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 functions of the face defined by the master nodes.
- Link the translations normal to the direction given by the property (or direction ) according to rigid body equations.
- Impose a minimum clearance between the slave node (N1) and the projected point (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.
