TSSetRHSFunction

Sets the routine for evaluating the function, F(t,u), where U_t = F(t,u).

Synopsis

int TSSetRHSFunction(TS ts,int (*f)(TS,double,Vec,Vec,void*),void *ctx)
Collective on TS

Input Parameters

ts - the TS context obtained from TSCreate()
f - routine for evaluating the right-hand-side function
ctx - [optional] user-defined context for private data for the function evaluation routine (may be PETSC_NULL)

Calling sequence of func

    func (TS ts,double t,Vec u,Vec F,void *ctx);

t - current timestep
u - input vector
F - function vector
ctx - [optional] user-defined function context

Important

The user MUST call either this routine or TSSetRHSMatrix().
