Detailed Description
many of the functions in this file amount to extracting element indices from an mesh_t like
| mfem::Geometry | mfem element id | tri id | quad id |
|---|---|---|---|
| Triangle | 0 | 0 | |
| Triangle | 1 | 1 | |
| Square | 2 | 0 | |
| Triangle | 3 | 2 | |
| Square | 4 | 1 | |
| Square | 5 | 2 | |
| Square | 6 | 3 |
and then evaluating a predicate function to decide whether that element gets added to a given Domain.
