28 June 2019
|
|
|
|
Migration Notes & Main New Features
|
|
-----------------------------------
|
|
|
|
o Promoting pre-processor flags to fixed #defines in a new header
|
|
generated by CMake, reducing flags added to CMAKE_CXX_FLAGS.
|
|
o Reviewed G4PhysicsVector adding an additional Value() method option to
|
|
propagate down the known log-energy value. This helps avoiding log() calls
|
|
when log-vector is used.
|
|
o Enabled VecGeom wrapper for G4GenericPolycone. Requiring VecGeom-1.1.2.
|
|
o Added support for writing out assemblies envelopes in GDML.
|
|
o Added functionality in G4DynamicParticle to provide log-kinetic energy
|
|
value, computed only on demand if its stored value is not up-to-date with
|
|
the kinetic energy. Reviewed EM processes to select the target atom by
|
|
making use of the already known log-energy value in the log-vector access.
|
|
Providing measurable CPU speedup.
|
|
o Optimised step limitation in G4UrbanMscModel and modified lateral
|
|
displacement sampling.
|
|
o New helper class G4NIELCalculator, to compute NIEL in user stepping
|
|
action or sensitive detector code.
|
|
o Cross-sections: high energy extension of the neutrino-electron cross
|
|
sections, for both charged-current and neutral-current interactions
|
|
(M_W and M_Z propagator factors and Glashow resonance), for all neutrino
|
|
and anti-neutrino flavours.
|
|
o Extended hadron-nucleon cross-sections to charmed and bottom hadrons
|
|
(mesons and baryons).
|
|
o Use Glauber-Gribov cross-section for hyperons in hadron elastic physics.
|
|
o Added handling of UI thermalization model control in DNA physics lists.
|
|
o Removed tracking cut in hadron-elastic and use numerically safer
|
|
computation for very low-energy projectile.
|
|
o Use FTFP also for the annihilation at rest of neutral anti-hadrons.
|
|
o Added spontaneous fission channel in radioactive-decay.
|
|
o Enhanced UI commands to now return proper return code when they are not
|
|
successful.
|
|
o Added new gamma-nuclear model based on pre-compound de-excitation
|
|
o New set of UI commands and improvements in visualization.
|
|
Added new UI commands for view interpolation and centering.
|
|
o Introducing cloud drawing style in visualization, using kernel algorithms
|
|
for generating points on the surface of volumes, by-passing polyhedral
|
|
representations; the solid is being visualised by a polymarker of dots.
|
|
o Porting of code on gcc-9.1 series.
|
|

|
+ CMake:
|
|
o Removed obsolete GEANT4_BUILD_MUONIC_ATOMS_IN_USE option
|
|
and associated configuration/compiler flags.

is either greater than 1.0 or smaller than -1.0 (in the first case, we
|
|
assume no interaction and the projectile keeps going unchanged; in the
|
|
second case, we assume that the projectile stops and its kinetic energy
|
|
is deposited locally, neglecting the recoil of the target nucleus).

|
|
G4VEmissionProbability, G4PhotonEvaporation, G4PolarizationTransition:

|
|
initialisation, 2- debug printout, 3- very detailed debug printout.

