DMTSSetRHSFunction#

set TS explicit residual evaluation function

Synopsis#

#include "petscts.h" 
PetscErrorCode DMTSSetRHSFunction(DM dm, TSRHSFunction func, void *ctx)

Not Collective

Input Parameters#

  • dm - DM to be used with TS

  • func - RHS function evaluation routine

  • ctx - context for residual evaluation

Note#

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