dm | - The mesh object | |
isEssential | - Flag for an essential (Dirichlet) condition, as opposed to a natural (Neumann) condition | |
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 |
