DMTSSetIFunction
set TS implicit function evaluation function
Synopsis
#include "petscts.h"
PetscErrorCode DMTSSetIFunction(DM dm,TSIFunction func,void *ctx)
Not Collective
Input Arguments
| dm | - DM to be used with TS
|
| func | - function evaluation function, see TSSetIFunction() for calling sequence
|
| ctx | - context for residual evaluation
|
Note
TSSetFunction() 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.
