The Grout variant of ILU preconditioner developed recently is an attractive and effective preconditioner over the conventional row-based ILU preconditioned This paper explores dropping strategy for fill-in to improve the robustness of ILUC. This paper shows how to compensate a diagonal entry of matrix influenced by dropping. The performances of diagonal-compensated ILUC preconditioner are compared with the ILUT, ILUC decomposition on a set of problems. Results of numerical experiments show that diagonal-compensated ILUC preconditioner outperforms well.
