| dm | - The DM object |
| per | - Whether the DM is periodic or not | |
| maxCell | - Over distances greater than this, we can assume a point has crossed over to another sheet, when trying to localize cell coordinates | |
| L | - If we assume the mesh is a torus, this is the length of each coordinate | |
| bd | - This describes the type of periodicity in each topological dimension |
