TSComputeI2Function
Evaluates the DAE residual written in implicit form F(t,U,U_t,U_tt) = 0
Synopsis
#include "petscts.h"
PetscErrorCode TSComputeI2Function(TS ts,PetscReal t,Vec U,Vec V,Vec A,Vec F)
Collective on TS and Vec
Input Parameters
 ts   the TS context

 t   current time

 U   state vector

 V   time derivative of state vector (U_t)

 A   second time derivative of state vector (U_tt)

Output Parameter
F the residual vector
Note
Most users should not need to explicitly call this routine, as it
is used internally within the nonlinear solvers.