o Fixed in G4NuMuNucelusCc(Nc)Model for kinematics of quasi-elastic
|
|
neutrino scattering.
|
|
+ models/management
|
|
o G4HadronicInteractionRegistry: fixed typo in comments, removed unused
|
|
Boolean flag.
|
|
+ models/particle_hp
|
|
o Fix to deal with incorrect excitation energy when charged particles are
|
|
emitted during neutron reaction. In G4ParticleHPInelasticCompFS,
|
|
changed method CompositeApply(), for very small excitation, change
|
|
level index from -1 to 0 only if incident and outgoing particles are
|
|
the same. Addressing problem report #1838.
|
|
o Fix to deal with un-incremented index of photons in
|
|
G4ParticleHPPhotonDist::GetPhotons(). Also cleaned up dead code
|
|
in that class. Addressing problem report #2167.
|
|
o G4ParticleHPChannelList: fixed bug in the momentum change (it has to
|
|
be a normalized 3-vector, but it was not) in the case where NeutronHP
|
|
could not find a proper reaction channel.
|
|
o G4ParticleHPInelasticCompFS: fix to avoid arbitrary number of target
|
|
nuclei being generated and slowing down multi-threaded operation.
|
|
Addressing problem report #2166.
|
|
+ models/pre_equilibrium
|
|
o Added new model based on pre-compound de-excitation
|
|
G4LowEGammaNuclearModel.
|
|
o G4PreCompoundEmission, G4PreCompoundFragment, G4VPreCompoundFragment:
|
|
setup minimum number of points for probability integration to 4;
|
|
minor code clean-up.
|
|
+ models/radioactive_decay
|
|
o Added spontaneous fission channel: added new class G4SFDecay to handle
|
|
neutron and gamma generation using LLNL model. Read spontaneous fission
|
|
data from database, insert it into decay tables and instantiate
|
|
G4SFDecay.
|
|
o Fixed incorrect branching ratio sum for biased mode, to account for the
|
|
addition of N shell EC capture and spontaneous fission.
|
|
o G4RadioactiveDecayBase: added StreamInfo() method; updated to new
|
|
N shell EC; enable printout of parameters with G4VERBOSE in
|
|
BuildPhysicsTable().
|
|
o G4RadioactivationMessenger: removed obsolete "fast beta" option,
|
|
internal conversion option (not part of biasing) and atomic relaxation
|
|
option (not part of biasing). Added "analogueMC" option which was
|
|
forgotten when class was developed.
|
|
o G4RadioactiveDecayBaseMessenger: removed obsolete "fast beta" option.
|
|
o Replaced G4ExceptionDescription in loop with simple string at
|
|
exception time inG4RadioactiveDecay, G4RadioactiveDecayBase and
|
|
G4Radioactivation.
|
|
o In G4RadioactiveDecay::CalculateChainsFromParent() and
|
|
G4Radioactivation::CalculateChainsFromParent(), fixed memory leak of
|
|
'summedDecayTable' reported by Coverity.
|
|
o G4RadioactiveDecay, G4RadioactiveDecayBase: make sure decay table maps
|
|
are cleanly deleted at the end of program.
|
|
+ models/util
|
|
o G4NuclearRadii: new utility class with several parameterisations of
|
|
nuclear radius.
|
|
+ processes
|
|
o G4HadronElasticProcess: removed tracking cut for all particles (charged
|
|
particles may be stopped by the tracking cut of ionisation process;
|
|
neutrons should be stopped by G4NeutronKiller).
|
|
Added protection for zero energy primary. Removed final state rotation.
|
|
Removed default GHEISHA cross-section.
|
|
Clean up sampling of final state; improved description and comments;
|
|
added C++11 keywords; removed unused local members.
|
|
o G4MuNeutrinoNucleusProcess : new process managing
|
|
G4NuMuNucleusCc(Nc)Model models.
|
|
+ stopping
|
|
o G4HadronicAbsorptionFritof: extended to neutral anti-hadrons
|
|
(anti-neutron, anti-lambda, anti-sigma0 and anti-xi0). This extension
|
|
is for completeness and practical convenience, although physically
|
|
neutral hadrons should never be completely at rest.
|
|
+ util
|
|
o G4HadProjectile: clean-up for small kinetic energy of the projectile.
|
|
o G4HadFinalState, G4Bessel, G4ReactionProduct, G4GHEKinematicsVector:
|
|
replaced fabs() with abs().
|
|
|
|
o Track & Tracking
|
|
----------------
|
|
+ G4Track: added forward declaration for G4VProcess.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ Fixed compilation warnings on gcc-9.1.0.
|
|
+ management:
|
|
o Introducing cloud drawing style. New parameter candidate 'cloud' in
|
|
"/vis/viewer/set/style". Cloud drawing uses solid->GetPointOnSurface(),
