TSSetRHSFunction#
Sets the routine for evaluating the function, where U_t = G(t,u).
Synopsis#
#include "petscts.h"
PetscErrorCode TSSetRHSFunction(TS ts, Vec r, PetscErrorCode (*f)(TS, PetscReal, Vec, Vec, void *), void *ctx)
Logically Collective
Input Parameters#
Calling sequence of f#
PetscErrorCode f(TS ts,PetscReal t,Vec u,Vec F,void *ctx);
ts - timestep context
t - current timestep
u - input vector
F - function vector
ctx - [optional] user-defined function context
Note#
You must call this function or TSSetIFunction()
to define your ODE. You cannot use this function when solving a DAE.
