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"
