|
|
where Geant4 installs its own. Force to install its headers under
|
|

|
|
+ ptl: apply patch to fix component installs on Windows.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ navigation:
|
|
o G4ReplicaNavigation: reduced step correction in ComputeStep().
|
|
Addressing problem report #2302.
|
|
o G4PathFinder: moved debug printout within debug block in Locate().
|
|
o G4RegularNavigation: protected within G4DEBUG_NAVIGATION debug printout.
|
|
Substituted warning printout with proper G4Exception.
|
|
+ solids/Boolean:
|
|
o Added protection against using invalid normal
|
|
in G4ScaledSolid::DistanceToOut(p,v).
|
|
+ solids/CSG:
|
|
o G4Trap, G4Para: removed spurious character in printout in StreamInfo().
|
|
Addressed problem report #2318.
|
|
+ solids/specific:
|
|
o Reduce cases of bad speculation in G4PolyhedraSide::Inside() and
|
|
G4PolyPhiFace::InsideEdges(), based on profiling analysis.
|
|
+ volumes:
|
|
o Added creation order index in G4LogicalBorderSurface.
|
|
Addressing problem report #2311.
|
|
o G4GeometryWorkspace: added protection for thread contention in function
|
|
DestroyWorkspace(). Some code cleanup.
|
|
|
|
o Global:
|
|
------
|
|
+ Updated date and version for 10.7.p01.
|
|
|
|
o Intercoms:
|
|
---------
|
|
+ G4UImanager: introduced flag and access functions for
|
|
LastCommandOutputTreated. This flag is set to false at the point
|
|
in ApplyCommand() where, if verbosity>0, the command is sent to G4cout.
|
|
The treating UI must reset to true when the line has been treated.
|
|
Of course, the UI may simply ignore it.
|
|
|
|
o Interfaces:
|
|
----------
|
|
+ G4UIQt: Use QPalette to get colour and background from OS;
|
|
instead of fixed background <span style='background:#EEEEEE...
|
|
use <span style='background:" + pal.highlight().color().name()...
|
|
This picks up colour from the OS and even allows for change of
|
|
OS display style, e.g., dark mode on MacOS.
|
|
Fixed command-line-echo highlighting whereby there could be a crash
|
|
in some circumstances: use <span> instead of <div> in HTML wrappers.
|
|
+ Introduce choice of output styles:
|
|
o /gui/outputStyle
|
|
<cout|cerr|warnings|errors|all>
|
|
<fixed|proportional>
|
|
<highlight|no-highlight>
|
|
o Highlighting applies to the echoed command line if echoing is
|
|
requested with /control/verbose > 0.
|
|
|
|
o Persistency - gdml:
|
|
------------------
|
|
+ Fix for proper treatment of material properties reading for skinsurface
|
|
and bordersurface elements; adopt the key of the property vector map as
|
|
'name + ref'. Addressing problem report #2305.
|
|
+ Fixed parsing of regions in G4GDMLParser::ImportRegions().
|
|
Allow for proper deletion of meta-data lists in destructor.
|
|
Based on GitHub PR#19.
|
|
+ Fixed reading of units for GenericTrap in G4GDMLReadSolids.
|
|
Addressing problem report #2317.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ builders
|
|
o G4HadronicBuilder: replaced 2-body decays of bottom mesons into charmed
|
|
mesons and charged rho resonance, with 3-body decays into the same
|
|
charmed mesons and charged pion and neutral pion. This allows to get a
|
|
more precise numerical treatment of the decay kinematics in the rest
|
|
frame, avoiding spurious energy-momentum violations reported by
|
|
G4DecayProducts.
|
|
o OrderingParameterTable: added forgotten processes (general positron,
|
|
surface reflection, DNA) coherently with G4PhysicsListHelper.
|
|
+ constructors/electromagnetic
|
|
o G4GammaGeneralProcess: changed 1st energy limit from 50 keV to 150 keV
|
|
to guarantee K-shell energy for any element to be within 1st energy
|
|
area. Changed logic for selection of a concrete process.
|
|
Maximally reduced use of 'if' statements; reduced number of 'return'
|
|
in run time methods; removed shadowing of base class methods.
|
|
Addressing problem report #2309.
|
|
+ constructors/hadron_elastic
|
|
o G4HadronElasticPhysics: fixed type of builder in all hadron elastic
|
|
constructors. Addressing problem report #2183.
|
|
o G4IonElasticPhysics, G4ThermalNeutrons: added comments
|
|
+ constructors/hadron_inelastic
|
|
o G4HadronPhysicsFTFP_BERT, G4HadronPhysicsQGSP_BERT,
|
|
G4HadronInelasticQBBC, G4HadronPhysicsQGSP_BIC: fixed type of builder
|
|
in all hadron inelatic constructors. Addressing problem report #2296.
