24 Class
25     Foam::ICCG
27 Description
28     Incomplete Cholesky preconditioned CG solver derived from the general
29     preconditioned CG solver PCG but with the choice of preconditioner
30     pre-selected.
32 Deprecated
33     This solver is present for backward-compatibility and the PCG solver
34     should be used for preference. (deprecated Apr 2008)
