20----------------------------------
21- Retagged - to propose for testing.
22
23November 17th, 2009, J.Apostolakis transport-V09-02-00
24----------------------------------
25- G4Transportation:
26 o Fix: Update the Step flag which identifies the Last Step in a volume
27 It is now done for the linear steps (no charge or no field)
28
29November 26th, 2008, J.Apostolakis transport-V09-01-03
30----------------------------------
31- G4CoupledTransportation:
32 o Fix: initialise new data member (in constructor) - found by STT
33
34November 21st, 2008, J.Apostolakis transport-V09-01-02
35----------------------------------
36- G4Transportation & G4CoupledTransportation:
37 o Performance improvement/correction
38 Avoid to compute safety at end of step for neutral particles
39
40November 21st, 2008, J.Apostolakis transport-V09-01-01
41----------------------------------
42
43- G4Transportation & G4CoupledTransportation:
44 o Push value & origin of safety to SafetyHelper
45 only when its value comes from ComputeSafety
46
47January 17th, 2008, J.Apostolakis transport-V09-01-00
48---------------------------------
49- G4Transportation & G4CoupledTransportation:
50 o Clear state of all Chord Finders using G4FieldManagerStore.
51- Syncronised with files on the HEAD.
52- Requires co-working tag "field-V09-01-00" (or "field-V09-00-03").
53 Functionality corresponding to tag "transport-V09-00-52".
54
55November 27th, 2007, J.Apostolakis transport-V09-00-08
56----------------------------------
57- G4CoupledTransportation
58 o Added updating of particle-looping flag (was commented out.).
59
60November 10th, 2007, J.Apostolakis transport-V09-00-07
61----------------------------------
62- G4Transportation:
63 o Put back the default for short step optimisation to 'on'.
64
65November 9th, 2007, J.Apostolakis transport-V09-00-06
66---------------------------------
67- G4Transportation:
68 o Update the SafetyHelper using the safety calculated by Navigator.
69
70November 27th, 2007, J.Apostolakis transport-V09-00-05a
71----------------------------------
72- G4CoupledTransportation
73 o Added updating of particle-looping flag (was commented out.)
74- Also called "transport-V09-00-51" to make it canonical.
75
76November 8th, 2007, J.Apostolakis transport-V09-00-05
77---------------------------------
78- G4Transportation:
79 o Created new method (and class member) for flag on Short StepOptimisation.
80 * When it is true, the optimisation is 'on' steps shorter than the
81 safety will not call G4Navigator - so long as the particle goes straight
82 ie it is not charged or there is no field.
83 * Retained the default value as 'off' - as since changed in
84 transport-V09-00-02 following Alex's suggestion.
85
86November 8th, 2007, J.Apostolakis transport-V09-00-04
87---------------------------------
88- G4Transportation (AlongStepGPIL):
89 o Moved the call to ConfigureForTrack before the check whether
90 fieldMgr has 0 field ptr, in order to enable it to be called
91 even if the field manager points to a zero field.
92 Needed to enable a user to switch a global field on (off was possible),
93 as a track goes between volume (or regions) of a setup.
94 [ Response to request of Atlas/ZM. ]
95 Note: this ordering already existed in G4CoupledTransportation.
96
97October 12th, 2007, J.Apostolakis transport-V09-00-03
98---------------------------------

101 any geometry (including a parallel geometry) limits the step.
102 New PathFinder method required.
103- Requires and co-works with tag geomnav-V09-00-03

106--------------------------------
107- G4CoupledTransportation:
108 o First fix for problem in condition for Relocating when only a parallel
109 geometry limited the step.
110 o Change of condition for recalculation safety (from Alex Howard) used,
111 as currently it improves stability.
112
113September 25th, 2007, J.Apostolakis transport-V09-00-01
114-----------------------------------
115- G4Transportation:
116 Modification to disable 'optimisation' in G4Navigator for small linear
117 step (ie when a track does less than the safety).
118 * Relevant only if there is no field, or the particle is neutral
119 * Temporary measure (in current form) to improve comparison
120 old / new Transportation (single/old vs coupled with pathfinder).
121

