|---|
| 8 | |
|---|
| 9 | o Config: |
|---|
| 10 | ------ |
|---|
| 11 | - Upgraded WIN32-g++ setup to compile with -ansi and gcc-2.95.3 for |
|---|
| 12 | most recent versions of CygWin. |
|---|
| 13 | |
|---|
| 14 | o Electromagnetic processes (low-energy): |
|---|
| 15 | -------------------------------------- |
|---|
| 16 | - Bug fix in delta-electron spectra. |
|---|
| 17 | - Bug fix in simulation of EM processes in compounds. |
|---|
| 18 | - Optimised loading of data in G4AugerData. |
|---|
| 19 | |
|---|
| 20 | o Event: |
|---|
| 21 | ----- |
|---|
| 22 | - G4PrimaryParticle: |
|---|
| 23 | o Bug fixed in the initialisation of 'charge' for all constructors. |
|---|
| 24 | |
|---|
| 25 | o Geometry: |
|---|
| 26 | -------- |
|---|
| 27 | + magnetic-field: |
|---|
| 28 | - G4FieldManager: |
|---|
| 29 | o made 'fDefault_Delta_One_Step_Value' and |
|---|
| 30 | 'fDefault_Delta_Intersection_Val' non static constants to resolve |
|---|
| 31 | initialisation problems. Fixes problem report #383. |
|---|
| 32 | - G4ChordFinder: |
|---|
| 33 | o in NewStep, fixed case of stepTrial >> stepTrialOld, to take |
|---|
| 34 | large multiple - not small |
|---|
| 35 | o added guard for stepTrial==0.0 in FindNextChord(). |
|---|
| 36 | - G4MagIntegratorDriver: |
|---|
| 37 | o added protection against error of 0.0 in ComputeNewStepSize. |
|---|
| 38 | o cleared warning of unused variable. |
|---|
| 39 | - G4EquationOfMotion: |
|---|
| 40 | o made RightHandSide() an inline method |
|---|
| 41 | o in GetFieldValue() signature of Point is double[4], |
|---|
| 42 | instead of double[3] |
|---|
| 43 | o defined G4maximum_number_of_field_components as enum. |
|---|
| 44 | + solids/CSG: |
|---|
| 45 | - G4Cons: |
|---|
| 46 | o Bug fixed in DistanceToIn(p,v) concerning z-crossing at |
|---|
| 47 | the edge with Rmin,Rmax. |
|---|
| 48 | + solids/STEP: |
|---|
| 49 | - Fixed GNUmakefile to parse 'g++' string in G4SYSTEM to detect |
|---|
| 50 | non-ISO setup for gcc-2.95 and higher. |
|---|
| 51 | + solids/STEPinterface: |
|---|
| 52 | - Fixed GNUmakefile to parse 'g++' string in G4SYSTEM to detect |
|---|
| 53 | non-ISO setup for gcc-2.95 and higher. |
|---|
| 54 | + verification: |
|---|
| 55 | - G4GeomTestVolume: |
|---|
| 56 | o Fixed recursive call to G4GeomTestVolume to consider also |
|---|
| 57 | 'tolerance' as argument in the recursive test algorithm. |
|---|
| 58 | + volumes: |
|---|
| 59 | - Code cleanup and cosmetics for most classes. |
|---|
| 60 | - G4PropagatorInField: |
|---|
| 61 | o In ComputeStep(), reset status to original by setting 'fNoZeroStep' |
|---|
| 62 | to zero if (fNoZeroStep > fAbandonThreshold_NoZeroSteps). |
|---|
| 63 | Fixes a problem observed in cases when a looping track is killed, |
|---|
| 64 | the bug was causing also subsequent tracks to be killed. |
|---|
| 65 | o Removed not-implemented constructor taking G4Navigator* as argument. |
|---|
| 66 | o Get rid of static const data for default 'epsilonStep' size. |
|---|
| 67 | o Initialised all data members in constructor! |
|---|
| 68 | |
|---|
| 69 | o Global: |
|---|
| 70 | ------ |
|---|
| 71 | - G4Allocator: |
|---|
| 72 | o Moved page size to become data-member of G4Allocator. |
|---|
| 73 | 'fPageSize' is now computed according to the size of the object |
|---|
| 74 | to be allocated. The default size is 1024 bytes for objects whose |
|---|
| 75 | size is less than 512 bytes, 10 times the size of the object otherwise. |
|---|
| 76 | |
|---|
| 77 | o Hadronic processes: |
|---|
| 78 | ------------------ |
|---|
| 79 | + management, utils, models/high_energy: |
|---|
| 80 | o Introduced accounting of strange baryons. |
|---|
| 81 | o Introduced accounting for anti-nucleons and strange mesons. |
|---|
| 82 | o Improved treatement of inelasticity for annihilation events and pion |
|---|
| 83 | absorptive reactions. |
|---|
| 84 | o Added protection in the call to phase-space method for pion induced |
|---|
| 85 | reactions. |
|---|
| 86 | o Fixed error in energy conservation observed by BTEV. |
|---|
| 87 | Used to show (1/500) for 1.5-2.5 GeV pion reactions in medium A nuclei. |
|---|
| 88 | + cross-sections: |
|---|
| 89 | o Fixed bug in caching information in gamma nuclear cross-sections |
|---|
| 90 | (G4PhotoNuclearCrossSection). |
|---|
| 91 | |
|---|
| 92 | o Examples: |
|---|
| 93 | -------- |
|---|
| 94 | - Corrected README in exampleN01. |
|---|
| 95 | - Updated reference outputs. |
|---|
| 96 | |
