DMTSSetSolutionFunction#
set TS solution evaluation function
Synopsis#
#include "petscts.h"
PetscErrorCode DMTSSetSolutionFunction(DM dm, TSSolutionFunction func, void *ctx)
Not Collective
Input Parameters#
dm - DM to be used with TS
func - solution function evaluation routine
ctx - context for solution evaluation
Calling sequence of f#
PetscErrorCode f(TS ts,PetscReal t,Vec u,void *ctx);
ts - timestep context
t - current timestep
u - output vector
ctx - [optional] user-defined function context
Note#
TSSetSolutionFunction() 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.
