TSSetI2Function

Set the function to compute F(t,U,U_t,U_tt) where F = 0 is the DAE to be solved.

Synopsis

#include "petscts.h"  
PetscErrorCode TSSetI2Function(TS ts, Vec F, TSI2FunctionFn *fun, void *ctx)

Logically Collective

Input Parameters

• ts - the TS context obtained from TSCreate()

• F - vector to hold the residual (or NULL to have it created internally)

• fun - the function evaluation routine

• ctx - user-defined context for private data for the function evaluation routine (may be NULL)
