1 # Category transport History 2 3 See `CONTRIBUTING.rst` for details of **required** info/format for each entry, 4 which **must** added in reverse chronological order (newest at the top). 5 It must **not** be used as a substitute for writing good git commit messages! 6 7 ------------------------------------------------------------------------------- 8 9 ## 2024-10-08 Jonas Hahnfeld (transport-V11-02-00) 10 - Introduce `TRANSPORTATION_WITH_MSC` process sub type 11 12 ## 2023-01-26 John Apostolakis (transport-V11-01-02) 13 - Added a method to set both warning & important energies in G4TransporationParameters 14 Added method to report lock errors. 15 Improve reporting of inconsistent changes of 'warning' & 'important' energies 16 (not only enforce warning_E < important_E but also warn about violations.) 17 18 ## 2023-01-25 John Apostolakis (transport-V11-01-01) 19 - Fix unwanted change of default looper parameters. 20 ( Reversed inadvertent creation of G4TransportationParameters in 21 calls to G4Transportation constructor.) 22 23 ## 2023-01-09 Jonas Hahnfeld (transport-V11-01-00) 24 - Fix compilation warning about unused variable without `G4VERBOSE`. 25 26 ## 2022-11-25 Gabriele Cosmo (transport-V11-00-10) 27 - Removed debug printouts in G4Transportation. 28 29 ## 2022-11-23 Gabriele Cosmo (transport-V11-00-09) 30 - Fixed compilation warnings for implicit type conversions on macOS/XCode 14.1. 31 32 ## 2022-11-10 John Apostolakis (transport-V11-00-08) 33 - New class G4TransporationParameters to hold looper parameters & others. 34 This is a class to be created in master and hold the values of all looper 35 parameters for G4Transportation and derived classes. 36 * G4Transporation's constructor checks for the existence of a default 37 instance. If found, its values will be assigned to the corresponding 38 data members of G4Transporation. 39 This behaviour is inherited by subclasses (using this constructor). 40 * The (default) 'instance' of G4TransportationParameters should be 41 shared by all threads, and used for all particle types. 42 These values could be subsequently changed - e.g. in User Actions. 43 * The G4TransporationParameters object (instance) is current unique. 44 ( Future extensions are envisioned that allow an object of this 45 to be associated with a separate instance of G4Transportation assigned 46 to one or more particle types, e.g. electrons, or muons and positrons. ) 47 48 ## 2022-10-05 Gabriele Cosmo (transport-V11-00-07) 49 - Fixed compilation warnings on Intel/icx compiler for variables set 50 but not used. 51 52 ## 2022-05-18 Gabriele Cosmo (transport-V11-00-06) 53 - `G4Transportation`, `G4CoupledTransportation`: fixed misuse of bitwise '|' 54 operator instead of logical. 55 56 ## 2022-05-11 Jonas Hahnfeld (transport-V11-00-05) 57 - `G4Transportation`: Remove non-working check for any field 58 - Remove `PUBLIC` dependency on `G4magneticfield`, `G4navigation` 59 60 ## 2022-04-24 Vladimir Ivanchenko (transport-V11-00-04) 61 - moved G4UserSpecialCuts to physics_lists/constructors/limiters 62 - GNUmakefile, source.cmake - removed dependence on electromagnetic/utils 63 64 ## 2022-04-20 Jonas Hahnfeld (transport-V11-00-03) 65 - `G4CoupledTransportation`: Set flags from `G4Transportation` 66 * Replace `fFirstStepInAnyVolume` with `fFirstStepInVolume` 67 * Replace `fAnyGeometryLimitedStep` with `fGeometryLimitedStep` 68 * Remove wrong check in case of zero steps 69 - `G4Transportation`: 70 * Remove wrong check in case of zero steps 71 * Set step status on volume boundary 72 73 ## 2022-01-17 Jonas Hahnfeld (transport-V11-00-02) 74 - Remove useless `const_cast` of `G4VSensitiveDetector` 75 76 ## 2022-01-05 Jonas Hahnfeld (transport-V11-00-01) 77 - `G4CoupledTransportation`: 78 * Use new constant `G4TransportationManager::kMassNavigatorId` 79 * Inherit from `G4Transportation`, remove duplicated variables and methods 80 81 ## 2021-12-10 Ben Morgan (transport-V11-00-00) 82 - Change to new Markdown History format 83 84 --- 85 86 # History entries prior to 11.0 87 88 Sep 23rd 2021, Alberto Ribon transport-V10-07-03 89 ---------------------------- 90 - Added PARALLEL_WORLD_PROCESS to G4TransportationProcessType 91 (to avoid hardwired value "491" in the constructor of class 92 G4ParallelWorldProcess). 