Geant4 8.0 - patch-01 Release Notes
|
|
-----------------------------------
|
|
|
|
10 February 2006
|
|
|
|
List of fixes included in this public patch since the public release 8.0:
|
|
|
|
o Digits & Hits:
|
|
-------------
|
|
+ Added missing methods in G4VDigiCollection and G4TDigiCollection.
|
|
Addresses problem report #786.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ divisions
|
|
o Added missing setting of mother-logical pointer in constructors of
|
|
G4PVDivision. Fixes problem report #829.
|
|
o Added missing checks for illegal constructs of G4PVDivision (NULL
|
|
pointer to mother logical and self-placement).
|
|
o Fixed check for generic construct in G4ParameterisationPolycone and
|
|
G4ParameterisationPolyhedra: allow it for the automatic replicated
|
|
instance.
|
|
o Cache information about axis of division and provided accessor method
|
|
GetDivisionAxis() in G4PVDivision.
|
|
+ navigation
|
|
o Addressing problem with convergence in LocateIntersectionPoint()
|
|
of G4PropagatorInField. The problem, identified by Atlas, was
|
|
observed when requesting high precision, i.e. small values of
|
|
eps_min/max, delta_one_step, due to need for small delta_intersection.
|
|
Increased maximum iterations (from 100 to 10000) until correct
|
|
information can be return an Exception is thrown in case of too many
|
|
iterations; a warning is thrown in case over 1000 iterations.
|
|
+ solids/BREPS
|
|
o Use explicit 'HepGeom' namespace for 'Identity', to allow for
|
|
porting on Windows/VC++ when using CLHEP-2.0.X.
|
|
+ solids/CSG
|
|
o G4Sphere: fixed bug in DistanceToOut() for theta intersections.
|
|
Fixes problem report #830.
|
|
+ solids/specific
|
|
o Fixed visibility of soft edges for visualization of twisted solids.
|
|
o G4TwistedTubs and G4VTwistedFaceted::CreatePolyhedron(): changed
|
|
parameterised polyhedron mesh approximation in terms of
|
|
G4Polyhedron::GetNumberOfRotationSteps().
|
|
o Fixes in G4EllipticalCone:
|
|
- Changed GetPointOnSurface(), which was not uniform in endcaps.
|
|
- Bug fix in Inside(), which was not correct for the elliptic mantel.
|
|
Made test similar as in G4EllipticTube.
|
|
- Several fixes in DistanceToIn/Out() resolving problems of looping
|
|
events.
|
|
+ volumes
|
|
o G4AssemblyVolume: fixed initialisation of names for placed volumes
|
|
which was corrupted after migration to <sstream> as side effect.
|
|
|
|
o Particles:
|
|
---------
|
|
+ Bug fix for G4ParticleDefinition, was causing improper behavior of
|
|
GetAtomicNumber() method for ions. Fixes problem report #827.
|
|
|
|
o Electromagnetic processes:
|
|
-------------------------
|
|
+ standard:
|
|
o Fix in G4PolarizedComptonScattering, returning PostStepDoIt()
|
|
for G4ComptonScattering52. Fixes problem report #478.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ management:
|
|
o G4HadronicProcess: fixed problem report #611. Problems caused when
|
|
hadronic interactions reset stopButAlive particle to Alive.
|
|
o Added diagnostics when hadronic exceptions occur in G4HadronicProcess
|
|
and G4EnergyRangeManager.
|
|
+ models/binary_cascade:
|
|
o Fixed problem report #794. Projectile nucleus needs to be centered.
|
|
+ models/chiral_inv_phase_space/body:
|
|
o Fixed trivial compilation warning.
|
|
+ models/de_excitation:
|
|
o G4NuclearLevelManager: print a warning if no data file is present.
|
|
Addressed problem report #814.
|
|
o G4ParaFissionModel: fix for compilation error, following problem
|
|
report #817.
|
|
+ models/neutron_hp:
|
|
o Fixes core dump observed when neutron energy is close to 20 MeV.
|
|
+ models/radioactive_decay
|
|
o G4NuclearDecayChannel::BetaDecayIt(): check for negative sqrt()
|
|
argument in 'daughtermomentum[1]'. Fixes problem report #822.
|
|
+ stopping:
|
|
o Set process type to be 'fHadronic'. Was not set previously.
|
|
+ util:
|
|
o G4ReactionDynamics: added array bounds protection in TwoCluster().
|
|
|
|
o Processes cuts:
|
|
--------------
|
|
+ Fix in G4VRangeToEnergyConverter::Convert() to recalculate the energy
|
|
loss table if new elements are added. Fixes problem report #831.
|
|
|
|
o Track:
|
|
-----
|
|
+ G4ParticleChangeForRadDecay is now derived from G4ParticleChangeForDecay.
|
|
|
|
o Transportation:
|
|
--------------
|
|
+ G4Transportation: the particle's charge is now taken from the dynamic
|
|
particle, so that it can take into account changes from the interaction
|
|
of an ion with matter (eg stripping e-).
|
|
+ Corrected problem with suspended tracks, addressing problem report #802.
|
|
Added StartTracking() method which takes over responsibility to clear
|
|
the state for a new track, and to message other relevant component to
|
|
clear their state.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ management:
|
|
o Fixed bug that omits geometry volumes from file-based visualization
|
|
drivers for first /run/beamOn.
|
|
o Added friend status for ray-tracer.
|
|
+ RayTracer:
|
|
o Fix behavior of messengers when RayTracerX is used.
|
|
o Allow for multiple ray tracers.
|
|
o Separated out the original ray tracer to be used by viewers.
|
|
|
|
o Data:
|
|
----
|
|
+ New data set for high-precision neutron processes G4NDL-3.8
|
|
o Added Gadorinium data (source ENDF/B-VI).
|
|
o Replaced: Inelastic/CrossSection/17_nat_Chlorine and
|
|
Inelastic/F10/28_62_Nickel (source ENDF/B-VI).
|
|
o Removed: Inelastic/CrossSection/32_70|72|73|74|76_Germanium
|
|
|
|
o Examples:
|
|
--------
|
|
+ Updated reference outputs.
|
|
+ extended/electromagnetic/TestEm7
|
|
o Trivial fix of memory leak.
|
|
+ extended/medical/GammaTherapy
|
|
o Substituted PreciseRange with CSDARange.
