24 Class
25  Foam::pointConstraint
26 
27 Description
28  Accumulates point constraints through successive applications of the
29  applyConstraint function.
30 
31  After all the constraints have been entered the resulting
32  transformation tensor is returned by the constraintTransformation
33  function.