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ lowenergy
|
|
o G4MicroElecSurface, G4MicroElecLOPhononModel: fixed Coverity defects.
|
|
+ standard
|
|
o G4BetheBlochModel, G4LindhardSorensenIonModel: restore computation of
|
|
maximum energy transfer as in Geant4 version 10.4; affecting only
|
|
ultra-relativistic ions. Addressing problem report #2312.
|
|
+ utils
|
|
o G4EmCorrections: fixed 2-D interpolation of shell corrections, which
|
|
provides minor change of ranges of charge particles (< 0.1 mm).
|
|
Addressing problem report #2308.
|
|
o G4VEnergyLossProcess, G4VEmProcess, G4EmExtraParameters and
|
|
G4EmExtraParametersMessenger: improved printout.
|
|
Addressing problem report #2292.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ cross_sections:
|
|
o Drop cache for per-element G4CrossSectionDataStore::GetCrossSection(),
|
|
as never used in practice. Note that material, particle, and energy are
|
|
still cached by G4CrossSectionDataStore::ComputeCrossSection(). The
|
|
condition to check for the cache in that case has been optimized to
|
|
minimize unnecessary checks by reordering checked conditions from most
|
|
to least discriminant.
|
|
o G4ParticleInelasticXS, G4CrossSectionInelastic, G4CrossSectionElastic:
|
|
extended maximum energy range for ion cross-sections (QBBC and other
|
|
Physics Lists has the same high energy limits).
|
|
o G4ParticleInelasticXS, G4NeutronCaptureXS, G4NeutronElasticXS,
|
|
G4NeutronInelasticXS: make MAXZ variable static class member.
|
|
o G4GammaNuclearXS: fixed duplicated name of static variable.
|
|
o G4VCrossSectionRatio: use inheritance from G4VCrossSectionDataSet
|
|
in order to guarantee deletion of the object at the end of run.
|
|
+ models/particle_hp
|
|
o G4ParticleHPThermalScattering: added final state phi-rotation.
|
|
Addressing problem reports #1856 and #2290.
|
|
+ stopping
|
|
o G4MuonicAtomDecay: fixed Coverity defects; removed commented code.
|
|
|
|
o Processes - Transportation
|
|
--------------------------
|
|
+ Limit reporting of number of calls to G4Transportation::AlongStepDoIt()
|
|
to when either G4VERBOSE or G4DEBUG_TRANSPORT is defined, which allows to
|
|
avoid using a thread local variable for a slight performance gain.
|
|
|
|
o Run:
|
|
---
|
|
+ G4PhysicsListHelper: added forgotten processes (general positron and
|
|
surface reflection).
|
|
|
|
o Tasking:
|
|
-------
|
|
+ G4WorkerTaskRunManager: corrected way to count the number of events
|
|
processed in a worker thread. This correction also fixes a rare crash
|
|
due to accessing to the seed vector more than necessary.
|
|
+ G4TaskRunManager: reduce number of events per task to evenly distribute
|
|
events to all available threads.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ OpenInventor
|
|
o Consolidated all the planned features of the OIQt viewer.
|
|
+ Qt3D
|
|
o Auxiliary edge suppression and some small improvements.
|
|
|
|
o Data Sets:
|
|
---------
|
|
+ G4PARTICLEXS-3.1.1:
|
|
o Fixed data for He3 and He4 for few light targets.
|
|
|
|
o Examples:
|
|
--------
|
|
+ basic/B4:
|
|
o Fixed README: updated visualization tutorial to follow smart parsing.
|
|
+ extended/persistency/gdml/G01:
|
|
o Fixed auxiliary.gdml sample to define proper Region tags.
|
|
o Added scaledSolids.gdml sample setup.
|
