Preconditioner for BiCSTAB
Hi, I´m working with FEM to do the spatial discretization of the Navier-Stokes equations, and fractional step for pressure-velocity coupling. In order to use BiCGSTAB solver, which preconditioner is recomended? Is there any precond that requires no ILU-type factorization? TIA

Re: Preconditioner for BiCSTAB
I have used simple Jacobi(J) and Gausse-Seidel(GS) preconditioners and get good results with very low computational cost.
