// 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