93 94 Apr 16th 2021, Ben Morgan transport-V10-07-02 95 ------------------------- 96 - Migrate build to modular CMake API 97 98 Feb 24th 2021, G. Cosmo transport-V10-07-01 99 ----------------------- 100 - Enable setting of smooth curved trajectories to particle-change in 101 G4CoupledTransportation::AlongStepDoIt(), which was commented out by 102 mistake. Based on discussion in Geant4 Forum thread #4271. 103 104 Dec 16th 2020, G. Amadio transport-V10-07-00 105 ------------------------ 106 - Limit reporting of number of calls to G4Transportation::AlongStepDoIt() 107 to when either G4VERBOSE or G4DEBUG_TRANSPORT is defined, which allows to 108 avoid using a thread local variable for a slight performance gain. 109 110 Oct 26th 2020, G. Amadio & J.Apostolakis transport-V10-06-00 111 ---------------------------------------- 112 - A substantial reorganisation of G4Transportation::AlongStepGPIL 113 to use values already in cache, reduce the number of branches, and 114 use extra local variables for track properties to avoid indirections. 115 The method is one of the heaviest in many types of simulation workloads. 116 Profiling identified a persistent reduction in misses of instruction-TLB 117 loads after these changes. 118 119 Nov 1st 2019, J.Apostolakis transport-V10-05-02 120 ---------------------------- 121 - Optimisation in G4Transportation and G4CoupledTransportation: 122 Avoid calling user field manager's ConfigureForTrack method, 123 except if particle is charged, or forces from magnetic moment 124 or gravity are enabled. 125 126 * Introduces new common 'flag' in G4(Coupled)Transportation 127 to enable gravity fields. 128 The following static method must be called if the application uses 129 gravity fields: 130 G4Transportation::EnableGravity(G4bool useGravity) 131 132 - Added flag in G4Transportation/G4CoupledTransportation to 133 silence warning about looping tracks. 134 135 Aug 15th 2019, D.Sorokin transport-V10-05-01 136 ------------------------ 137 - Enable relaxing of delta chord condition (to reduce looping particle 138 issue) for tracks below 'important' energy threshold. 139 140 Aug 15th 2019, J.Apostolakis transport-V10-05-00 141 ---------------------------- 142 - G4Transportation and G4CoupledTransportation: fix issues related to 143 resetting of looper flag and other state for field propagation. 144 * Replaced check for 'Global' field with check for any field. 145 This is needed to ensure that propagator-in-field state is 146 reset when the setup inludes only local fields. 147 * Ensure that looping flag is reset (false) when a force is not exerted 148 in G4CoupledTransportation::AlongStepGetPhysicalInteractionLength 149 ( Before it was overwritten afterwards. ) 150 151 Addresses bugzilla Problem report 2144. 152 Thanks to Richard T.

Remove G4ScorePrinter and G4Scorer. 1045 G4StandardScorer and G4StandardScoreTable may be used as replacement. 1046 The source file G4StandardScorer.cc may be found in 1047 extended/examples/B09/src because it needs to acces the 1048 G4EventManager. 1049 1050 Jun 13, 2002 M.Dressel transport-V04-00-09 1051 --------------------------------------------- 1052 - add classes for creating and printing tallies. 1053 1054 May 31, 2002 M.Dressel transport-V04-00-08 1055 -------------------------------------------------------- 1056 - made weight window sampling to apply only at inital track step 1. 1057 1058 May 31, 2002 M.Dressel transport-V04-00-07 1059 -------------------------------------------------------- 1060 - bug fix in G4PArallelScoreSampler.cc and remove Warning from 1061 ParallelTransport. 