◆ add_dof_constraints_to_dof_map()

void MAST::KinematicCoupling::add_dof_constraints_to_dof_map ( )

initializes the dof constraint rows in the DofMap object associated with the system.

Definition at line 84 of file kinematic_coupling.cpp.

◆ add_master_and_slave() [1/2]

void MAST::KinematicCoupling::add_master_and_slave	(	const std::set< const libMesh::Node *> &	master,
		const libMesh::Node &	slave,
		bool	constrain_rotations
	)

Constrain the slave node to the specified set of master nodes.

A geometric relation is used to compute the weights for each master dof. If constrain_rotations is true then the rotations of the slave nodes are constrained to those of the master nodes. Otherwise, the constraint acts as a pinned connection.

◆ add_master_and_slave() [2/2]

void MAST::KinematicCoupling::add_master_and_slave	(	const std::vector< std::pair< const libMesh::Node , std::set< const libMesh::Node >>> &	couplings,
		bool	constrain_rotations
	)

provides a vector of the pair of slave and set of master nodes.

◆ get_constraint_rows()

void MAST::KinematicCoupling::get_constraint_rows ( std::vector< std::tuple< libMesh::dof_id_type, libMesh::DofConstraintRow, Real >> & constrs )

Provides the vector of constraints and right-hand-side value pairs to be added to the system.
