Sep 18th, 2002 M.Dressel transport-V04-01-01-internal-4 -------------------------------------------------------- - tagging a version before reducing the number of Samplers Sep 2th, 2002 M.dressel transport-V04-01-01-internal-3 ----------------------------------------- code cleanup for code-wizard Aug 29th, 2002 M.Dressel int-1-V04-01-01 ----------------------------------------- - adopted to changes in int-2-geombias-V04-01-01: renaming of G4PTouchableKey to G4GeometryCell changing G4VIStore and G4IStore and dependants Aug 13th, 2002 M.Dressel transport-V04-01-01 ---------------------------------------------- - added G4CellStoreScorer, G4VTrackTerminator and changed the sampler classes in order to use the G4VTrackTerminator (if necessary) to kill a track. - coworks with geombias-V04-01-01 July 18th, 2002 M.Dressel ------------------------- - bug fix in G4TrackLogger July 11th, 2002 M.Dressel internal-2-transport-V04-01-01 -------------------------------------------------------- - moved the standard scoring classes to run because they need G4EventManager. July 10th, 2002 M.Dressel internal-1-transport-V04-01-01 -------------------------------------------------------- - add classes for standard scoreing. Remove G4ScorePrinter and G4Scorer. G4StandardScorer and G4StandardScoreTable may be used as replacement. The source file G4StandardScorer.cc may be found in extended/examples/B09/src because it needs to acces the G4EventManager. Jun 13, 2002 M.Dressel transport-V04-00-09 --------------------------------------------- - add classes for creating and printing tallies. May 31, 2002 M.Dressel transport-V04-00-08 -------------------------------------------------------- - made weight window sampling to apply only at inital track step 1. May 31, 2002 M.Dressel transport-V04-00-07 -------------------------------------------------------- - bug fix in G4PArallelScoreSampler.cc and remove Warning from ParallelTransport May 31, 2002 M.Dressel transport-V04-00-06 -------------------------------------------------------- - renaming of the Manager classes to Sampler classes - substitution of G4ParallelManager inside the Sampler classes May 30, 2002 M.Dressel -------------------------------------------------------- - chamged G4VImportanceScoreConstructor to G4VSampler May 30, 2002 M.Dressel -------------------------------------------------------- - all the ImportanceScoreManagers derive form G4VImportanceScoreConstructor May 30, 2002 M.Dressel internal-3-transport-V04-00-05 -------------------------------------------------------- - changes in Importance Manager constructors, G4ImportanceAlgorithm as pointer May 29, 2002 M.Dressel internal-2-transport-V04-00-05 -------------------------------------------------------- - bug fix in G4PImportanceWWindowScoreManager.cc and G4ParallelImportanceManager.hh. May 24, 2002 M.Dressel internal-1-transport-V04-00-05 ------------------------- - Change in G4VProcessPlacer and G4ProcessPlacer: add member function RemoveProcess to properly remove a process. - Add classes for wieght window biasing. May 02, 2002 M.Dressel ------------------------- - Change in G4ProcessPlacer: set process vector via process manager not directly. - Change in G4ParallelTranport: use StartTracking to signal inital step. This should help to locate "suspended" tracks. April 24, 2002 G.Cosmo - transport-V04-00-05 ----------------------- - Added G4DEBUG_TRANSPORT flag in GNUmakefile and (on suggestionh of J.Apostolakis) replaced to G4VERBOSE in G4Transportation::PostStepDoIt() for extra-check on volume boundary. Issues addressed by problem report #130 should now be resolved. April 10, 2002 M.Dressel - transport-V04-00-04 ------------------------- - Added comments to headers of transportation classes and managers for importance biasing, to fullfill Software Reference Manual. Apr 9, 2002 G.Cosmo ------------------- - Added liability disclaimer to scorer classes and minor cosmetics. Apr 8, 2002 M.Dressel - transport-V04-00-03 --------------------- - Resolved compilation problems on HP-aCC. Apr 4, 2002 M.Dressel - transport-V04-00-02 --------------------- - Cleaned compilation problems for G4std/std. Apr 4, 2002 M.Dressel - transport-V04-00-01 --------------------- - Resolved compilation problems on SUN-CC and Linux-egcs. Mar 28, 2002 M.Dressel - transport-V04-00-00 ----------------------- - First implementation of transportation classes and managers for importance biasing and scoring. Co-works with "geometry-V04-00-01". Mar 25, 