24 Class
25     Foam::BICCG
27 Description
28     Diagonal incomplete LU preconditioned BiCG solver derived from the general
29     preconditioned BiCG solver PBiCG but with the choice of preconditioner
30     pre-selected.
32 Deprecated
33     This solver is present for backward-compatibility and the PBiCG solver
34     should be used instead. (deprecated Apr 2008)
