| dm | - The mesh object | |
| bd | - The BC number |
| type | - The type of condition, e.g. DM_BC_ESSENTIAL_ANALYTIC/DM_BC_ESSENTIAL_FIELD (Dirichlet), or DM_BC_NATURAL (Neumann) | |
| name | - The BC name | |
| labelname | - The label defining constrained points | |
| field | - The field to constrain | |
| numcomps | - The number of constrained field components | |
| comps | - An array of constrained component numbers | |
| bcFunc | - A pointwise function giving boundary values | |
| numids | - The number of DMLabel ids for constrained points | |
| ids | - An array of ids for constrained points | |
| ctx | - An optional user context for bcFunc |
| -bc_<boundary name> <num> | - Overrides the boundary ids | |
| -bc_<boundary name>_comp <num> | - Overrides the boundary components |