2002 G.Cosmo --------------------- - Added dependency to new module geometry/biasing in GNUmakefile. Dec 8, 2001 J.Apostolakis - transport-V03-02-07 --------------------------- - Activated the killing of 'looping' particles -- to be used also to abandon (kill) particles that are stuck (eg at boundaries). [ Fix for problems of stuck particles reported by CMS (P.Arce), and Atlas (A.Del'Acqua, A.Rimoldi) ] Nov 28, 2001 J.Apostolakis - transport-V03-02-06 --------------------------- - Fix for the new updating of the time for fields -- correcting previous tag. By keeping account whether the field changes the energy (and therefore the velocity) in the field manager. Requires and co-works with - "field-V03-02-07" - "geomvol-V03-02-02" in order to compile (let alone have any effect.) Nov 10, 2001 J.Apostolakis - transport-V03-02-05 --------------------------- - Motivated by the use case of an Electric Field, * in order to achieve reasonable accuracy in time integration, * and to enable fields that vary with the global time changed Transportation to try to obtain the delta_time from FieldTrack. Co-works with and requires "field-V03-02-03" to have any effect. Nov 9, 2001 G. Cosmo - transport-V03-02-04 ------------------------ - Fix in G4Transportation.cc for initialisation of touchable handle. Nov 8, 2001 G. Cosmo - transport-V03-02-03 ------------------------ - Introduced changes to G4Transportation for reference-counted touchables (R.Chytracek). Added methods GetFreeTouchable() and SetTheOtherTouchableFree(G4VTouchable*). Nov 6, 2001 J. Apostolakis - transport-V03-02-02 ------------------------------ - Added protection in G4Transportation::AlongStepGPIL for messaging "ResestStepEstimate" of ChordFinder for the case there is no global field. ** NOTE this is not a perfect resolution (see NOTE in log file). ** --> Thanks to Radovan Chytracek for reporting this problem (move to file log) Aug 16, 2001 J. Apostolakis - transport-V03-02-01 ------------------------------ - Tagged. (This tag requires field-V03-02-00) Aug 16, 2001 J. Apostolakis ------------------------------ - Erasing state information from previous track at the first step of each track. (-> this is required to ensure repeatability) This should eliminate any non-repeatability due to the propagation in field. ( Requires updated version of G4ChordFinder ) Jul 19, 2001 G. Cosmo transport-V03-02-00 ------------------------ - Synchronised with CVS HEAD after introduction of warrenty disclaimer. - Modified author list in G4Transportation (P.Gumplinger). Apr 11, 2001 J. Apostolakis transport-V03-01-02 ------------------------------ - Corrected the last update of G4Transportation.cc, which overwrote the value of the spin in the cases where a particle was not charged (eg photon) or a charged particle was not in a field. Apr 11, 2001 P. Gumplinger transport-V03-01-01 ----------------------------- - Updated G4Transportation.cc to make spin tracking work correctly: o Replaced the line originally commented out: // fTransportEndPolarization= aFieldTrack.GetSpin() ; // Not yet possible with: fTransportEndSpin = aFieldTrack.GetSpin(); o Added to the AlongStepDoIt() the following call: fParticleChange.SetPolarizationChange(fTransportEndSpin); Mar 19, 2001 J. Apostolakis transport-V03-00-01 ------------------------------ - G4Transportation modified to use new FieldTrack, and get Kinetic Energy from it. This new FieldTrack together with changes in associated Equation of Motion classes implement the momentum vector as independent variable in place of the velocity. So this tag requires - new geometry/magneticfield tag "field-V03-00-01", and - new geometry/volumes tag "geomvol-V03-00-03" for new G4PropagatorInField (). Feb 27, 2001 J. Apostolakis (transport-V03-00-00) ------------------------------ - G4Transportation.cc: * Modified calculation of energy at the end of field step to make it more accurate at low velocities, (while remaining correct at high gammas). This improves the energy determination. Together with electromagnetic/standard tag "stand-V03-00-03" this addresses the main problem in propagating in an electric field (Problem report # 108 ) Sep 22, 2000 V. Grichine (transport-V02-00-00) [recorded by G.Cosmo] --------------------------- - G4Transportation.cc: o added formula for Tkin corresponding directly to relativistic definition of Tkin = Etot - mc^2 = mc^2(gamma -1), where gamma is a particle Lorentz factor. o general cosmetics. Jun 19, 2000 J. Apostolakis (transport-V01-01-02) ------------------------------ - G4Transportation.cc: Set the True Step Length in G4Transportation.cc - Cosmetic: updated other files to the head, as there were no differences from it (CVS headers). May 15, 2000 J. Apostolakis (transport-V01-01-01) ------------------------------ - G4Transportation.cc: Set the material in materialChange, in order to get correct behaviour for volumes that parameterise the material. (Fix is dependant on changes to particleChangeForTransport and StepPoint) - Modified setting of touchable change, in order to preserve const-ness where it exists. Nov 25, 1999 J. Apostolakis (transport-V00-01-01) ------------------------------ - G4Transportation.cc: Added protection for the case of a zero step (when there is a field) - G4UserSpecialCuts: protection to use min range and min kinE only for charged particles. June 9, 1999 J. Apostolakis (transport-01-00-02) ------------------------------ - Added a protection so that full relocation is not used for very small moves. Dec 4, 1998 J. Apostolakis (transport-00-04-01) ------------------------------ - The Velocity Vector for Transport in a magnetic field is now set correctly. (previously the scalar velocity was automatically promoted to a 3-vector) Nov 25, 1998 J. Apostolakis ----------------------------- - Added the direction to LocateGlobalPointAndUpdateTouchable. Nov 19, 1998 J. Apostolakis (transport-00-03-04) ------------------------------ - Fixes: 1) The final energy is set equal to the initial energy, because the PropagatorInField does not calculate it correctly yet. NEEDS Fix 2) If the requested step size is zero and safety is zero, the step is now considered geometry limited. (This can happen if a discrete process tries to take a step that is very small compared to the mean free path.) Problem observed by Laszlo in EM tests. 3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity. Nov 11, 1998 J. Apostolakis (transport-00-03-03) ------------------------------ - Changes to accomodate new interface of Field: G4PropagatorInField and G4FieldTrack. Oct 30, 1998 J. Apostolakis (transport-00-03-02) ----------------------------- - In the case of magnetic field, a flag that determines whether the geometry limited the step was not set. Sep 16, 1998 J. Apostolakis (transport-00-03-01) ----------------------------- - Checks whether the particle is out of the world volume, if so it has exited and must be killed. Aug 28, 1998 J. Apostolakis ----------------------------- - The PostStepGetPhysicalInteractionLength has fixed (to return kInf) The boolean flags for touchables are now initialised. & Other small fixes ? Test code for non-relocating case added (for debugging). June 08, 1998 J. Apostolakis (trans-06-04) ------------------------------ - Corrected Safety computation for the case of the field (adding endpoint distance instead of curve length.) - Added PostStepDoIt method that tries to relocate the particle using G4ParticleChangeForTransport - Transportation is no longer a G4ContinuousProcess. June 08, 1998 J. Apostolakis (trans-06-03) ------------------------------ - Modified it to recomputate Safety at the start of a step. To do this it uses the previous step's calculated safety and endpoint. June 08, 1998 J. Apostolakis (trans-06-02) ------------------------------ - Modified it to add re-computation of Safety at the endpoint of a step, when the safety would become negative. This is done to allow processes to benefit from a realistic (geometrical) value of the safety. The request to do this was from EM physics June 03, 1998 J. Apostolakis (trans-06-01) ------------------------------ - The safety we is now generalised to mean the limit of assumption of all processes. The AlongStepGPIL input value is not the remainder from the previous step's geometrical safety. So the transportation must recalculate the starting point's safety here. As a zeroeth order approximation we set it to zero. April 17, 1998 M. Maire [recorded by John Apostolakis] ------------------------ - A new process, G4UserSpecialCuts, was added to allow the user an alternative method to set some user cuts. April 15, 1998 H. Kurasige [recorded by John Apostolakis] --------------------------- - The transportation does the absolute minimum required to conform to the new scheme for ParticleChange: G4VParticleChange is used in signature. [ But default G4ParticleChange is still used ]. April 14, 1998 John Apostolakis -------------------------------- - History file Created
