| 2 | + Geant4 9.0 - patch-01 Release Notes |
| 3 | + ----------------------------------- |
| 4 | + |
| 5 | + 28 August 2007 |
| 6 | + |
| 7 | +List of fixes included in this public patch since the public release 9.0: |
| 8 | + |
| 9 | + o Configuration: (*) |
| 10 | + ------------- |
| 11 | + + liblist.c: fixed problem affecting recent CygWin installations on |
| 12 | + Windows in parsing the buffer for the generation of libname.map. |
| 13 | + + binmake.gmk: defined OUT internal variable specifying the proper |
| 14 | + compilation/linking option to Unix or Windows compilers: '-o ' |
| 15 | + and '/Fe' respectively. Cleared <TAB> characters where not necessary. |
| 16 | + + SUN-CC.gmk: forced -xO2 as optimisation level. |
| 17 | + |
| 18 | + o Geometry: |
| 19 | + -------- |
| 20 | + + magneticfield: |
| 21 | + o Fix to DistChord() method for Helical Steppers: adopt 'special' case |
| 22 | + also for Ang<2pi not only for Ang<pi; use cos() in place of tan(), to |
| 23 | + improve CPU performance. |
| 24 | + o In G4HelixMixedStepper added possibility to call different steppers |
| 25 | + for small steps and add some statistics how offen different steppers |
| 26 | + are called. Improved AdvanceHelix() to be able to make half step and |
| 27 | + full step in one call. |
| 28 | + o G4RKG3_Stepper: improved internal algorithm to use pre-computed values; |
| 29 | + the stepper now gives comparable CPU performance as ClassicalRK4. |
| 30 | + o Changed FatalException to EventMustBeAborted in AccurateAdvance() |
| 31 | + if proposed integration step is negative. (*) |
| 32 | + + management: |
| 33 | + o Added dummy constructor and destructor to G4VPVParameterisation. |
| 34 | + + solids/BREPS: |
| 35 | + o Added missing initialisations of kCarTolerance in alternative |
| 36 | + constructors for G4BoundingBox3D, G4Curve, G4CurveRayIntersection, |
| 37 | + G4KnotVector. Addressing problem report #959. |
| 38 | + + solids/CSG: |
| 39 | + o G4Tubs: fixed bug in DistanceToOut(p,v,..) for negative value under |
| 40 | + sqrt() for the case of point p on the surface and v tangent to the |
| 41 | + surface. Responsible for rare cases of NaN. |
| 42 | + + solids/specific: |
| 43 | + o Fixes in G4Polyhedra::GetPointOnSurface(): (*) |
| 44 | + Correctly treat 'totalPhi' instead of 'endPhi' for the case of open |
| 45 | + shapes and 'twopi' for not open shapes. |
| 46 | + Introduced fix for the case when number of sectors (numSide) is equal |
| 47 | + to 1. At the origin of problems observed when checking overlaps for |
| 48 | + polyhedra solids defined as such. |
| 49 | + o Fixed dummy constructors of G4Polycone and G4PolyPhiFace for |
| 50 | + initialisation of 'edges' and 'corners'. Added workaround to |
| 51 | + initialisation of 'corners' vector in G4PolyconeSide class, to allow |
| 52 | + for object persistency with Root-I/O. |
| 53 | + o G4EllipticalCone: |
| 54 | + - DistanceToIn(p): corrected answer for p.z()<-zTopCut and for the |
| 55 | + point p on the surface. |
| 56 | + - DistanceToOut(p,v): now returning positive solution or zero when |
| 57 | + crossing the elliptical surface. |
| 58 | + - Fix in DistanceToOut(p) which was giving always zero. |
| 59 | + - Added some formulas on how to pre-calculate 'SemiAxis' and 'zheight'. |
| 60 | + |
| 61 | + o Global: |
| 62 | + ------ |
| 63 | + + Changed date for patch-01 to release 9.0. |
| 64 | + |
| 65 | + o Graphics Representations: |
| 66 | + ------------------------ |
| 67 | + + Corrected graphical description for G4EllipticalCone in HepPolyhedron |
| 68 | + and G4Polyhedron. |
| 69 | + + G4VGraphicsScene: Added default constructor and virtual destructor. |
| 70 | + |
| 71 | + o Intercoms: |
| 72 | + --------- |
| 73 | + + G4UIbatch: |
| 74 | + o Bug fixed for the treatment of the last line. |
| 75 | + o Added support for continued line by '\', '_'. |
| 76 | + o String after '#' is treated as comment. |
| 77 | + o White spaces at the head of a line are allowed. |
| 78 | + o Fixed problem on 32bit-Linux. |
| 79 | + + G4UImanager: fixed bug concerning invalid returned object. |
| 80 | + + Introduced "/control/getEnv" and "/control/echo" commands. |
| 81 | + |
| 82 | + o Electromagnetic Processes: |
| 83 | + ------------------------- |
| 84 | + + Polarisation: |
| 85 | + o Removed/renamed obsolete methods and local variables in |
| 86 | + classes G4VPolarizedCrossSection, G4eplusPolarizedAnnihilation, |
| 87 | + and G4PolarizedAnnihilationModel to clear "shadow" warnings on SUN-CC. |