230- G4CoupledTransportation:
231 o Make treatment of mass and full safety coherent (to-dos remain in
232 G4PathFinder).
233 o Added storing of full safety in state; retrieve it after compute step

240
241February 15th, 2007, J.Apostolakis transport-V08-02-00
242----------------------------------
243- G4Transportation: call PropagatorInField to clear state for new track
244 --> addresses reliabilitiy problem seen by Atlas. This fix is related
245 to overlaps, clearing the safety value (which is multivalued due
246 to the overlaps, and thus can become invalid for a new track in
247 an overlap region.)
248
249November 22nd, 2006, J.Apostolakis transport-V08-01-04
250---------------------------------

255---------------------------------
256- G4CoupledTransportation:
257 o AlongStepGPIL() now returns an estimate for the safety for all geometries
258 to make up for the fact that some other processes only have PostStep GPILs
259 which cannot currently influence safety.
260- NOTE: Fix / Workaround for deficiency of others.
261
262November 13th, 2006, J.Apostolakis transport-V08-01-01

275----------------------------------------------
276- Corrected problem with suspended tracks - PR# 802.
277- Added StartTracking() method which takes over responsibility to
278 clear the state for a new track, and to message other relevant
279 component to clear their state (problem report and proposed revision
280 by P.MoraDeFreitas).
281
282Jan. 16th, 2006, J.Apostolakis transport-V08-00-00
283------------------------------
284- G4Transportation:
285 o The particle's charge is now taken from the dynamic particle, so that

492
493Oct 10th, 2002 M.Dressel transport-V04-01-01-internal-5
494--------------------------------------------------------
495- changing sampler concept: instead of separat samplers for
496 all combinations of importance sampling, scoring, wieght roulette
497 for parallel and mass geometry there are two Samplers now
498 for the mass and parallel geometry: G4MassGeometrySampler
499 and G4ParallelGeometrySampler.
500- Introduction of Configurators to setup the processes.
501
502Sep 18th, 2002 M.Dressel transport-V04-01-01-internal-4
503--------------------------------------------------------
504- tagging a version before reducing the number of Samplers

506Sep 2th, 2002 M.dressel transport-V04-01-01-internal-3
507-----------------------------------------
508 code cleanup for code-wizard
509
510Aug 29th, 2002 M.Dressel int-1-V04-01-01
511-----------------------------------------
512- adopted to changes in int-2-geombias-V04-01-01:
513 renaming of G4PTouchableKey to G4GeometryCell
514 changing G4VIStore and G4IStore
515 and dependants
516
517Aug 13th, 2002 M.Dressel transport-V04-01-01
518----------------------------------------------
519- added G4CellStoreScorer, G4VTrackTerminator and changed the sampler
520 classes in order to use the G4VTrackTerminator (if necessary) to
521 kill a track.
522- coworks with geombias-V04-01-01
523
524July 18th, 2002 M.Dressel
525-------------------------

528July 11th, 2002 M.Dressel internal-2-transport-V04-01-01
529--------------------------------------------------------
530- moved the standard scoring classes to run because
531 they need G4EventManager.
532
533July 10th, 2002 M.Dressel internal-1-transport-V04-01-01
534--------------------------------------------------------
535- add classes for standard scoreing. Remove G4ScorePrinter and G4Scorer.
536 G4StandardScorer and G4StandardScoreTable may be used as replacement.
537 The source file G4StandardScorer.cc may be found in
538 extended/examples/B09/src because it needs to acces the
539 G4EventManager.

