|---|
| 7 | List of fixes included in this public patch since the public release 8.0: |
|---|
| 8 | |
|---|
| 9 | o Digits & Hits: |
|---|
| 10 | ------------- |
|---|
| 11 | + Added missing methods in G4VDigiCollection and G4TDigiCollection. |
|---|
| 12 | Addresses problem report #786. |
|---|
| 13 | |
|---|
| 14 | o Geometry: |
|---|
| 15 | -------- |
|---|
| 16 | + divisions |
|---|
| 17 | o Added missing setting of mother-logical pointer in constructors of |
|---|
| 18 | G4PVDivision. Fixes problem report #829. |
|---|
| 19 | o Added missing checks for illegal constructs of G4PVDivision (NULL |
|---|
| 20 | pointer to mother logical and self-placement). |
|---|
| 21 | o Fixed check for generic construct in G4ParameterisationPolycone and |
|---|
| 22 | G4ParameterisationPolyhedra: allow it for the automatic replicated |
|---|
| 23 | instance. |
|---|
| 24 | o Cache information about axis of division and provided accessor method |
|---|
| 25 | GetDivisionAxis() in G4PVDivision. |
|---|
| 26 | + navigation |
|---|
| 27 | o Addressing problem with convergence in LocateIntersectionPoint() |
|---|
| 28 | of G4PropagatorInField. The problem, identified by Atlas, was |
|---|
| 29 | observed when requesting high precision, i.e. small values of |
|---|
| 30 | eps_min/max, delta_one_step, due to need for small delta_intersection. |
|---|
| 31 | Increased maximum iterations (from 100 to 10000) until correct |
|---|
| 32 | information can be return an Exception is thrown in case of too many |
|---|
| 33 | iterations; a warning is thrown in case over 1000 iterations. |
|---|
| 34 | + solids/BREPS |
|---|
| 35 | o Use explicit 'HepGeom' namespace for 'Identity', to allow for |
|---|
| 36 | porting on Windows/VC++ when using CLHEP-2.0.X. |
|---|
| 37 | + solids/CSG |
|---|
| 38 | o G4Sphere: fixed bug in DistanceToOut() for theta intersections. |
|---|
| 39 | Fixes problem report #830. |
|---|
| 40 | + solids/specific |
|---|
| 41 | o Fixed visibility of soft edges for visualization of twisted solids. |
|---|
| 42 | o G4TwistedTubs and G4VTwistedFaceted::CreatePolyhedron(): changed |
|---|
| 43 | parameterised polyhedron mesh approximation in terms of |
|---|
| 44 | G4Polyhedron::GetNumberOfRotationSteps(). |
|---|
| 45 | o Fixes in G4EllipticalCone: |
|---|
| 46 | - Changed GetPointOnSurface(), which was not uniform in endcaps. |
|---|
| 47 | - Bug fix in Inside(), which was not correct for the elliptic mantel. |
|---|
| 48 | Made test similar as in G4EllipticTube. |
|---|
| 49 | - Several fixes in DistanceToIn/Out() resolving problems of looping |
|---|
| 50 | events. |
|---|
| 51 | + volumes |
|---|
| 52 | o G4AssemblyVolume: fixed initialisation of names for placed volumes |
|---|
| 53 | which was corrupted after migration to <sstream> as side effect. |
|---|
| 54 | |
|---|
| 55 | o Particles: |
|---|
| 56 | --------- |
|---|
| 57 | + Bug fix for G4ParticleDefinition, was causing improper behavior of |
|---|
| 58 | GetAtomicNumber() method for ions. Fixes problem report #827. |
|---|
| 59 | |
|---|
| 60 | o Electromagnetic processes: |
|---|
| 61 | ------------------------- |
|---|
| 62 | + standard: |
|---|
| 63 | o Fix in G4PolarizedComptonScattering, returning PostStepDoIt() |
|---|
| 64 | for G4ComptonScattering52. Fixes problem report #478. |
|---|
| 65 | |
|---|
| 66 | o Hadronic Processes: |
|---|
| 67 | ------------------ |
|---|
| 68 | + management: |
|---|
| 69 | o G4HadronicProcess: fixed problem report #611. Problems caused when |
|---|
| 70 | hadronic interactions reset stopButAlive particle to Alive. |
|---|
| 71 | o Added diagnostics when hadronic exceptions occur in G4HadronicProcess |
|---|
| 72 | and G4EnergyRangeManager. |
|---|
| 73 | + models/binary_cascade: |
|---|
| 74 | o Fixed problem report #794. Projectile nucleus needs to be centered. |
|---|
| 75 | + models/chiral_inv_phase_space/body: |
|---|
| 76 | o Fixed trivial compilation warning. |
|---|
| 77 | + models/de_excitation: |
|---|
| 78 | o G4NuclearLevelManager: print a warning if no data file is present. |
|---|
| 79 | Addressed problem report #814. |
|---|
| 80 | o G4ParaFissionModel: fix for compilation error, following problem |
|---|
| 81 | report #817. |
|---|
| 82 | + models/neutron_hp: |
|---|
| 83 | o Fixes core dump observed when neutron energy is close to 20 MeV. |
|---|
| 84 | + models/radioactive_decay |
|---|
| 85 | o G4NuclearDecayChannel::BetaDecayIt(): check for negative sqrt() |
|---|
| 86 | argument in 'daughtermomentum[1]'. Fixes problem report #822. |
|---|
| 87 | + stopping: |
|---|
| 88 | o Set process type to be 'fHadronic'. Was not set previously. |
|---|
| 89 | + util: |
|---|
| 90 | o G4ReactionDynamics: added array bounds protection in TwoCluster(). |
|---|
| 91 | |
|---|
| 92 | o Processes cuts: |
|---|
| 93 | -------------- |
|---|
| 94 | + Fix in G4VRangeToEnergyConverter::Convert() to recalculate the energy |
|---|
| 95 | loss table if new elements are added. Fixes problem report #831. |
|---|
| 96 | |
|---|
| 97 | o Track: |
|---|
| 98 | ----- |
|---|
| 99 | + G4ParticleChangeForRadDecay is now derived from G4ParticleChangeForDecay. |
|---|
| 100 | |
|---|
| 101 | o Transportation: |
|---|
| 102 | -------------- |
|---|
| 103 | + G4Transportation: the particle's charge is now taken from the dynamic |
|---|
| 104 | particle, so that it can take into account changes from the interaction |
|---|
| 105 | of an ion with matter (eg stripping e-). |
|---|
| 106 | + Corrected problem with suspended tracks, addressing problem report #802. |
|---|
| 107 | Added StartTracking() method which takes over responsibility to clear |
|---|
| 108 | the state for a new track, and to message other relevant component to |
|---|
| 109 | clear their state. |
|---|
| 110 | |
|---|

|---|
| 117 | + RayTracer: |
