inlinestaticconstexprinherited

If internal Dirichlet contraints are enabled Enables / disables internal (non-boundary) Dirichlet constraints. If this is overloaded to return true, the assembler calls problem.hasInternalDirichletConstraint(element, scv). This means you have to implement the following member function.

bool hasInternalDirichletConstraint(const Element& element, const SubControlVolume& scv) const;

which returns a bool signifying whether the dof associated with the element/scv pair is contraint. If true is returned for a dof, the assembler calls problem.internalDiririchlet(element, scv). This means you have to additionally implement the following member function