551- bug fix in G4PArallelScoreSampler.cc and remove Warning from
552 ParallelTransport.
553
554May 31, 2002 M.Dressel transport-V04-00-06
555--------------------------------------------------------
556- renaming of the Manager classes to Sampler classes
557- substitution of G4ParallelManager inside the Sampler classes
558
559May 30, 2002 M.Dressel
560--------------------------------------------------------
561- chamged G4VImportanceScoreConstructor to G4VSampler
562
563May 30, 2002 M.Dressel
564--------------------------------------------------------
565- all the ImportanceScoreManagers derive form
566 G4VImportanceScoreConstructor
567
568May 30, 2002 M.Dressel internal-3-transport-V04-00-05
569--------------------------------------------------------
570- changes in Importance Manager constructors, G4ImportanceAlgorithm as
571 pointer
572
573May 29, 2002 M.Dressel internal-2-transport-V04-00-05
574--------------------------------------------------------
575- bug fix in G4PImportanceWWindowScoreManager.cc
576 and G4ParallelImportanceManager.hh.
577
578May 24, 2002 M.Dressel internal-1-transport-V04-00-05
579-------------------------
580- Change in G4VProcessPlacer and G4ProcessPlacer: add member function
581 RemoveProcess to properly remove a process.
582- Add classes for wieght window biasing.
583
584
585May 02, 2002 M.Dressel
586-------------------------
587- Change in G4ProcessPlacer: set process vector via process manager not
588 directly.
589- Change in G4ParallelTranport: use StartTracking to signal inital step.
590 This should help to locate "suspended" tracks.
591
592April 24, 2002 G.Cosmo - transport-V04-00-05
593-----------------------
594- Added G4DEBUG_TRANSPORT flag in GNUmakefile and (on suggestionh of
595 J.Apostolakis) replaced to G4VERBOSE in G4Transportation::PostStepDoIt()
596 for extra-check on volume boundary.
597 Issues addressed by problem report #130 should now be resolved.
598
599April 10, 2002 M.Dressel - transport-V04-00-04
600-------------------------
601- Added comments to headers of transportation classes and managers for
602 importance biasing, to fullfill Software Reference Manual.
603
604Apr 9, 2002 G.Cosmo
605-------------------
606- Added liability disclaimer to scorer classes and minor cosmetics.
607
608Apr 8, 2002 M.Dressel - transport-V04-00-03
609---------------------

