DMTSSetIFunctionLocal#

set a local implicit function evaluation function. This function is called with local vector containing the local vector information PLUS ghost point information. It should compute a result for all local elements and DM will automatically accumulate the overlapping values.

Synopsis#

#include "petscts.h" 
PetscErrorCode DMTSSetIFunctionLocal(DM dm, PetscErrorCode (*func)(DM, PetscReal, Vec, Vec, Vec, void *), void *ctx)

Logically Collective

Input Parameters#

  • dm - DM to associate callback with

  • func - local function evaluation

  • ctx - context for function evaluation
