DMTSGetForcingFunction
get TS forcing function evaluation function
Synopsis
#include "petscts.h"
PetscErrorCode DMTSGetForcingFunction(DM dm,TSForcingFunction *f,void **ctx)
Not Collective
Input Argument
dm -DM to be used with TS
Output Arguments
| f | - forcing function evaluation function; see TSForcingFunction for details
|
| ctx | - context for solution evaluation
|
Note
TSSetForcingFunction() 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.