611
612Apr 4, 2002 M.Dressel - transport-V04-00-02
613---------------------
614- Cleaned compilation problems for G4std/std.
615
616Apr 4, 2002 M.Dressel - transport-V04-00-01
617---------------------
618- Resolved compilation problems on SUN-CC and Linux-egcs.
619
620Mar 28, 2002 M.Dressel - transport-V04-00-00
621-----------------------
622- First implementation of transportation classes and managers for importance
623 biasing and scoring. Co-works with "geometry-V04-00-01".
624
625Mar 25, 2002 G.Cosmo
626---------------------
627- Added dependency to new module geometry/biasing in GNUmakefile.
628
629Dec 8, 2001 J.Apostolakis - transport-V03-02-07
630---------------------------
631- Activated the killing of 'looping' particles -- to be used also to
632 abandon (kill) particles that are stuck (eg at boundaries).
633 [ Fix for problems of stuck particles reported by CMS (P.Arce),
634 and Atlas (A.Del'Acqua, A.Rimoldi) ]
635
636Nov 28, 2001 J.Apostolakis - transport-V03-02-06
637---------------------------
638- Fix for the new updating of the time for fields -- correcting previous
639 tag. By keeping account whether the field changes the energy (and
640 therefore the velocity) in the field manager.
641
642 Requires and co-works with
643 - "field-V03-02-07"
644 - "geomvol-V03-02-02"
645 in order to compile (let alone have any effect.)
646
647Nov 10, 2001 J.Apostolakis - transport-V03-02-05
648---------------------------
649- Motivated by the use case of an Electric Field,
650 * in order to achieve reasonable accuracy in time integration,
651 * and to enable fields that vary with the global time
652 changed Transportation to try to obtain the delta_time from FieldTrack.
653 Co-works with and requires "field-V03-02-03" to have any effect.
654
655Nov 9, 2001 G. Cosmo - transport-V03-02-04
656------------------------
657- Fix in G4Transportation.cc for initialisation of touchable handle.
658
659Nov 8, 2001 G. Cosmo - transport-V03-02-03
660------------------------
661- Introduced changes to G4Transportation for reference-counted
662 touchables (R.Chytracek). Added methods GetFreeTouchable() and
663 SetTheOtherTouchableFree(G4VTouchable*).
664
665Nov 6, 2001 J. Apostolakis - transport-V03-02-02
666------------------------------
667- Added protection in G4Transportation::AlongStepGPIL for messaging
668 "ResestStepEstimate" of ChordFinder for the case there is no global field.
669 ** NOTE this is not a perfect resolution (see NOTE in log file). **
670 --> Thanks to Radovan Chytracek for reporting this problem (move to file log)
671
672Aug 16, 2001 J. Apostolakis - transport-V03-02-01
673------------------------------
674- Tagged. (This tag requires field-V03-02-00)
675
676Aug 16, 2001 J. Apostolakis
677------------------------------
678- Erasing state information from previous track at the first step of
679 each track. (-> this is required to ensure repeatability)
680 This should eliminate any non-repeatability due to the propagation
681 in field.
682 ( Requires updated version of G4ChordFinder )
683
684Jul 19, 2001 G. Cosmo transport-V03-02-00
685------------------------
686- Synchronised with CVS HEAD after introduction of warrenty disclaimer.
687- Modified author list in G4Transportation (P.Gumplinger).
688
689Apr 11, 2001 J. Apostolakis transport-V03-01-02
690------------------------------
691- Corrected the last update of G4Transportation.cc, which overwrote the
692 value of the spin in the cases where a particle was not charged (eg photon)
693 or a charged particle was not in a field.
694
695Apr 11, 2001 P. Gumplinger transport-V03-01-01
696-----------------------------
697- Updated G4Transportation.cc to make spin tracking work correctly:
698 o Replaced the line originally commented out:
699 // fTransportEndPolarization= aFieldTrack.GetSpin() ; // Not yet possible
700 with:
701 fTransportEndSpin = aFieldTrack.GetSpin();
702 o Added to the AlongStepDoIt() the following call:
703 fParticleChange.SetPolarizationChange(fTransportEndSpin);
704
705Mar 19, 2001 J. Apostolakis transport-V03-00-01
706------------------------------
707- G4Transportation modified to use new FieldTrack, and get Kinetic
708 Energy from it.
709 This new FieldTrack together with changes in associated Equation of Motion
710 classes implement the momentum vector as independent variable in place of
711 the velocity.
712 So this tag requires
713 - new geometry/magneticfield tag "field-V03-00-01", and
714 - new geometry/volumes tag "geomvol-V03-00-03" for new
715 G4PropagatorInField ().
716
717Feb 27, 2001 J. Apostolakis (transport-V03-00-00)
718------------------------------
719- G4Transportation.cc:
720 * Modified calculation of energy at the end of field step
721 to make it more accurate at low velocities,
722 (while remaining correct at high gammas).
723 This improves the energy determination.
724 Together with electromagnetic/standard tag "stand-V03-00-03"
725 this addresses the main problem in propagating in an electric field
726 (Problem report # 108 )
727
728Sep 22, 2000 V. Grichine (transport-V02-00-00) [recorded by G.Cosmo]
