TSSetIFunction#
Set the function to compute F(t,U,U_t) where F() = 0 is the DAE to be solved.
Synopsis#
#include "petscts.h"
PetscErrorCode TSSetIFunction(TS ts, Vec r, TSIFunctionFn *f, void *ctx)
Logically Collective
Input Parameters#
Note#
The user MUST call either this routine or TSSetRHSFunction()
to define the ODE. When solving DAEs you must use this function.