1062 1063 May 31, 2002 M.Dressel transport-V04-00-06 1064 -------------------------------------------------------- 1065 - renaming of the Manager classes to Sampler classes 1066 - substitution of G4ParallelManager inside the Sampler classes 1067 1068 May 30, 2002 M.Dressel 1069 -------------------------------------------------------- 1070 - chamged G4VImportanceScoreConstructor to G4VSampler 1071 1072 May 30, 2002 M.Dressel 1073 -------------------------------------------------------- 1074 - all the ImportanceScoreManagers derive form 1075 G4VImportanceScoreConstructor 1076 1077 May 30, 2002 M.Dressel internal-3-transport-V04-00-05 1078 -------------------------------------------------------- 1079 - changes in Importance Manager constructors, G4ImportanceAlgorithm as 1080 pointer 1081 1082 May 29, 2002 M.Dressel internal-2-transport-V04-00-05 1083 -------------------------------------------------------- 1084 - bug fix in G4PImportanceWWindowScoreManager.cc 1085 and G4ParallelImportanceManager.hh. 1086 1087 May 24, 2002 M.Dressel internal-1-transport-V04-00-05 1088 ------------------------- 1089 - Change in G4VProcessPlacer and G4ProcessPlacer: add member function 1090 RemoveProcess to properly remove a process. 1091 - Add classes for wieght window biasing. 1092 1093 1094 May 02, 2002 M.Dressel 1095 ------------------------- 1096 - Change in G4ProcessPlacer: set process vector via process manager not 1097 directly. 1098 - Change in G4ParallelTranport: use StartTracking to signal inital step. 1099 This should help to locate "suspended" tracks. 1100 1101 April 24, 2002 G.Cosmo - transport-V04-00-05 1102 ----------------------- 1103 - Added G4DEBUG_TRANSPORT flag in GNUmakefile and (on suggestionh of 1104 J.Apostolakis) replaced to G4VERBOSE in G4Transportation::PostStepDoIt() 1105 for extra-check on volume boundary. 1106 Issues addressed by problem report #130 should now be resolved. 1107 1108 April 10, 2002 M.Dressel - transport-V04-00-04 1109 ------------------------- 1110 - Added comments to headers of transportation classes and managers for 1111 importance biasing, to fullfill Software Reference Manual. 1112 1113 Apr 9, 2002 G.Cosmo 1114 ------------------- 1115 - Added liability disclaimer to scorer classes and minor cosmetics. 1116 1117 Apr 8, 2002 M.Dressel - transport-V04-00-03 1118 --------------------- 1119 - Resolved compilation problems on HP-aCC. 1120 1121 Apr 4, 2002 M.Dressel - transport-V04-00-02 1122 --------------------- 1123 - Cleaned compilation problems for G4std/std. 1124 1125 Apr 4, 2002 M.Dressel - transport-V04-00-01 1126 --------------------- 1127 - Resolved compilation problems on SUN-CC and Linux-egcs. 1128 1129 Mar 28, 2002 M.Dressel - transport-V04-00-00 1130 ----------------------- 1131 - First implementation of transportation classes and managers for importance 1132 biasing and scoring. Co-works with "geometry-V04-00-01". 1133 1134 Mar 25, 2002 G.Cosmo 1135 --------------------- 1136 - Added dependency to new module geometry/biasing in GNUmakefile. 1137 1138 Dec 8, 2001 J.Apostolakis - transport-V03-02-07 1139 --------------------------- 1140 - Activated the killing of 'looping' particles -- to be used also to 1141 abandon (kill) particles that are stuck (eg at boundaries). 1142 [ Fix for problems of stuck particles reported by CMS (P.Arce), 1143 and Atlas (A.Del'Acqua, A.Rimoldi) ] 1144 1145 Nov 28, 2001 J.Apostolakis - transport-V03-02-06 1146 --------------------------- 1147 - Fix for the new updating of the time for fields -- correcting previous 1148 tag. By keeping account whether the field changes the energy (and 1149 therefore the velocity) in the field manager. 1150 1151 Requires and co-works with 1152 - "field-V03-02-07" 1153 - "geomvol-V03-02-02" 1154 in order to compile (let alone have any effect.) 1155 1156 Nov 10, 2001 J.Apostolakis - transport-V03-02-05 1157 --------------------------- 1158 - Motivated by the use case of an Electric Field, 1159 * in order to achieve reasonable accuracy in time integration, 1160 * and to enable fields that vary with the global time 1161 changed Transportation to try to obtain the delta_time from FieldTrack. 1162 Co-works with and requires "field-V03-02-03" to have any effect. 1163 1164 Nov 9, 2001 G. Cosmo - transport-V03-02-04 1165 ------------------------ 1166 - Fix in G4Transportation.cc for initialisation of touchable handle. 1167 1168 Nov 8, 2001 G. Cosmo - transport-V03-02-03 1169 ------------------------ 1170 - Introduced changes to G4Transportation for reference-counted 1171 touchables (R.Chytracek). Added methods GetFreeTouchable() and 1172 SetTheOtherTouchableFree(G4VTouchable*). 