DIC / DILU: diagonal incomplete-Cholesky (symmetric) and incomplete-LU (asymmetric) FDIC: faster diagonal incomplete-Cholesky (DIC with caching, symmetric) diagonal: diagonal preconditioning. GAMG: geometric-algebraic multi-grid. I tested RapidCFD for some test cases, where the Preconditioners are always AINV, instead of DILU and DIC from openfoam. Do you have any plan to include DILCU or DIC preconditioners to RapidCFD? Some of the tutorial cases from openfoam are not producing the exact results, when we compare the solution generated by openfoam and RapidCFD.
