Q: What does the message *** FATAL ERROR: Nodes Are Not Connected to Rest mean?

A: It means that you are trying to analyze at least two, independent structures (tubulars in golden colour below). In MOSES the subset of the model you are trying to solve must be connected. The premise is that most times a jacket is being transported.

This error normally occurs when one is trying to transport more than one piece of cargo on a barge. To solve this problem one can either make each piece of cargo a separate piece and solve them one at a time, or connect the two pieces with a dummy beam. Many of these details are taken care of automatically with the Automated Installation tools. To see which elements are not connected, take the list of nodes that come with this error message, and create a selection criterion. Use the criterion to show a picture of the structure: &picture iso -ends :list -color selected.
