set a local Jacobian evaluation function

Synopsis#

#include "petscsnes.h" 
PetscErrorCode DMSNESSetJacobianLocal(DM dm, PetscErrorCode (*func)(DM dm, Vec X, Mat J, Mat Jp, void *ctx), void *ctx)

Logically Collective

Input Parameters#

  • dm - DM to associate callback with

  • func - local Jacobian evaluation

  • ctx - optional context for local Jacobian evaluation

Calling sequence of func#

  • dm - the DM context

  • X - current solution vector (ghosted or not?)

  • J - the Jacobian

  • Jp - approximate Jacobian used to compute the preconditioner, often J

  • ctx - a user provided context
