logical | strong = .true. |
| Wether the bc is strongly enforced. Essentially valid for all Dirichlet types of bcs. These need to be masked out for solvers etc, so that values are not affected. Mixed bcs are, by convention, weak.
|
|
logical | updated = .false. |
| Indicates wether the bc has been updated, for those BCs that need additional computations.

- The condition is imposed weekly by adding an appropriate source term to the right-hand-side.
