This file should be used by G4 developers and category coordinators

to briefly summarize all major modifications introduced in the code

and keep track of all category-tags.

It DOES NOT substitute the CVS log-message one should put at every

|
||||
G4FastSimulationManagerProcess class:
|
||||
Fixes made for ghost navigation with
|
||||
mag-field:
|
||||
LocateGlobalPointAndUpdateTouchable is
|
||||
always used (in not the Locate...Setup
|
||||
method)
|
||||
In PostStepDoIt: correction of position and
|
||||
direction of the track are made when
|
||||
possible in case of mag-field.
|
||||
This correction comes from the fact that a
|
||||
small discrepancy appears on those quantities
|
||||
because of the numerical integration along
|
||||
the field on the track path: the G4FSMP
|
||||
proposes a curve-length, the transportation
|
||||
moves the track along this curve, however
|
||||
the end point position and direction are
|
||||
slightly different from those expected by
|
||||
the G4FSMP when it proposed the length.
|
||||
|
||||
November 20,1998 M. Verderi
|
||||
G4FastStep class:
|
||||
Remove track/G4BiasingTag.hh dependancy (obsolete).
|
||||
Adapted to new shceme of Event Biasing mechanism,
|
||||
consistently with track-00-04-01 tag.
|
||||
|
||||
November 11,1998 M. Verderi
|
||||
Merge of param-00-03-02 & param-00-03-02a into
|
||||
param-00-03-04a (hopefully...)
|
||||
The point is the chnage of signature in the
|
||||
LocateGlobalPointAndSetup(..) of the G4Navigator making use now
|
||||
of the track direction. The G4FastSimulationManagerProcess is
|
||||
changed accordingly:
|
||||
fGhostNavigator.LocateGlobalPointAndSetup(track.GetPosition(), &direction, true);
|
||||
|
||||
|
||||
November 6, 1998 M. Verderi
|
||||
- Extension of the G4FastStep to allow the biasing technic.
|
||||
Changes are made in:
|
||||
- G4FastStep.hh/.icc:
|
||||
new member G4BiasingTag fBiasTag;
|
||||
new method SetPrimaryTrackFinalBiasingTag
|
||||
( G4BiasingTag aTag );
|
||||
- G4FastStep.cc:
|
||||
Initialize();
|
||||
operator=;
|
||||
UpdateForPostStep();
|
||||
UpdateForAtRest();
|
||||
|
||||
October 26, 1998 P.Mora de Freitas
|
||||
- G4FastSimulationManagerProcess and G4FastSimulationManager adapted to deal
|
||||
with at rest parameterisations also when using parallel geometry.
|
||||
|
||||
October 8, 1998 P.Mora de Freitas
|
||||
- The G4VFastSimulationModel::IsApplicable() becomes a pure virtual
|
||||
methode.
|
||||
- G4FastSimulationManager optimisation:
|
||||
- New G4ParticleDefinition* fLastCrossedParticle data member, keeps
|
||||
the last particle type with touched the envelope;
|
||||
- New RWTPtrOrderedVector<G4VFastSimulationModel> fApplicableModelList
|
||||
data member, keeps the model list of the applicable models for
|
||||
the actual fLastCrossedParticle particle type;
|
||||
- Changes in the PostStepGetFastSimulationManagerTrigger() and
|
||||
AtRestGetFastSimulationManagerTrigger()methodes to update the
|
||||
fApplicableModelList when needed (fLastCrossedParticle !=
|
||||
the actual tracked particle);
|
||||
- Changes in the
|
||||
G4FastSimulationManager() (Constructor)
|
||||
ActivateFastSimulationModel(),
|
||||
InActivateFastSimulationModel(),
|
||||
AtRestGetFastSimulationManagerTrigger(),
|
||||
AddFastSimulationModel(),
|
||||
RemoveFastSimulationModel()
|
||||
methodes to set the fLastCrossedParticle to NULL, forcing the
|
||||
fApplicableModelList to be rebuilt.
|
||||
|
||||
September 22, 1998 P.Mora de Freitas
|
||||
Fixed bug in parallel navigation.
|
||||
File touched: G4FastSimulationManagerProcess.cc
|
||||
Tested on HP-aCC.
|
||||
|
||||
September 17, 1998 P.Mora de Freitas
|
||||
G4FastSimulationManager::RemoveFastSimulationModel() updated to look
|
||||
for also in the fInactivatedModels list.
|
||||
|
||||
Tested on HP-aCC.
|
||||
|
||||
September 16, 1998 P.Mora de Freitas
|
||||
New /param/ control commands:
|
||||
|
||||
/param/ActivateModel <ModelName>
|
||||
/param/InActivateModel <ModelName>
|
||||
|
||||
Activate or inactivate a given parameterisation model.
|
||||
|
||||
Tested on HP-aCC.
|
||||
|
||||
August 21, 1998 P.Mora de Freitas
|
||||
G4FastSimulationManagerProcess's G4ProcessType set to
|
||||
fParameterisation, accordingly with procman-00-02-03.
|
||||
|
||||
Tested on HP-aCC.
|
||||
|
||||
August 12, 1998 P.Mora de Freitas
|
||||
Improved the "close parameterisation control" to
|
||||
|
||||
1) avoid the close looping when unnecessary (mostly cases);
|
||||
2) force re-close when necessary (insert/remove ghosts).
|
||||
|
||||
Changes:
|
||||
|
||||
1) the G4GlobalFastSimulationManager::fClosed is now initialised
|
||||
to true by the G4GlobalFastSimulationManager constructor;
|
||||
|
||||
2) new method
|
||||
|
||||
void
|
||||
G4GlobalFastSimulationManager::FastSimulationNeedsToBeClosed();
|
||||
|
||||
called by the AddGhostPlacement and RemoveGhostPlacement
|
||||
G4FastSimulationManager methods to set false the fClosed flag;
|
||||
|
||||
3) changes in the G4GlobalFastSimulationManager::Notify method
|
||||
to deal with these changes.
|
||||
|
||||
Tested on HP-aCC.
|
||||
|
||||
August 11, 1998 P.Mora de Freitas
|
||||
Fix to the G4FastStep::KillPrimaryTrack() method to drop the
|
||||
nonsense line
|
||||
|
||||
SetMomentumChange(0.,0.,0.) ; /* necessary ? */
|
||||
|
||||
Tested on HP-aCC.
|
||||

|
||||
|
||||
|
||||
August 10, 1998 P.Mora de Freitas
|
||||
Fix to the SetPrimaryTrackFinalKineticEnergyAndDirection() method
|
||||
from the G4FastStep class the SetMomentumChange() call to insure that
|
||||
the new momentum direction is a unit vector (as asked by the
|
||||
G4DynamicParticle::SetMomentumDirection method).
|
||||
|
||||
Touched files: G4FastStep.hh (improved comments)
|
||||
G4FastStep.cc (fixed)
|
||||
|
||||
Tested on HP-aCC.
|
||||
