Dear all, I would like to test some ideas of mine over the CG method with incomplete cholesky preconditioner with a drop tolerance. I checked the Hypre manual for the preconditioner generation, however there is not a direct IC preconditioner but and ILUT which results in an unsymmetric preconditioner, is it wise to use this as a preconditioner for CG in PETSc?
Best regards, Umut
