Q: How can I model a fender attached to a quay?
REV 7.00

A: First, you need to obtain the force-deflection properties of the fender, normally provided by the fender supplier. Then, use the -X_PY option to define these properties to MOSES. You want to specify a generalized spring here (GSPR), so you do not worry about the weight per length, diameter or Young's Modulus. Since you are defining springs in series, select a relatively stiff spring constant for the GSPR. Also, use a sense of COMPRESSION for the GSPR, and be sure to define this in the global system.  There is a sample that shows this in the “how to” section of the samples directory.
