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