Geant4 8.1 - patch-02 Release Notes
|
|
-----------------------------------
|
|
|
|
10 November 2006
|
|
|
|
List of fixes included in this public patch since the public release 8.1.p01:
|
|
|
|
o Geometry:
|
|
--------
|
|
+ management
|
|
o Added empty virtual method CheckOverlaps() to G4VPhysicalVolume to
|
|
allow for proper overloading from subclasses. Implementation returns
|
|
always 'false', which is the case for replicas.
|
|
|
|
o Global:
|
|
------
|
|
+ Corrected inclusion of CLHEP headers in wrapper files
|
|
G4SystemOfUnits.hh and G4PhysicalConstants.hh.
|
|
|
|
o Electromagnetic processes:
|
|
-------------------------
|
|
+ standard:
|
|
o Fixed energy non-conservation in G4PAIModel for positrons. Fix also
|
|
concerning 'Tmax' for electrons and positrons: 'Tmax' is defined
|
|
now for each particle independently.
|
|
o Fixed problem of positron zero incident energy in G4eeToTwoGammaModel.
|
|
o Added extra protection inside G4BetheBlochModel.
|
|
o Fixed problems and add comments in the classes prototype Coulomb
|
|
elastic scattering: G4CoulombScattering, G4CoulombScatteringModel,
|
|
G4eCoulombScatteringModel. Set default limit on scattering angle to
|
|
zero.
|
|
+ utils:
|
|
o G4VEnergyLossProcess: made LambdaPhysicsVector() method protected.
|
|
o G4ionEffectiveCharge: added protection for NULL pointer to material.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ models/coherent_elastic:
|
|
o Introduced NaN check inside G4HadronElastic, G4ChargeExchange, and
|
|
G4UHadronElasticProcess.
|
|
o Removed HP data from G4UHadronElasticProcess (it is set in physics
|
|
lists); added low energy threshold of 20 MeV in G4HadronElastic for
|
|
QElastic. For any particle with kinetic energy below 10 KeV, the
|
|
primary particle is returned unchanged and no scattering is sampled.
|
|
This prevents situations of low-energy neutrons scattering forever,
|
|
and reduces precision in computing scattering for low-energy hadrons.
|
|
+ models/utils:
|
|
o Reduced warning output from G4Fragment on negative excitation energy;
|
|
a maximum of 10 warnings is printed now.
|
|
o G4Fancy3DNucleus:ChoosePositions(): correctly use std::vector.
|
|
Correction addressing problem report #887 on WIN32/VC8.
|
|
o Removed meaningless 'const' qualifier from return type of method
|
|
G4Fancy3DNucleusHelper().
|
|
|
|
o Particles:
|
|
---------
|
|
+ Fixed bug in G4ParticleDefinition constructor causing not filling quark
|
|
contents when G4VERBOSE is not set.
|
|
+ Fixed bug in k2(1770) decay. Addresses problem report #894.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ Get Rid of useless forward declarations in G4MCTEvent and
|
|
G4MCTGenParticle header files. Clearing compilation warnings on
|
|
icc-9.X compilers.
|
|
|
|
o Track:
|
|
-----
|
|
+ Made G4StepPoint::operator=() inline for optimisation.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ G4HadronElasticPhysics: added explicit inclusions of data headers
|
|
in the header file.
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ Linux-icc: updated setup to support Intel icc compiler 9.X series.
|
|
+ liblist.c: added .dylib search for list of libraries.
|
|
Addressing problem report #885.
|
|
+ architecture.gmk: added variables for commands: echo, cat, cut, sed;
|
|
to be eventually overloaded in system dependent configurations.
|
|
Overloaded variables for WIN32-VC to force usage of the original
|
|
CygWin built-in commands. Use standard 'echo' command for Darwin-g++.
|
|
Replaced system commands with variables defined at architecture level
|
|
in source/GNUmakefile.
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
|
|
+ advanced/underground_physics
|
|
o Fixed bug: removed uninitialized 'UserLimitsForXenon'.
|
|
+ extended/analysis/AnaEx01
|
|
o Corrected text in README for AIDA setup.
