---|
| 8 | |
---|
| 9 | o Configuration: |
---|
| 10 | ------------- |
---|
| 11 | + Fixed in liblist.c use of gets() by adopting safer fgets(). |
---|
| 12 | + Linux-icc.gmk: updated setup to make use of icc-10.1 and ifort-10.1; |
---|
| 13 | changed compilation option "-mp" to more performant "-fp_model precise". |
---|
| 14 | + Linux-g++.gmk: Replaced g77 with gfortran compiler. |
---|
| 15 | |
---|
| 16 | o Environments: |
---|
| 17 | ------------ |
---|
| 18 | + Fixed compilation problems. |

---|
| 20 | |
---|
| 21 | o Geometry: |
---|
| 22 | -------- |
---|
| 23 | + Cleared compilation warnings detected on gcc-4.3.0. |
---|
| 24 | + magneticfield: |
---|
| 25 | o Fixed 'unused' non-initialized values of dydx in classes |
---|
| 26 | G4EqMagElectricField and G4EqEMFieldWithSpin. |
---|
| 27 | + management: |
---|
| 28 | o Added missing protected copy-contructor and assignment operator |
---|
| 29 | for G4VSolid. |

| 32 | + navigation: |
---|
| 33 | o G4PathFinder: commented out warning and exception in ComputeStep() |
---|
| 34 | for steps smaller than minimum threshold. |
---|
| 35 | + solids/CSG: |
---|
| 36 | o G4Cons: added protection against NaN in GetPointOnSurface() in the |
---|
| 37 | case the check is run for Rmax1==Rmax2. |

---|
| 39 | Addressing problem report #934. |
---|
| 40 | + solids/specific: |
---|
| 41 | o G4ExtrudedSolid: bug fix in MakeFacets() to fill 'fTriangles' also |
---|
| 42 | in case of polygon with 3 or 4 vertices, as they are needed for |
---|
| 43 | Inside(p). Fix in Inside(p) for correctly handling the case of |
---|
| 44 | points located on the edges of triangles which are not the outline |
---|
| 45 | edges of the polygon. |
---|
| 46 | o G4TessellatedSolid: fixed bug in copy-constructor and internal method |

| 48 | compute normal only if specified by flag in input. |
---|
| 49 | o G4Polyhedra: fixed problem of out-of-bound access to vectors in |
---|
| 50 | method GetPointOnSurface(). |

| 51 | o G4IntersectingVone: added protection against NaN in LineHitsCone1() |
---|
| 52 | in case of configurations where a conic section becomes a tube. |
---|
| 53 | Added kCarTolerance in definition of "low" and "high" cone limits |
---|
| 54 | in R and in Z in order to protect against numerical errors; this |
---|
| 55 | fixes cases of DistanceToIn(p,v) returning 'kInfinity' when p+t*v |
---|
| 56 | cross intersection between two cones. |
---|
| 57 | o G4EllipticalCone: removed some debug printouts. |
---|
| 58 | o G4Hype: refined polyhedron representation for correct visualization |
---|
| 59 | of the shape. |
---|

---|
| 64 | templates.hh respectively for porting on gcc-4.3.0 compiler. |
---|
| 65 | + Cleared compilation warnings detected on gcc-4.3.0 |
---|
| 66 | + Removed useless specification of units in implementation of |
---|
| 67 | G4GeometryTolerance::SetSurfaceTolerance(). |
---|
| 68 | + Changed date for patch-02 to release 9.1. |
---|
| 69 | |
---|

---|
| 75 | |
---|
| 76 | o Materials: |
---|
| 77 | --------- |
---|
| 78 | + G4NistMaterialBuilder: using correct dimension for the density for |
---|
| 79 | ConstructNewMaterial() methods. |
---|
| 80 | + G4Material: improved printout in error conditions by specifying the |
---|
| 81 | name of the material affected. |
---|
| 82 | |
---|
| 83 | o Particles: |
---|
| 84 | --------- |
---|
| 85 | + G4ParticleTable: fixed implementation of methods Remove() and |
---|
| 86 | RemoveAllParticles() so that particle definition objects are properly |
---|
| 87 | deleted when invoking these methods between runs. It's user's |
---|
| 88 | responsibility to delete dynamically instantiated particle objects. |
---|
| 89 | Added method DeleteAllParticles() to remove and delete all particles |
---|
| 90 | in the list. Addressing problem report #1007. |
---|
| 91 | + Fixed bugs in G4Iontable::Remove() and G4ShortLivedTable::Remove(). |