729---------------------------
730- G4Transportation.cc:
731 o added formula for Tkin corresponding directly to
732 relativistic definition of Tkin = Etot - mc^2 = mc^2(gamma -1),
733 where gamma is a particle Lorentz factor.
734 o general cosmetics.
735
736Jun 19, 2000 J. Apostolakis (transport-V01-01-02)
737------------------------------
738- G4Transportation.cc: Set the True Step Length in G4Transportation.cc
739- Cosmetic: updated other files to the head, as there were no differences
740 from it (CVS headers).
741
742May 15, 2000 J. Apostolakis (transport-V01-01-01)
743------------------------------
744- G4Transportation.cc: Set the material in materialChange, in order to get
745 correct behaviour for volumes that parameterise the material.
746 (Fix is dependant on changes to particleChangeForTransport and StepPoint)
747- Modified setting of touchable change, in order to preserve const-ness where
748 it exists.
749
750Nov 25, 1999 J. Apostolakis (transport-V00-01-01)
751------------------------------
752- G4Transportation.cc: Added protection for the case of a zero step (when
753 there is a field)
754- G4UserSpecialCuts: protection to use min range and min kinE only for
755 charged particles.
756
757June 9, 1999 J. Apostolakis (transport-01-00-02)
758------------------------------
759- Added a protection so that full relocation is not used for very small moves.
760
761Dec 4, 1998 J. Apostolakis (transport-00-04-01)
762------------------------------
763- The Velocity Vector for Transport in a magnetic field is now set correctly.
764 (previously the scalar velocity was automatically promoted to a 3-vector)
765
766Nov 25, 1998 J. Apostolakis
767-----------------------------
768- Added the direction to LocateGlobalPointAndUpdateTouchable.
769
770Nov 19, 1998 J. Apostolakis (transport-00-03-04)
771------------------------------
772- Fixes:
773 1) The final energy is set equal to the initial energy, because
774 the PropagatorInField does not calculate it correctly yet. NEEDS Fix
775 2) If the requested step size is zero and safety is zero, the
776 step is now considered geometry limited. (This can happen
777 if a discrete process tries to take a step that is very small
778 compared to the mean free path.) Problem observed by Laszlo in EM tests.
779 3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity.
780
781Nov 11, 1998 J. Apostolakis (transport-00-03-03)
782------------------------------
783- Changes to accomodate new interface of Field:
784 G4PropagatorInField and G4FieldTrack.
785
786Oct 30, 1998 J. Apostolakis (transport-00-03-02)
787-----------------------------
788- In the case of magnetic field, a flag that determines whether the
789 geometry limited the step was not set.
790
791Sep 16, 1998 J. Apostolakis (transport-00-03-01)
792-----------------------------
793- Checks whether the particle is out of the world volume,
794 if so it has exited and must be killed.
795
796Aug 28, 1998 J. Apostolakis
797-----------------------------
798- The PostStepGetPhysicalInteractionLength has fixed (to return kInf)
799 The boolean flags for touchables are now initialised. & Other small fixes ?
800 Test code for non-relocating case added (for debugging).
801
802June 08, 1998 J. Apostolakis (trans-06-04)
803------------------------------
804- Corrected Safety computation for the case of the field (adding endpoint
805 distance instead of curve length.)
806- Added PostStepDoIt method that tries to relocate the particle using
807 G4ParticleChangeForTransport
808- Transportation is no longer a G4ContinuousProcess.
809
810June 08, 1998 J. Apostolakis (trans-06-03)
811------------------------------
812- Modified it to recomputate Safety at the start of a step. To do this
813 it uses the previous step's calculated safety and endpoint.
814
815June 08, 1998 J. Apostolakis (trans-06-02)
816------------------------------
817- Modified it to add re-computation of Safety at the endpoint of a step,
818 when the safety would become negative. This is done to allow processes
819 to benefit from a realistic (geometrical) value of the safety. The
820 request to do this was from EM physics
821
822June 03, 1998 J. Apostolakis (trans-06-01)
823------------------------------
824- The safety we is now generalised to mean the limit of assumption of all
825 processes. The AlongStepGPIL input value is not the remainder from the
826 previous step's geometrical safety.
827 So the transportation must recalculate the starting point's safety here.
828 As a zeroeth order approximation we set it to zero.
829
830April 17, 1998 M. Maire [recorded by John Apostolakis]
831------------------------
832- A new process, G4UserSpecialCuts, was added to allow the
833 user an alternative method to set some user cuts.
834
835April 15, 1998 H. Kurasige [recorded by John Apostolakis]
836---------------------------
837- The transportation does the absolute minimum required to conform to
838 the new scheme for ParticleChange: G4VParticleChange is used in signature.
839 [ But default G4ParticleChange is still used ].
