Creative Systems is the originator of GHS, the world-famous PC-based simulator of vessels in fluids and fluids in vessels - for ships, yachts, docks, drilling platforms, buoys, tanks, etc. - answering such questions as:
  • How deep and at what attitude will it float?
  • How much load will it carry?
  • When will it capsize?
  • Will it survive if damaged?
  • In addition, GHS calculates tank characteristics: volume and surface properties of any tank, pool, basin, etc. Also does longitudinal strength: shear and bending moments, stress and deflection due to weight and buoyancy forces. Includes ground reaction: buoyancy arising from points of ground contact.
    Rhino3D is a versatile 3-D modeler that can create, edit, analyze, document, render, animate, and translate NURBS* curves, surfaces, and solids, point clouds, and polygon meshes. There are no limits on complexity, degree, or size beyond those of your hardware.
    One important reason for using Rhino is the extended interface to communicate with other CAD packages.
    Femap (Finite Element Modeling And Postprocessing) is an engineering analysis program sold by Siemens PLM Software that is used to build finite element models of complex engineering problems ("pre-processing") and view solution results ("post-processing"). It provides CAD import, modeling and meshing tools to create a finite element model, as well as postprocessing functionality that allows mechanical engineers to interpret analysis results. The finite element method allows engineers to virtually model components, assemblies, or systems to determine behavior under a given set of boundary conditions, and is typically used in the design process to reduce costly prototyping and testing, evaluate differing designs and materials, and for structural optimization to reduce weight.
    Femap is used by engineering organizations and consultants to model complex products, systems and processes including satellites, aircraft, defense electronics, heavy construction equipment, lift cranes, marine vessels and process equipment.
    In addition NX Nastran is used as solver
