|---|
| 7 | List of fixes included in this public patch to release 5.1: |
|---|
| 8 | |
|---|
| 9 | o Electromagnetic processes (standard): |
|---|
| 10 | ------------------------------------ |
|---|
| 11 | + muons: |
|---|
| 12 | - Commented out debug printout in G4MuPairProduction. |
|---|
| 13 | |
|---|
| 14 | o Geometry: |
|---|
| 15 | -------- |
|---|
| 16 | + solids/Boolean: |
|---|
| 17 | - Added set/get methods for scale precision in G4ReflectionFactory. |
|---|
| 18 | + volumes: |
|---|
| 19 | - G4PropagatorInField.cc: fix in ComputeStep() to avoid step computation |
|---|
| 20 | if proposed step length is too small. Fixes problem noticed in release |
|---|
| 21 | 5.1 and occasionally appearing as "Invalid Enum in [solid-type]", also |
|---|
| 22 | registered as problem report #485. |
|---|
| 23 | |
|---|
| 24 | o Hadronic processes: |
|---|
| 25 | ------------------ |
|---|
| 26 | + models/generator/kinetic_model |
|---|
| 27 | o G4BinaryCascade: fix to cure infinite loop observed in inelastic |
|---|
| 28 | scattering of hydrogen. |
|---|
| 29 | |
|---|
| 30 | o Run: |
|---|
| 31 | --- |
|---|
| 32 | - G4RunManager: fixed behavior of function DefineWorldVolume() |
|---|
| 33 | to properly reset navigation history and optimisation in case the |
|---|
| 34 | topology of the geometry has changed between runs. Now only a single |
|---|
| 35 | call to DefineWorldVolume() is necessary when changing the geometry. |
|---|
| 36 | Fixes also problem report #481. |
|---|
| 37 | o Added new boolean argument (default set to TRUE) to specify if |
|---|
| 38 | topology has changed. |
|---|
| 39 | o Forced open/close geometry in method ResetNavigator() to properly |
|---|
| 40 | reset G4Navigator status and remove old optimisations. |
|---|
| 41 | |
|---|
| 42 | o Examples: |
|---|
| 43 | -------- |
|---|
| 44 | - novice/N04 |
|---|
| 45 | o Corrected printout. |
|---|
| 46 | - extended/electromagnetic - TestEm1, TestEm2, TestEm3 |
|---|
| 47 | o Simplified mechanism for updating geometries between runs, |
|---|
| 48 | according to changes in G4RunManager::DefineWorldVolume(). |
|---|
| 49 | |

| 52 | Technical Notes |
|---|
| 53 | --------------- |
|---|

|---|
| 56 | o Technical notes distributed for release 5.1 are also applicable and |
|---|
| 57 | valid for this patch. |
