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 fun#

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