# DMPlexGenerateRegister

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
