DMKSPSetComputeRHS#

set KSP right-hand side evaluation function

Synopsis#

#include "petscksp.h" 
PetscErrorCode DMKSPSetComputeRHS(DM dm, KSPComputeRHSFn *func, void *ctx)

Not Collective

Input Parameters#

  • dm - DM used with a KSP

  • func - right-hand side evaluation function, for calling sequence see KSPComputeRHSFn

  • ctx - context for right-hand side evaluation

Note#

KSPSetComputeRHS() is normally used, but it calls this function internally because the user context is actually associated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or not.

Developer Note#

If DM took a more central role at some later date, this could become the primary method of setting the matrix.
