User defined neumann 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 gathers these values at the bc mask locations into a compact flux vector and applies the weak neumann contribution. More...
