DMTSSetRHSFunction
set TS explicit residual evaluation function
Synopsis
#include "petscts.h"
PetscErrorCode DMTSSetRHSFunction(DM dm,TSRHSFunction func,void *ctx)
Not Collective
Input Arguments
| dm | - DM to be used with TS
|
| func | - RHS function evaluation function, see TSSetRHSFunction() for calling sequence
|
| ctx | - context for residual evaluation
|
Note
TSSetRSHFunction() 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.
