The matrix is not symmetric and has a size of ~1000. I'm solving a triangular system and the result is blocks of bandwidth 2 or 4 (see pic here and here). It is diagonally dominant and I am not sure of the condition number.
What would the best use of preconditioner be? MILU or BLIU? I am pairing this with the Krylov BiCGStab solver.
Thanks.