1173 1174 Nov 6, 2001 J. Apostolakis - transport-V03-02-02 1175 ------------------------------ 1176 - Added protection in G4Transportation::AlongStepGPIL for messaging 1177 "ResestStepEstimate" of ChordFinder for the case there is no global field. 1178 ** NOTE this is not a perfect resolution (see NOTE in log file). ** 1179 --> Thanks to Radovan Chytracek for reporting this problem (move to file log) 1180 1181 Aug 16, 2001 J. Apostolakis - transport-V03-02-01 1182 ------------------------------ 1183 - Tagged. (This tag requires field-V03-02-00) 1184 1185 Aug 16, 2001 J. Apostolakis 1186 ------------------------------ 1187 - Erasing state information from previous track at the first step of 1188 each track. (-> this is required to ensure repeatability) 1189 This should eliminate any non-repeatability due to the propagation 1190 in field. 1191 ( Requires updated version of G4ChordFinder ) 1192 1193 Jul 19, 2001 G. Cosmo transport-V03-02-00 1194 ------------------------ 1195 - Synchronised with CVS HEAD after introduction of warrenty disclaimer. 1196 - Modified author list in G4Transportation (P.Gumplinger). 1197 1198 Apr 11, 2001 J. Apostolakis transport-V03-01-02 1199 ------------------------------ 1200 - Corrected the last update of G4Transportation.cc, which overwrote the 1201 value of the spin in the cases where a particle was not charged (eg photon) 1202 or a charged particle was not in a field. 1203 1204 Apr 11, 2001 P. Gumplinger transport-V03-01-01 1205 ----------------------------- 1206 - Updated G4Transportation.cc to make spin tracking work correctly: 1207 o Replaced the line originally commented out: 1208 // fTransportEndPolarization= aFieldTrack.GetSpin() ; // Not yet possible 1209 with: 1210 fTransportEndSpin = aFieldTrack.GetSpin(); 1211 o Added to the AlongStepDoIt() the following call: 1212 fParticleChange.SetPolarizationChange(fTransportEndSpin); 1213 1214 Mar 19, 2001 J. Apostolakis transport-V03-00-01 1215 ------------------------------ 1216 - G4Transportation modified to use new FieldTrack, and get Kinetic 1217 Energy from it. 1218 This new FieldTrack together with changes in associated Equation of Motion 1219 classes implement the momentum vector as independent variable in place of 1220 the velocity. 1221 So this tag requires 1222 - new geometry/magneticfield tag "field-V03-00-01", and 1223 - new geometry/volumes tag "geomvol-V03-00-03" for new 1224 G4PropagatorInField (). 1225 1226 Feb 27, 2001 J. Apostolakis (transport-V03-00-00) 1227 ------------------------------ 1228 - G4Transportation.cc: 1229 * Modified calculation of energy at the end of field step 1230 to make it more accurate at low velocities, 1231 (while remaining correct at high gammas). 1232 This improves the energy determination. 1233 Together with electromagnetic/standard tag "stand-V03-00-03" 1234 this addresses the main problem in propagating in an electric field 1235 (Problem report # 108 ) 1236 1237 Sep 22, 2000 V. Grichine (transport-V02-00-00) [recorded by G.Cosmo] 1238 --------------------------- 1239 - G4Transportation.cc: 1240 o added formula for Tkin corresponding directly to 1241 relativistic definition of Tkin = Etot - mc^2 = mc^2(gamma -1), 1242 where gamma is a particle Lorentz factor. 1243 o general cosmetics. 1244 1245 Jun 19, 2000 J. Apostolakis (transport-V01-01-02) 1246 ------------------------------ 1247 - G4Transportation.cc: Set the True Step Length in G4Transportation.cc 1248 - Cosmetic: updated other files to the head, as there were no differences 1249 from it (CVS headers). 1250 1251 May 15, 2000 J. Apostolakis (transport-V01-01-01) 1252 ------------------------------ 1253 - G4Transportation.cc: Set the material in materialChange, in order to get 1254 correct behaviour for volumes that parameterise the material. 1255 (Fix is dependant on changes to particleChangeForTransport and StepPoint) 1256 - Modified setting of touchable change, in order to preserve const-ness where 1257 it exists. 1258 1259 Nov 25, 1999 J. Apostolakis (transport-V00-01-01) 1260 ------------------------------ 1261 - G4Transportation.cc: Added protection for the case of a zero step (when 1262 there is a field) 1263 - G4UserSpecialCuts: protection to use min range and min kinE only for 1264 charged particles. 