|
|
|
|
o Global:
|

|
temporaries. Removed obsolete static hash(s) method in G4String.
|
|

|
|
in G4MuonRadiativeDecayChannelWithSpin.
|
|
|
|
o Standard Electromagnetic Processes:
|
|
----------------------------------
|

|
|
value of transfered energy in G4MuPairProductionModel.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ cross_sections:
|
|
o G4IonsKoxCrossSection, G4IonsShenCrossSection, G4TripathiCrossSection,
|
|
G4TripathiLightCrossSection: added protections against numerical
|
|
exceptions. Added simple check that cross-section is positive and
|
|
removed not optimal control in G4TripathiLightIonCrossSection class.

|
|
G4NeutronHPInelasticCompFS.
|
|
+ models/parton_string:
|
|
o Fix in G4SPBaryon for anti-baryon: a diquark & quark was given instead
|
|
of anti-diquark & antiquark; note the reverse order, too.
|
|
Fixes problems with incident anti-baryons, e.g. anti-proton,
|
|
manifesting in problems with forming hadrons.
|
|
o Changed pt sampling in G4LundStringFragmentation to avoid near endless
|
|
loop; this should improve overall performance slightly.
|
|
Addresses problem report #1066. Affected G4VLongitudinalStringDecay,
|
|
where SampleQuarkPt() is implemented; added new optional argument of
|
|
max Pt to SampleQuarkPt().

|
|
applying QGSC from zero energy.
|
|
+ models/qmd:

|
o Changed object data member to pointer in G4QMDReaction.
|
|
+ models/rpg:
|
|
o Removed global variables (pointers to static particle definitions) in
|
|
G4RPGInelastic and replaced with local array. Fixing issues of wrong
|
|
order for static initialization.
|
|
+ processes:
|
|
o Fix to address problem report #1056: cross section data set now are
|
|
created dynamically in G4PhotoNuclearProcess, G4ElectronNuclearProcess
|
|
and G4PositronNuclearProcess.
|
|
o Moved inline constructor and destructors to source in class
|
|
G4PositronNuclearProcess.
|
|
|
|
o Generic Processes:
|
|
-----------------
|
|

|
|
G4VRangeToEnergyConverter.
|
|
o Replaced usage of std::abs() with std::fabs() where appropriate.
|
|
+ Optical:
|
|
o Fix in G4OpBoundaryProcess for complex index of refraction: resample
|
|
the reflectivity every time for DielectricMetal, and do not re-calculate
|
|
normal to facet; also fixed possible infinite loop by resetting iTE and
|
|
iTM inside GetReflectivity().
|
|
o Added exception for cases where invalid normal is returned;
|
|
following problem report #1060.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ gdml:
|
|
o Defined missing copy constructor and operator=() to G4GDMLMatrix
|
|
internal class, to avoid cases of memory corruption when handling
|
|
matrices.
|
|
o Correction in materials and solids tags for allowing parsing of
|
|
definitions within the tag scope; possibility foreseen by the schema.
|
|
o Correction in G4GDMLWriteSolids::BooleanWrite() in order to handle
|
|
cases of nested displaced solids given to both operands in a Boolean
|
|
operation (ATLAS use case).
|
|
o Renamed flag for maximum number of transformations applied to a solid
|
|
and moved to G4GDMLWriteSolids base class.
|
|
o First virtual layer for custom writer classes; added empty default
|
|
constructor and virtual destructor to classes in new inheritance chain.
|
|
o Restricted usage of loops only for placement of volumes. Now correctly
|
|
handling most common use-case of multiple copies of the same
|
|
volume/solid through loop statement. Addressing problem report #1063.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ Fix to address problem report #1056: all cross section data sets are
|
|
created dynamically and no longer member of the class.
|
|
Fix in G4HadronInelasticQBBC: cross sections are created dynamically
|
|
not by value, fission only instantiated for HP.
|
|
+ Inline constructor and destructors are moved to source for classes:
|
|
G4VNeutronBuilder, G4VPiKBuilder, G4VProtonBuilder, G4WarnPLStatus.
|
|
|
|
o Visualization:
|
|
-------------
|
|
