Member Function Documentation

void sfem::mesh::InternalConstraintDefinition::createConstraintMatrix	(	const InternalConstraintDefinition &	additional_constraints,
		TSparseMatrix &	conre_matrix,
		TSparseVector &	offset_slave_dofs
	)			const

creates the constraint relations in algebraic form, i.e. u_global = D*u_master+b The number of rows corresponds to the number of available (global) dofs, the number of columns is the number of active (master) dofs.

Parameters:

	additional_constraints	may be empty. It may contain additional consraint definitions to be added to conre-relations
	conre_matrix	will contain the matrix D
	offset_slave_dofs	will contain teh vector b

Member Data Documentation

TypeCoeffPairListVector sfem::mesh::InternalConstraintDefinition::constraint_coeffs [protected]

the coefficients of the constraint matrix (each row is one constraint; indices refer to the global DOF id) one reads: sum_i coefficient_i*dof_i = rhs
