Public Member Functions

	Apply the BC to the system using Lagrangian multiplier method. It directly modifies the global stiffness matrix thus requires a mutex. Other global matrices shall also be modified to ensure the solution is trivial on target DoFs.

int	initialize (const shared_ptr< DomainBase > &) override

int	process (const shared_ptr< DomainBase > &) override
	Apply the BC to the system using penalty method. It effectively adds a diagonal matrix to the global stiffness matrix.
