Adds a grid generator to DMPlex

Synopsis

#include "petscdmplex.h"   
PetscErrorCode  DMPlexGenerateRegister(const char sname[],PetscErrorCode (*fnc)(DM, PetscBool,DM*), PetscErrorCode (*rfnc)(DM, double*,DM*),PetscInt dim)
Not Collective

Input Parameters

name_solver - name of a new user-defined grid generator
fnc - generator function
rfnc - refinement function
dim - dimension of boundary of domain

Notes

DMPlexGenerateRegister() may be called multiple times to add several user-defined solvers.

Sample usage

   DMPlexGenerateRegister("my_generator",MyGeneratorCreate,MyGeneratorRefiner,dim);

Then, your generator can be chosen with the procedural interface via

    DMPlexGenerate(dm,"my_generator",...)
or at runtime via the option
    -dm_plex_generator my_generator
