Detailed Description
LagrangeSP\_FE is a subclass of FE\_Element used to enforce a single point constraint. It does this by adding to the tangent and the residual:
at the locations corresponding to the constrained degree-of-freedom specified by the SP\_Constraint and the lagrange multiplier degree-of-freedom introduced by the LagrangeConstraintHandler for this constraint, where
is the specified value of the constraint and
the current trial displacement at the node corresponding to the constraint.\
