field_dirichlet::field_dirichlet_t Type Referenceabstract

User defined dirichlet condition, for which the user can work with an entire field. The type stores a separate dummy field field_bc, which is passed to the user routine and can be populated with arbitrary values. The boundary condition then copy-pastes these values to the actual solution field using the mask of the boundary condition. So, in the end, only the relevant boundary values are updated. More...

Detailed Description

Note
Would be neat to add another class that contains all three dirichlet bcs for the velocity, this bc would then implement apply_vector.
