TSComputeIFunction

Evaluates the DAE residual written in implicit form F(t,X,Xdot)=0

Synopsis

#include "petscts.h"  
PetscErrorCode TSComputeIFunction(TS ts,PetscReal t,Vec X,Vec Xdot,Vec Y)
Collective on TS and Vec

Input Parameters

ts - the TS context
t - current time
X - state vector
Xdot - time derivative of state vector

Output Parameter

Y -right hand side

Note

Most users should not need to explicitly call this routine, as it is used internally within the nonlinear solvers.

If the user did did not write their equations in implicit form, this function recasts them in implicit form.

Keywords

TS, compute
