TSComputeRHSJacobianConstant#
Reuses a Jacobian that is time-independent.
Synopsis#
#include "petscts.h"
PetscErrorCode TSComputeRHSJacobianConstant(TS ts, PetscReal t, Vec U, Mat A, Mat B, void *ctx)
Collective
Input Parameters#
ts - time stepping context
t - time at which to evaluate
U - state at which to evaluate
ctx - context
Output Parameters#
A - pointer to operator
B - pointer to preconditioning matrix
Note#
This function is intended to be passed to TSSetRHSJacobian() to evaluate the Jacobian for linear time-independent problems.
