9 History file for the Liege cascade INCL Model
10 ---------------------------------------------
12 This file should be used to summarize modifications introduced in the
13 code and to keep track of all tags.
15 ---------------------------------------------------------------
16 * Please list in reverse chronological order (last date on top)
17 ---------------------------------------------------------------
19 04 December 2007 - Gabriele Cosmo (hadr-incl-V09-00-09)
20 ---------------------------------
21 - Again commented out call to isnan() in G4Incl.cc for allow
22 porting to platforms other than Linux....
24 03 December 2007 - Pekka Kaitaniemi
25 -----------------------------------
26 - Added bugfixes to INCL nucleon array handling. Several off-by-one
27 bugs were fixed. These fixes help with INCL neutron energy spectra.
28 - 4-momentum conservation problem was noticed to be mainly ABLA
30 o INCL alone violates energy conservation only by less than 20 MeV.
31 o ABLA has problems with baryon number conservation. Some produced
32 nucleons are not given back to INCL and Geant4. This is probably the
33 main reason for 4-momentum conservation violations.
34 - Added 4-momentum and baryon number conservation checking code to the
35 interfaces (behind flag DEBUGINCL).
37 15 November 2007 - Pekka Kaitaniemi
38 -----------------------------------
39 - First fix to secondary particle Pt, Px and Phi distributions.
40 o Momentum x-component was transformed incorrectly from spherical to
41 cartesian coordinates.
43 08 November 2007 - Pekka Kaitaniemi
44 -----------------------------------
45 - Started using G4UniformRand as a random number generator.
46 o It is much more sophisticated generator than the original INCL one
48 o This should eliminate infinite loop in test runs on 64-bit
49 plattforms. The old generator probably was not 64-bit clean.
51 31 October 2007 - Gabriele Cosmo (hadr-incl-V09-00-05)
52 --------------------------------
53 - Again commented out calls to isnan() and isinf() in G4Abla.cc for allow
54 porting to platforms other than Linux.
56 30 October 2007 - Pekka Kaitaniemi
57 ----------------------------------
58 - Abla now runs. Integrated energy spectrums for protons and neutrons
59 seem to be OK. Isotope production is still problematic. There seems
60 to be too much fission.
62 24 October 2007 - Pekka Kaitaniemi (hadr-incl-V09-00-04)
63 ----------------------------------
64 - Modified INCL to filter out unphysical events containing particles
65 that have more energy than the energy of the projectile. This should
66 fix problem we had with outcoming neutrons (and protons) that have
67 more energy than the projectile particle.
68 - Added G4InclAblaDataFile class that reads data used by INCL/ABLA
69 from datafiles located in $G4ABLADATA. If this environment variable
70 is not correctly set INCL/ABLA returns G4Exception.
71 - Problematic hardcoded data has been removed.
73 16 October 2007 - Pekka Kaitaniemi
74 ------------------------------------------------------
75 - Silenced the rather verbose output. Now nothing should be printed on
77 - Fixed INCL internal random number generator bug that sometimes
78 (rarely) produced random numbers that were greater than 1.0.
79 - Random number seeds are now taken from CLHEP::HepRandom.
80 - Cleaned up some commented code.
81 - Found new NaN bugs in ABLA.
83 13 October 2007 - Pekka Kaitaniemi
84 ------------------------------------------------------
85 - Interface cleanup. G4InclCascadeInterface and
86 G4InclLightIonInterface should be fully operational.
87 - INCL was reverted back to using simple random number generator for
88 test result compatibility (to produce exactly same results as the
89 FORTRAN version does).
90 - Fixes for ABLA evaporation/fission:
91 o Fission barrier problem fixed. Now fission code is called during
93 o Several NaN bugs fixed.
94 o Random seed initialization bug fixed.
95 o Stand-alone INCL/ABLA program (test/standaloneinclabla) mostly
96 works (produces results that are sometimes in good agreement with
97 FORTRAN version and sometimes in not so good agreement). With
98 heavy targets and lots of energy fission is overestimated.
99 o INCL+ABLA interface not yet fully operational. G4 simulation run
102 11 October 2007 - Gabriele Cosmo (hadr-incl-V09-00-01)
103 ------------------------------------------------------
105 o Commented out usage of isnan() and isinf() in assertions.
106 o Replaced usage of M_PI with CLHEP::pi.
107 o Use std namespace for standard mathematical functions.
108 o Casted to double arguments used in std::pow() function.
109 o Commented out initialisation of data in G4InclAblaHardcodedData.cc
110 for Windows; temporary solution to allow for compilation, pending
111 solution of loading of data from file !
113 23 May 2007 - Aatos Heikkinen (hadr-incl-V09-00-00)
114 ---------------------------------------------------
115 - First version of the Liege cascade INCL Model.
