Mesh visualization:
The relations are obtains in the following way:
- Compute the projection of the slave node (N1) on the
surface defined by n-1 master nodes.
- Interpolate the displacement of the projected point (P)
using the shape function of the face defined by the master nodes.
- Impose a relative displacement of master nodes and projected point
(P) to be null in the direction given by the property (or in
the direction of the projection if the property does not contain any
direction information).
The projected point (P) is a conceptual point,
that means it is never created. The displacement of this point is always
expressed in terms of displacement of the master nodes through
interpolation.
