TSComputeIJacobianP#

Runs the user-defined IJacobianP function.

Synopsis#

#include <petscts.h>  
PetscErrorCode TSComputeIJacobianP(TS ts, PetscReal t, Vec U, Vec Udot, PetscReal shift, Mat Amat, PetscBool imex)

Collective

Input Parameters#

  • ts - the TS context

  • t - current timestep

  • U - state vector

  • Udot - time derivative of state vector

  • shift - shift to apply, see note below

  • imex - flag indicates if the method is IMEX so that the RHSJacobianP should be kept separate

Output Parameter#

  • Amat - Jacobian matrix
