33 // Description:
34 // The process that triggers parameterised simulations if any.
35 //
36 // History:
37 // Feb 98: Parallel geometry sensitivity. MoraDeFreitas.
38 // Oct 97: "Fast" replaces "Parameterisation" in class/method names.
39 // (release B.00 for parameterisation). MoraDeFreitas.
40 // Aug 97: First implementation. Verderi && MoraDeFreitas.
41 // Apr 98: modified for new particle change. H.Kurashige
42 // Oct 06: Move to parallel geometry scheme. M. Verderi
43 // Nov 06: name xxx81 is given for this release. "81" will be
44 // removed @ next maj. rel. so that this process becomes
45 // the standard one.
46 // May 07: remove "81" tags, to migrate to 9.0.
