Detailed Description

ILU0 BiCGStab.

Author:

Bernard De Cuyper

Version:

1.16

Date:

25/10/2004

Remarks:

Tornado1 Iterative ILU0 Linear Solver

Todo:

omega tracking

 
Purpose:        Bicgstab with IncompleteLU0 preconditioning of a nonsymmetric nxn Linear Solver
                        Used to solve a set of linearized differencial equations,....

                        Some restoration are of the style: A * iNew = iOld
                        iNew could be X, and iOld could be b.
