|
- DistanceToOut(p,v): now returning positive solution or zero when
|
|
crossing the elliptical surface.
|
|
- Fix in DistanceToOut(p) which was giving always zero.
|
|
- Added some formulas on how to pre-calculate 'SemiAxis' and 'zheight'.
|
|
|
|
o Global:
|
|
------
|
|
+ Changed date for patch-01 to release 9.0.
|
|
|
|
o Graphics Representations:
|
|
------------------------
|
|
+ Corrected graphical description for G4EllipticalCone in HepPolyhedron
|
|
and G4Polyhedron.
|
|
+ G4VGraphicsScene: Added default constructor and virtual destructor.
|
|
|
|
o Intercoms:
|
|
---------
|
|
+ G4UIbatch:
|
|
o Bug fixed for the treatment of the last line.
|
|
o Added support for continued line by '\', '_'.
|
|
o String after '#' is treated as comment.
|
|
o White spaces at the head of a line are allowed.
|
|
o Fixed problem on 32bit-Linux.
|
|
+ G4UImanager: fixed bug concerning invalid returned object.
|
|
+ Introduced "/control/getEnv" and "/control/echo" commands.
|
|
|
|
o Electromagnetic Processes:
|
|
-------------------------
|
|
+ Polarisation:
|
|
o Removed/renamed obsolete methods and local variables in
|
|
classes G4VPolarizedCrossSection, G4eplusPolarizedAnnihilation,
|
|
and G4PolarizedAnnihilationModel to clear "shadow" warnings on SUN-CC.
|
|
+ Standard:
|
|
o G4UniversalFluctuation: added protection such that no sampling of
|
|
fluctuations is done if mean energy loss at the step is below minimal
|
|
excitation energy of the media. The fix is important for cases of
|
|
low-dense gases and very small steps.
|
|
+ Utils:
|
|
o G4VEmModel: fixed SelectRandomAtom() method for the selection of
|
|
elements in a compound material.
|
|
+ Xrays:
|
|
o G4VXTRenergyLoss: fixed Valgrind run-time errors for wrong memory
|
|
allocation by removing internal initialisation of Sandia table and
|
|
using Sandia table from materials.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ models/chiral_inv_phase_space: (*)
|
|
o G4QuasiFreeRatios: fixed DB filling (ID update), responsible for
|
|
excessive growth of memory in long runs. Corrected indexing and
|
|
computation of cos(theta).
|
|
+ models/neutron_hp:
|
|
o G4NeutronHPThermalScattering: removed duplicate declaration of
|
|
'dirName', already a class member, to clear compilation warning.
|
|
+ models/util:
|
|
o G4KineticTrack: changed local variable names to clear compilation
|
|
warnings on SUN-CC about hiding.
|
|
+ stopping:
|
|
o Fixed signature of G4MuMinusCaptureCascade::DoCascade() expecting
|
|
'const' as arguments for A and Z. Resolves linking problems on SUN-CC.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ Removed redundant method declarations and minor tidies.
|
|
|
|
o Environments:
|
|
------------
|
|
+ Minor bug fixes to G4Py module; updated geometry wrappers and TestEm0
|
|
example.
|
|
|
|
o Examples:
|
|
--------
|
|
+ advanced/medical_linac:
|
|
o Fixed problem report #880 in DetectorConstruction class.
|
|
o Updated macros; reviewed seed initialisation and modified to use
|
|
default multiple-scattering class instead of MultipleScattering52.
|
|
+ advanced/microbeam:
|
|
o Improved dose calculation in the code in order to take into account
|
|
small energy deposits by any particle around the phantom edge voxels,
|
|
by suppressing a selection condition on the PostStep. The total result
|
|
of the dose calculation does not change significantly.
|
|
o Added protection against scattering at large angles in collimators.
|
|
o Suppressed field manager in zones with zero field.
|
|
o Use 'kUndefined' optimization in cell phantom implementation.
|
|
o Changed number of incident alpha particles in microbeam.mac.
|
|
+ advanced/underground_physics:
|
|
o Added missing header file G4hIonisation.hh to DMXPhysicsLists
|
|
translation unit.
|
|
o Added G4StepLimiter to physics list as correction of migration
|
|
required since Geant4 release 7.0.
|
|
+ extended/electromagnetic/TestEm7:
|
|
o Updated README for physics-list names.
|
|
+ extended/electromagnetic/TestEm8:
|
|
o Fixed PAI physics constructors: energy loss processes should be
|
|
active post step.
|
|
o Create VisManager only for interactive session, improved destructor
|
|
of Em8DetectorConstruction class.
|
|
+ extended/electromagnetic/TestEm10:
|
|

|
|
of Em10DetectorConstruction class.
|
|
+ extended/electromagnetic/TestEm13:
|
|
+ extended/electromagnetic/TestEm14:
|
|
o SteppingAction : modify logic to take into account low energy packages.
|
|
+ extended/medical/fanoCavity:
|
|
o Use 'fUseDistanceToBoundary' in physics-list for 'emOptions'. Cleanup.
|
|
+ extended/medical/GammaTherapy:
|
|
o Provide possibility to change cuts between runs.
|
|
+ extended/radioactivedecay/exrdm:
|
|
o Removed obsolete hadronic builders and use only QGSP_BIC,
|
|
QGSP_BIC_HP, QGSP_BERT, QGSP_BERT_HP instead.
|
|
+ novice/N02:
|
|
o Fixed implementation of ExN02MagneticField class in way field is set.
|
|
