SEADYN87 User's Manual.

Abstract

This document describes the input structure and general use of the nonlinear cable dynamics computer model SEADYN. This program performs static, time and frequency domain dynamic, and model analyses for arbitrarily configured cable-truss structures. Significant capabilities include: multi-materials, bottom interaction, nonlinear material properties, material damping, payout reel-in, strumming effects, spatially varying current fields, imposed motions, and random wave loading. Results can be saved and reused during the current execution or at a later date. A free-field input reader is used. This user manual describes the program input format and external file requirements, and briefly discusses use of the program. Example inputs are presented. Computer program; Underwater cable dynamics; Finite-element analysis; Nonlinear mooring analysis; Mooring cables; Truss structures; Catenaries; Load distribution; Dynamic response; Hydrodynamic drag.
