TSRHSSplitSetRHSFunction#

Set the split right-hand-side functions.

Synopsis#

#include "petscts.h"  
PetscErrorCode TSRHSSplitSetRHSFunction(TS ts, const char splitname[], Vec r, TSRHSFunction rhsfunc, void *ctx)

Logically Collective

Input Parameters#

ts - the TS context obtained from TSCreate()
splitname - name of this split
r - vector to hold the residual (or NULL to have it created internally)
rhsfunc - the RHS function evaluation routine
ctx - user-defined context for private data for the split function evaluation routine (may be NULL)

Calling sequence of `rhsfun`#

PetscErrorCode rhsfunc(TS ts, PetscReal t, Vec u, Vec f,ctx)

ts - the TS context obtained from TSCreate()
t - time at step/stage being solved
u - state vector
f - function vector
ctx - [optional] user-defined context for matrix evaluation routine (may be NULL)
