DMRegister

Adds a new DM component implementation

#include "petscdm.h"          
#include "petscdmlabel.h"     
PetscErrorCode  DMRegister(const char sname[],PetscErrorCode (*function)(DM))

Not Collective

	name	- The name of a new user-defined creation routine
	create_func	- The creation routine itself

DMRegister() may be called multiple times to add several user-defined DMs

    DMRegister("my_da", MyDMCreate);

Then, your DM type can be chosen with the procedural interface via

    DMCreate(MPI_Comm, DM *);
    DMSetType(DM,"my_da");

or at runtime via the option

    -da_type my_da

DM, register
