Hi, I have a complex system of equations and I use PETSc to solve the system. I also use MKL to create the preconditioner using ILU. The ILU preconditioner is created only on the real part of the coefficient matrix and is stored in CSR format with the data type of double precision. I wanted to ask if it is possible to use this preconditioner and pass it to PETSc in CSR format? Can it be used with PETSc complex solver although the preconditioner is in double precision format?
