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 minimal clearance between the slave node (N1) and the projected node (P) in the direction given by the property.
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.
