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.

Keywords
