Hello All,

I am curious as to how the diagonal preconditioners work in openfoam. I know that a DIC preconditioner is a Simplified diagonal-based incomplete Cholesky preconditioner for symmetric matrices. I know that the diagonal is saved for later use, but is it just a diagonal matrix preconditioner? what is a good source covering these simplified diagonal preconditioners?
