|---|
| 7 | List of fixes included in this public patch since release 6.2-patch-01: |
|---|
| 8 | |
|---|
| 9 | o Geometry: |
|---|
| 10 | -------- |
|---|
| 11 | + divisions: |
|---|
| 12 | o Removed unnecessary debug printout in method |
|---|
| 13 | G4PVDivision::CheckAndSetParamenters(). |
|---|
| 14 | + management: |
|---|
| 15 | o G4Region: added map for storage of materials/cuts and methods for |
|---|
| 16 | handling registration of couples in the map, finding a couple |
|---|
| 17 | according to a given material, clearing the map's storage. |
|---|
| 18 | Extensions necessary to resolve correct update of material-cut |
|---|
| 19 | couples in parameterised geometries by material. |
|---|
| 20 | o G4LogicalVolume: added method UpdateMaterial() to refresh a |
|---|
| 21 | material/cut couple in the corresponding region. |
|---|
| 22 | Extension necessary to resolve correct update of material-cut |
|---|
| 23 | couples in parameterised geometries by material. |
|---|
| 24 | o Fixed G4RegionStore::Clean() to avoid deletion of world region. |
|---|
| 25 | + navigation: |
|---|
| 26 | o G4Navigator: corrected computation of fGrandMotherExitNormal in |
|---|
| 27 | ComputeStep() in the case where a not valid exit-normal exists. |
|---|
| 28 | o G4GeomTestSegment: fix to correctly determine whether starting |
|---|
| 29 | trajectory is entering or exiting the solid when the starting point |
|---|
| 30 | is on a surface. Added additional tests on solid consistencies |
|---|
| 31 | (from roundoff sometimes) to avoid incorrect overlap warnings. |
|---|
| 32 | Addresses problem reports #610 and #652. |
|---|
| 33 | o Dump out contents from the solid when a fatal G4Exception is thrown |
|---|
| 34 | from the navigators in ComputeStep(). |
|---|
| 35 | o Invoke G4LogicalVolume::UpdateMaterial() instead of SetMaterial() |
|---|
| 36 | for parameterised navigation in G4Navigator and specialised |
|---|
| 37 | G4ParameterisedNavigation. |
|---|
| 38 | Modification necessary to resolve correct update of material-cut |
|---|
| 39 | couples in parameterised geometries by material. |
|---|
| 40 | + solids/CSG: |
|---|
| 41 | o Fix in G4Cons::DistanceToIn(p,v) on fRmax surface and move in, |
|---|
| 42 | the condition became a bit more strict && determinant >=0, i.e. |
|---|
| 43 | intersections in addition to go in. |
|---|
| 44 | Fixes a rare problem of dIn=dOut=0 observed in 3 events over a |
|---|
| 45 | statistics of 10^8.. |
|---|
| 46 | o Fix in G4Sphere::DistanceToOut(p,v,...) on fRmin moving outside. |
|---|
| 47 | The bug showed 3 events of dIn=dOut=0 for 10^7 statistics in the |
|---|
| 48 | unit testing. |
|---|
| 49 | o Bug fix in G4Sphere::SurfaceNormal(p) for theta normals. |
|---|
| 50 | + solids/specific: |
|---|
| 51 | o G4VCSGfaceted: fix for rare anomalous situation in which |
|---|
| 52 | DistanceToOut(p,v,..) will report kInfinity, make an additional |
|---|
| 53 | check for the point p on the surface, in which case will report |
|---|
| 54 | zero. Addresses problem observed in G4Polyhedra and reported in #650. |
|---|
| 55 | |
|---|
| 56 | o Materials: |
|---|
| 57 | --------- |
|---|
| 58 | + Added protection in G4AtomicShells::GetNumberOfShells(Z). |
|---|
| 59 | Fixes problem report #643. |
|---|
| 60 | + Recalculate ionisation parameters after set of new mean ionisation |
|---|
| 61 | potential; added factor 2 to shell correction term. |
|---|
| 62 | |
|---|
| 63 | o Processes/cuts: |
|---|
| 64 | -------------- |
|---|
| 65 | + Fixed bug in G4ProductionCutsTable for the update of materials/cuts |
|---|
| 66 | couple for dynamic setups where material may vary, like in the case |
|---|
| 67 | of parameterization of detectors through material. |
|---|
| 68 | |
|---|
| 69 | o Electromagnetic processes: |
|---|
| 70 | ------------------------- |
|---|
| 71 | + lowenergy: |
|---|
| 72 | o Trivial fixes for removal of redundant semicolons in the code. |
|---|
| 73 | + utils: |
|---|
| 74 | o Fixed a problem of cut dependence of transmission energy of low |
|---|
| 75 | energy e- via thin foil |
|---|
| 76 | + xrays: |
|---|
| 77 | o Changed "StronglyForced" back to "Forced" in GetMeanLifeTime() for |
|---|
| 78 | the G4Scintillation process. |
|---|
| 79 | |
|---|
| 80 | o Hadronic Processes: |
|---|
| 81 | ------------------ |
|---|
| 82 | + models/cascade: |
|---|
| 83 | o Fixed bug in G4CascadeInterface for uncorrect deletion of dynamic |
|---|
| 84 | particles. Fixes problem report #645. |
|---|
| 85 | |
|---|
| 86 | o Optical Processes: |
|---|
| 87 | ----------------- |
|---|
| 88 | + Allow for unified model reflectivity parameters to also work in case |
|---|
| 89 | of dielectric_metal surfaces; in G4OpBoundaryProcess, use GetMaterial() |
|---|
| 90 | from G4StepPoint directly, sample reflectivity and apply unified model |
|---|
| 91 | reflection parameters only once even for rough dielectric/metal |
|---|
| 92 | surfaces. Fixes problem report #654. |
|---|
| 93 | + Fixed bug in G4PlaneVectorRand for G4OpBoundaryProcess and resample |
|---|
| 94 | 'theFacetNormal' for LobeReflection in DielectricMetal. |
|---|
| 95 | |
|---|
| 96 | o Run: |
|---|
| 97 | --- |
|---|
| 98 | + Updated date to run-manager. |
|---|
| 99 | |
|---|
| 100 | o Visualization: |
|---|
| 101 | ------------- |
|---|
| 102 | + OpenGL: G4OpenGLTransform3D.cc: simplified implementation for |
|---|
| 103 | GetMatrix() to allow for porting on future CLHEP series. |
|---|
| 104 | |
|---|
| 105 | o Examples: |
|---|
| 106 | -------- |
|---|
| 107 | + Updated reference outputs. |
|---|
| 108 | + electromagnetic/MuonProcesses |

|---|
| 118 | o Correctly defined all UI subdirectories. |
|---|
| 119 | o Modifications in RunAction for histograms management for JAIDA. |
|---|
| 120 | + electromagnetic/TestEm10 |
|---|
| 121 | o Removed obsolete processes from PhysicsList. |
|---|

|---|
| 123 | o Minor cleanup of PhysicsLists. |
|---|