1265 1266 June 9, 1999 J. Apostolakis (transport-01-00-02) 1267 ------------------------------ 1268 - Added a protection so that full relocation is not used for very small moves. 1269 1270 Dec 4, 1998 J. Apostolakis (transport-00-04-01) 1271 ------------------------------ 1272 - The Velocity Vector for Transport in a magnetic field is now set correctly. 1273 (previously the scalar velocity was automatically promoted to a 3-vector) 1274 1275 Nov 25, 1998 J. Apostolakis 1276 ----------------------------- 1277 - Added the direction to LocateGlobalPointAndUpdateTouchable. 1278 1279 Nov 19, 1998 J. Apostolakis (transport-00-03-04) 1280 ------------------------------ 1281 - Fixes: 1282 1) The final energy is set equal to the initial energy, because 1283 the PropagatorInField does not calculate it correctly yet. NEEDS Fix 1284 2) If the requested step size is zero and safety is zero, the 1285 step is now considered geometry limited. (This can happen 1286 if a discrete process tries to take a step that is very small 1287 compared to the mean free path.) Problem observed by Laszlo in EM tests. 1288 3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity. 1289 1290 Nov 11, 1998 J. Apostolakis (transport-00-03-03) 1291 ------------------------------ 1292 - Changes to accomodate new interface of Field: 1293 G4PropagatorInField and G4FieldTrack. 1294 1295 Oct 30, 1998 J. Apostolakis (transport-00-03-02) 1296 ----------------------------- 1297 - In the case of magnetic field, a flag that determines whether the 1298 geometry limited the step was not set. 1299 1300 Sep 16, 1998 J. Apostolakis (transport-00-03-01) 1301 ----------------------------- 1302 - Checks whether the particle is out of the world volume, 1303 if so it has exited and must be killed. 1304 1305 Aug 28, 1998 J. Apostolakis 1306 ----------------------------- 1307 - The PostStepGetPhysicalInteractionLength has fixed (to return kInf) 1308 The boolean flags for touchables are now initialised. & Other small fixes ? 1309 Test code for non-relocating case added (for debugging). 1310 1311 June 08, 1998 J. Apostolakis (trans-06-04) 1312 ------------------------------ 1313 - Corrected Safety computation for the case of the field (adding endpoint 1314 distance instead of curve length.) 1315 - Added PostStepDoIt method that tries to relocate the particle using 1316 G4ParticleChangeForTransport 1317 - Transportation is no longer a G4ContinuousProcess. 1318 1319 June 08, 1998 J. Apostolakis (trans-06-03) 1320 ------------------------------ 1321 - Modified it to recomputate Safety at the start of a step. To do this 1322 it uses the previous step's calculated safety and endpoint. 1323 1324 June 08, 1998 J. Apostolakis (trans-06-02) 1325 ------------------------------ 1326 - Modified it to add re-computation of Safety at the endpoint of a step, 1327 when the safety would become negative. This is done to allow processes 1328 to benefit from a realistic (geometrical) value of the safety. The 1329 request to do this was from EM physics 1330 1331 June 03, 1998 J. Apostolakis (trans-06-01) 1332 ------------------------------ 1333 - The safety we is now generalised to mean the limit of assumption of all 1334 processes. The AlongStepGPIL input value is not the remainder from the 1335 previous step's geometrical safety. 1336 So the transportation must recalculate the starting point's safety here. 1337 As a zeroeth order approximation we set it to zero. 1338 1339 April 17, 1998 M. Maire [recorded by John Apostolakis] 1340 ------------------------ 1341 - A new process, G4UserSpecialCuts, was added to allow the 1342 user an alternative method to set some user cuts. 1343 1344 April 15, 1998 H. Kurasige [recorded by John Apostolakis] 1345 --------------------------- 1346 - The transportation does the absolute minimum required to conform to 1347 the new scheme for ParticleChange: G4VParticleChange is used in signature. 1348 [ But default G4ParticleChange is still used ]. 1349 1350 April 14, 1998 John Apostolakis 1351 -------------------------------- 1352 - History file Created
