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