This manual presents the theoretical background material for the SEADYN cable, truss, and mooring program. SEADYN uses the finite element method for modeling the cables, trusses, and mooring lines. Two elements are treated: the one-dimensional Simplex (truss) element and a bottom-limited catenary. Lumped parameter concepts are used in treating buoys, anchors, floats, etc. Rigid body models are used for ships, platforms, mooring buoys, etc. A cartesian 3-D geometric space is used through-out. Besides describing the element and body equations for submerged responses with large displacements, this manual discusses the various static and dynamic solution methods employed. (Author)
