This tutorial is from our online seminar held in March 2013.

This seminar is on multi-point constraints or R-elements (e.g., RBE2 and RBE3) and the CBUSH.

These elegantly formulated elements will be discussed from a theoretical background and then demonstrated through a number of examples.  The goal of this seminar is to provide the Nastran analyst with a comfortable foundation in how these elements can be used accurately and efficiently.  It has been our experience that in the modeling of bolted connections or non-structural discrete masses or just providing a flexible connection between adjacent parts, the right choice of connection element can be very important in the downstream results interpolation.