| 92 | |
---|
| 93 | o Physics Lists: |
---|
| 94 | ------------- |
---|
| 95 | + Fixed deletion using uninitialized pointers in FTF-BIC, for classes |
---|
| 96 | HadronPhysicsFTF_BIC, G4FTFBinaryNeutronBuilder and G4LEPNeutronBuilder. |
---|
| 97 | |
---|
| 98 | o Electromagnetic Processes: |
---|
| 99 | ------------------------- |
---|
| 100 | + Standard: |
---|
| 101 | o G4UrbanMscModel90, G4UrbanMscModel: fixed asymmetry of lateral |
---|
| 102 | displacement. |
---|
| 103 | o G4ionIonisation: adopt 'linLossLimit' 0.15 as it was originally in 9.1. |
---|
| 104 | o G4IonFluctuations: fixed discontinuity of width correction factor |
---|
| 105 | for small velocities and added a protection to its value |
---|
| 106 | (factor>1), which fixes very long alpha events. |
---|
| 107 | + Utils: |
---|
| 108 | o G4EmCorrections: set finite size correction to zero (provides flat |
---|
| 109 | distribution of vertex detector response for high energy hadrons). |
---|
| 110 | o G4ionEffectiveCharge: minor change of numerical constants to provide |
---|
| 111 | continuous change of charge versus energy. |
---|
| 112 | |
---|
| 113 | o Hadronic Processes: |
---|
| 114 | ------------------ |
---|
| 115 | + Cleared most compilation warnings detected on gcc-4.3.0. |
---|
| 116 | + cross_sections: |
---|
| 117 | o G4NeutronInelasticCrossSection: fixed bug which used to return zero |
---|
| 118 | cross section for 3He. |
---|
| 119 | o G4TripathiLightCrossSection: fixed bug in method IsApplicable() to |
---|
| 120 | use GetN() instead of GetA() for target. |
---|
| 121 | o Added capability to use element-based cross section data |
---|
| 122 | sets if no isotope-based ones are available. This is required to |
---|
| 123 | get the HP neutron code to work within the cross section framework |
---|
| 124 | introduced in version 9.0. Added internal method to class |
---|
| 125 | G4CrossSectionDataStore. |
---|
| 126 | + models/cascade: |
---|
| 127 | o Added Coulomb barrier in G4EquilibriumEvaporator. |
---|
| 128 | o Changed pp, nn total cross section parameterization in class |
---|
| 129 | G4CascadSpecialFunctions to more closely reflect the PDG values; |
---|
| 130 | fixed cross section bug responsible for returning low or zero total |
---|
| 131 | cross sections for pi-p, pi+n, np, and pi0 interactions. |
---|
| 132 | + models/chiral_inv_phase_space: |
---|
| 133 | o Modified G4QElasticCrossSection to fix problem with quasi-elastic. |
---|
| 134 | When run together with elastic, the parameters to sample T were not |
---|
| 135 | updated, this fix is to always update these. |
---|
| 136 | o Fixed case of exceeded boundary bounds in G4QCollision. |
---|
| 137 | o Check on tolerance is replaced by check on exact equality for fixing |
---|
| 138 | event reproducibility. |
---|
| 139 | + models/coherent_elastic: |
---|
| 140 | o G4HadronElastic: added extra protection against precision lost |
---|
| 141 | when projectile almost lost kinetic energy; set 'lowestEnergyLimit' |
---|
| 142 | to be 1.e-6*eV (was 0.0). |
---|
| 143 | Added extra protection: if sampled t out of the physics range then |
---|
| 144 | no scattering. |
---|
| 145 | o G4UHadronElasticProcess: call to G4QElasticCrossSection with option |
---|
| 146 | "false", so parameters for sampling of scattering are precalculated. |
---|
| 147 | + models/neutron_hp: |
---|
| 148 | o Fix against cases of division by zero. |
---|
| 149 | o Fixed erroneous condition in G4NeutronHPContAngularPar. |
---|
| 150 | o To increase performance, checking point of "neglecting doppler |
---|
| 151 | broadening" flag is changed from GetCrossSection() method to |
---|
| 152 | BuildPhysicsTable(). |
---|
| 153 | + models/theo_high_energy: |
---|
| 154 | o Added missing Fermi momentum to quasi elastic scattering. |
---|
| 155 | + stopping: |
---|

---|
| 161 | o Added protection to properly handle shortlived particles with finite |
---|
| 162 | pre-assigned proper time. |
---|
| 163 | + Management: |
---|
| 164 | o Fixed bug related to invoking ResetNumberOfInteractionLengthLeft() |

---|
| 171 | --- |
---|
| 172 | + Added G4Transportation to shortlived particles in G4VUserPhysicsList |
---|
| 173 | in order to fix problem of non-assigned process for shortlived particle |
---|
| 174 | decay detected in CMS. |
---|
| 175 | |
---|

---|
| 177 | -------- |
---|
| 178 | + advanced/underground_physics: |
---|
