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