| 88 | + + Standard: |
| 89 | + o G4UniversalFluctuation: added protection such that no sampling of |
| 90 | + fluctuations is done if mean energy loss at the step is below minimal |
| 91 | + excitation energy of the media. The fix is important for cases of |
| 92 | + low-dense gases and very small steps. |
| 93 | + o G4UniversalFluctuation: added protection for low-density materials |
| 94 | + or very small steps - mean energy loss below minimal excitation |
| 95 | + energy - no fluctuation sampling but mean energy loss. |
| 96 | + + Utils: |
| 97 | + o G4VEmModel: fixed SelectRandomAtom() method for the selection of |
| 98 | + elements in a compound material. |
| 99 | + + Xrays: |
| 100 | + o G4VXTRenergyLoss: fixed Valgrind run-time errors for wrong memory |
| 101 | + allocation by removing internal initialisation of Sandia table and |
| 102 | + using Sandia table from materials. |
| 103 | + |
| 104 | + o Hadronic Processes: |
| 105 | + ------------------ |
| 106 | + + models/chiral_inv_phase_space: (*) |
| 107 | + o G4QuasiFreeRatios: fixed DB filling (ID update), responsible for |
| 108 | + excessive growth of memory in long runs. Corrected indexing and |
| 109 | + computation of cos(theta). |
| 110 | + + models/neutron_hp: |
| 111 | + o G4NeutronHPThermalScattering: removed duplicate declaration of |
| 112 | + 'dirName', already a class member, to clear compilation warning. |
| 113 | + + models/util: |
| 114 | + o G4KineticTrack: changed local variable names to clear compilation |
| 115 | + warnings on SUN-CC about hiding. |
| 116 | + + stopping: |
| 117 | + o Fixed signature of G4MuMinusCaptureCascade::DoCascade() expecting |
| 118 | + 'const' as arguments for A and Z. Resolves linking problems on SUN-CC. |
| 119 | + |
| 120 | + o Visualization: |
| 121 | + ------------- |
| 122 | + + Removed redundant method declarations and minor tidies. |
| 123 | + |
| 124 | + o Environments: |
| 125 | + ------------ |
| 126 | + + Minor bug fixes to G4Py module; updated geometry wrappers and TestEm0 |
| 127 | + example. |
| 128 | + |
| 129 | + o Examples: |
| 130 | + -------- |
| 131 | + + advanced/medical_linac: |
| 132 | + o Fixed problem report #880 in DetectorConstruction class. |
| 133 | + o Updated macros; reviewed seed initialisation and modified to use |
| 134 | + default multiple-scattering class instead of MultipleScattering52. |
| 135 | + + advanced/microbeam: |
| 136 | + o Improved dose calculation in the code in order to take into account |
| 137 | + small energy deposits by any particle around the phantom edge voxels, |
| 138 | + by suppressing a selection condition on the PostStep. The total result |
| 139 | + of the dose calculation does not change significantly. |
| 140 | + o Added protection against scattering at large angles in collimators. |
| 141 | + o Suppressed field manager in zones with zero field. |
| 142 | + o Use 'kUndefined' optimization in cell phantom implementation. |
| 143 | + o Changed number of incident alpha particles in microbeam.mac. |
| 144 | + + advanced/underground_physics: |
| 145 | + o Added missing header file G4hIonisation.hh to DMXPhysicsLists |
| 146 | + translation unit. |
| 147 | + o Added G4StepLimiter to physics list as correction of migration |
| 148 | + required since Geant4 release 7.0. |

| 150 | + o Updated README for physics-list names. |
| 151 | + + extended/electromagnetic/TestEm8: |
| 152 | + o Fixed PAI physics constructors: energy loss processes should be |
| 153 | + active post step. |
| 154 | + o Create VisManager only for interactive session, improved destructor |
| 155 | + of Em8DetectorConstruction class. |
| 156 | + + extended/electromagnetic/TestEm10: |
| 157 | + o Create VisManager only for interactive session, improved destructor |
| 158 | + of Em10DetectorConstruction class. |
| 159 | + + extended/electromagnetic/TestEm13: |

| 161 | + o SteppingAction : modify logic to take into account low energy packages. |
| 162 | + + extended/medical/fanoCavity: |
| 163 | + o Use 'fUseDistanceToBoundary' in physics-list for 'emOptions'. Cleanup. |
| 164 | + + extended/medical/GammaTherapy: |
| 165 | + o Provide possibility to change cuts between runs. |
| 166 | + + extended/radioactivedecay/exrdm: |
| 167 | + o Removed obsolete hadronic builders and use only QGSP_BIC, |
| 168 | + QGSP_BIC_HP, QGSP_BERT, QGSP_BERT_HP instead. |
| 169 | + + novice/N02: |
| 170 | + o Fixed implementation of ExN02MagneticField class in way field is set. |
| 171 | + |
