TSRHSJacobianTest#

Compares the multiply routine provided to the MATSHELL with differencing on the TS given RHS function.

Synopsis#

#include "petscts.h"  
PetscErrorCode TSRHSJacobianTest(TS ts, PetscBool *flg)

Logically Collective

Input Parameter#

  • ts - the time stepping routine

Output Parameter#

  • flg - PETSC_TRUE if the multiply is likely correct

Options Database Key#

  • -ts_rhs_jacobian_test_mult - mat_shell_test_mult_view - run the test at each timestep of the integrator

Note#

This only works for problems defined using TSSetRHSFunction() and Jacobian NOT TSSetIFunction() and Jacobian