|
|
i.e., uses kernel algorithms and by-passes polyhedral representations.
|
|
The solid is represented by a polymarker of dots. The default number of
|
|
points is 1000. This can be changed with the command
|
|
"/vis/viewer/set/numberOfCloudPoints"; the minimum number is 100.
|
|
Note that OpenGL has a fast algorithm for polymarker.
|
|
This allows us to use cloud style both as a choice or as fallback when
|
|
the polyhedral representation fails, for example, when BooleanProcessor
|
|
fails.
|
|
o New and improved commands:
|
|
/vis/viewer/centreOn: improved - it does not zoom.
|
|
/vis/viewer/centreAndZoomInOn: new.
|
|
/vis/touchable/centreOn: improved - it does not zoom.
|
|
/vis/touchable/centreAndZoomInOn: new.
|
|
/vis/touchable/extentForField and volumeForField: new.
|
|
/vis/scene/showExtents: new.
|
|
/vis/set/volumeForField: new.
|
|
/vis/touchable/showExtent: new.
|
|
o Added copy number parameter to "/vis/touchable/findPath".
|
|
o Implemented "/vis/set/extentForField" command: the default is a null
|
|
extent, which is to be interpreted by the field model as the whole
|
|
extent of the current scene. Otherwise, with this command, one can
|
|
limit the extent over which the field is drawn. This would help, for
|
|
example, if drawing over the whole scene produced so many arrows or
|
|
lines that it clutters the scene. Changed the default spacing:
|
|
the parameter 'nDataPointsPerHalfExtent' is changed from 10 to 3, so
|
|
as not to clutter the scene. See guidance of "/vis/scene/add/*Field"
|
|
commands for further explanation.
|
|
o Provide ability to draw electric fields, and eventually any other
|
|
field. Added "/vis/scene/add/electricField" by analogy to existing
|
|
.../magneticField.
|
|
o Refactor MagneticFieldModel class with new base to handle all kinds of
|
|
vector fields; existing, and new ElectricFieldModel only have to
|
|
implement a simple function to get the field vector at a location.
|
|
o Include parameterised volumes in overlap checking and visualisation
|
|
in G4LogicalVolumeModel (in addition to ordinary placements).
|
|
o Introduced "/vis/viewer/centreOn" and "/vis/touchable/centreOn" UI
|
|
commands. This allows one to centre the view (zoom in) on a volume.
|
|
Reset with "/vis/viewer/reset".
|
|
o Rationalised view interpolation; encapsulate algorithm into base class
|
|
G4VVisCommand, so that commands "/vis/viewer/interpolate",
|
|
"/vis/viewer/centreOn" and "/vis/touchable/centerOn" now use this.
|
|
Might consider use by all view changing commands.
|
|
o Fixed bug in "/vis/viewer/set/sectionPlane".
|
|
o Corrected few typos in printout/comments.
|
|
o Improved guidance for "/vis/scene/add/volume".
|
|
o Minor improvements to visualization manager.
|
|
o Fixed Boolean operators to return G4bool.
|
|
o Fixed Coverity defects.
|
|
+ modeling:
|
|
o Introduced G4BoundingExtentScene. This allows one to accumulate extents
|
|
using the newly introduced G4VisExtent::Transform() and is a better way
|
|
of determining the overall extent of a scene (or of any set of extents)
|
|
than by the bounding sphere approach.
|
|
o G4VFieldModel, G4ElectricFieldModel, G4MagneticFieldModel: new
|
|
abstraction for field models.
|
|
o Arrows and field models: introduced further protection.
|
|
o G4VModel: introduced GetTransformedExtent() method.
|
|
o G4PhysicalVolumeModel: use G4BoundingExtentScene instead of
|
|
G4BoundingSphereScene. Fixed bug whereby the local extent was
|
|
incorrectly calculated.
|
|
o Fixed bug in "/vis/viewer/set/sectionPlane".
|
|
o Added volume count (but commented out printing).
|
|
+ OpenGL:
|
|
o Force double buffer context for OGLIX.
|
|
o Force kernel visit on change of number of cloud points.
|
|
o Fixed bug in "/vis/viewer/set/sectionPlane".
|
|
o Avoid re-using display lists for markers. They may have their own
|
|
position relative to the overall object transformation.
|
|
+ OpenInventor:
|
|
o Test number of cloud points for kernel visit.
|
|
o Added missing protection on G4VIS_BUILD_OIX_DRIVER.
|
|
o Fixed compilation warning from gcc-9.1 in SoCounterAction for setting
|
|
of name, apparently not allowed in OpenInventor.
|
|
o Corrected few typos in printout/comments.
|
|
+ XXX:
|
|
o Force kernel visit on change of number of cloud points.
