TSDiscGradUseGonzalez#

Sets discrete gradient formulation with or without additional conservative terms.

Synopsis#

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

Not Collective

Input Parameters#

  • ts - timestepping context

  • flg - PETSC_TRUE to use the Gonzalez term

Options Database Key#

  • -ts_discgrad_gonzalez - use the Gonzalez term for the discrete gradient formulation

Notes#

Without flg, the discrete gradients timestepper is just backwards Euler.
