---|
| 121 | |
---|
| 122 | Listed here is some relevant information on developments included in this |
---|
| 123 | release, some of which may require migrations (mainly for users of advanced |
---|
| 124 | Geant4 features) in order to upgrade from release 9.2 to release 9.3. |
---|
| 125 | Note that for all users a full re-installation of libraries (or a full |
---|
| 126 | recompilation) and a recompilation of user applications is required. |

---|
| 134 | particles before instantiating the physics processes. For example, |

| 148 | coherent approach for the modeling of electromagnetic physical interactions. |

---|
| 152 | physics-list(s) in order to use these new processes and models. |

| 228 | integrating the trajectories of charged particles in a magnetic field. |

| 229 | It uses the standard Nystrom method and a novel analytical estimation of |
---|
| 230 | the integration error. This reduces greatly the number of field calls per |
---|
| 231 | integration step (from 10 to 3). It achieves comparable accuracy with |
---|
| 232 | <TT>G4ClassicalRK4</TT> in test cases. It can be used only for pure |

| 236 | calculation or interpolation method. For positions within the chosen radius |

| 237 | of the previous position where it evaluated the field, it returns the last |

| 344 | <LI>New default builder for optical photon physics has been added: |

---|
| 376 | <LI>Improved ability of visualization system to render Boolean solids. |
---|
| 377 | Certain cases involving very near co-planar faces used to result in |
---|
| 378 | incorrect visualization (though not incorrect tracking). |
---|
| 379 | An existing mechanism to deal with this has been improved; this mechanism |
---|
| 380 | used to shift slightly the position of one solid in a chosen direction. |
---|
| 381 | Now it attempts shifts in different directions by varying small amounts |
---|
| 382 | until one is found that does not give an error. The system still can not |
---|
| 383 | handle every situation. However it results in far fewer visualization |
---|
| 384 | inaccuracies than were seen previously in such difficult cases.</LI> |
---|
| 385 | <LI>Visualization attributes can now be individually set for each volume within |
---|
| 386 | a nested parameterization.</LI> |
---|
| 387 | <LI>Rich Trajectories and Rich Trajectory Points now include additional |
---|
| 388 | information such as the complete volume path of the starting and ending |
---|
| 389 | volume including all replica and copy numbers, etc.</LI> |
---|
| 390 | <LI>A new command, <TT>/vis/viewer/set/targetPoint</TT>, sets a specific point |
---|
| 391 | to be the center of the view. Helps with doing extreme zoom in to a |
---|
| 392 | specific point.</LI> |
---|
| 393 | <LI><B>gMocrenFile</B>: First Beta release of this new visualization driver to |
---|
| 394 | output data in the <TT>gdd</TT> format used by the gMocren volume |
---|
| 395 | visualization tool. <TT>gMocrenFile</TT> can include volume data from |
---|
| 396 | sensitive detector volumes, or from command-based scoring meshes, in |
---|
| 397 | addition to detector geometry and trajectories. Use new command |
---|
| 398 | <TT>/vis/scene/add/psHits</TT> to add scorer hits to gMocren output. |

| 402 | a user session selected according to defined environment variables |
---|
| 403 | <TT>G4UI_USE_*</TT>.</LI> |
---|
| 404 | <LI><B>Qt</B>: Continued improvements to this new driver. The <TT>Qt</TT> |
---|
| 405 | visualization driver and the associated <TT>Qt</TT> User Interface now work |
---|
| 406 | well on almost all platforms and with both Qt3 and Qt4 (but still considered |
---|
| 407 | a Beta release due to a few rare combinations of commands on certain |
---|
| 408 | platforms that can cause crashes).</LI> |
---|
| 409 | <LI>PostScript printing: vector and bitmapped printing through the UI command |
---|
| 410 | <TT>/vis/ogl/printEPS</TT> is now fully functional for all OpenGL viewers |
---|
| 411 | (previously only for OGLIX and OGLSX). Related new commands are |
---|
| 412 | <TT>/vis/ogl/set/printSize</TT> and <TT>/vis/ogl/set/printFilename</TT>.</LI> |
---|
| 413 | <LI><B>HepRepFile</B>: new UI commands of the form <TT>/vis/heprep</TT> allow |
---|
| 414 | easy control of output file name and output directory, whether a file name |
---|
| 415 | should be reused (rather than having a sequential suffix appended at each |
---|
| 416 | new file) and whether culled geometry volumes should be included. |
---|
| 417 | Also fixed a bug in representation of <TT>G4Tubs</TT> which had caused |
---|
| 418 | wrong visualization for cases in which the tube was at an unusual angle.</LI> |

| 483 | <LI>Reports have been made of particle tracks stuck at a volume boundary or at |
---|

---|
| 485 | step per 10^11, but can effect large productions. The behaviour involved |

---|
| 487 | result the simulation of this track never finishes. |
---|
| 488 | <UL> |
---|
| 489 | <LI>A partial solution is implemented in this release, which uses an |
---|
| 490 | existing mechanism to identify better these stuck tracks. It is able to |
---|
| 491 | find all such tracks in the setups reported, using a large multiple of |
---|
| 492 | the value of the geometrical tolerance for the setup. Users should pay |
---|
| 493 | attention that the value is chosen well for their setup in case they |
---|
| 494 | encounter a similar problem (using the existing functionality for |
---|
| 495 | setting this value).</LI> |
---|
| 496 | <LI>The treatment for these stuck tracks is to abandon the relevant track. |
---|
| 497 | This results in the track being killed by the <TT>G4Transportation</TT> |
---|
| 498 | process. A warning is issued (if compiled in verbose mode, the default) |
---|
| 499 | in the case that the energy of the track is above a threshold energy. |
---|
| 500 | Its default value is <TT>100 MeV</TT>. This value should be chosen by |
---|
| 501 | a user in order to get warning for all particles of energy important to |
---|
| 502 | your simulation. A new value can be assigned using the |

| 2159 | <LI><TT>G01</TT>: added new GDML samples for matrices+loops and |
---|
| 2160 | optical-surfaces. Modified matricesandloops.gdml, following |
---|
| 2161 | new specifications for loops. |
---|
| 2162 | Added possibility to run application in batch mode giving a macro |
---|
| 2163 | as input (e.g.: <TT>load_gdml solids.gdml g01.gdml g01.in</TT>); |
---|
| 2164 | option to be used by system testing for batch test. |
---|
| 2165 | Added assembly.gdml to demonstrate support for 'assembly' tags. |
---|
| 2166 | Added usage of 'expression' and 'quantity' in solids.gdml.</LI> |
---|
| 2167 | <LI><TT>G02</TT>: |
---|
| 2168 | Added missing inclusion of headers after cleanup.</LI> |

| 2169 | <LI><TT>G03</TT>: |
---|
| 2170 | Extended example to show also capability to write extended schema; |
---|
| 2171 | added custom writer class. |
