Tells the system to do an in-place incomplete factorization. Collective on PC
Synopsis
int PCILUSetUseInPlace(PC pc)
Input Parameters
pc -the preconditioner context
Options Database Key
-pc_ilu_in_place -Activates in-place factorization
Note
PCILUSetUseInPlace() is intended for use with matrix-free variants
ofKrylov methods, or when a different matrices are employed for the
linearsystem and preconditioner. Do NOT use this option if the linear
systemmatrix also serves as the preconditioning matrix, since the
factoredmatrix would then overwrite the original matrix.
