Analysis & Design Software for Shipbuilding

Structural Engineering Software for Shipbuilding

RFEM and RSTAB are suited very well for structural analysis of ships or ship components (e.g. ship crane, mast, hull, pulley). It is also possible to consider nonlinearities such as cables and to perform dynamic, stability, and buckling analyses.

Moreover, it is also possible to model and design shipping containers in RFEM.

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

Analysis & Design of Frame/Beam/Truss Structures

Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame and truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural engineers.

RFEM Model of Sailing Ship 'Alexander von Humboldt II'

The sailing ship 'Alexander von Humboldt II' began its service in October 2011 and has been conquering the seas ever since.

The ship, operated by German Sail Training Foundation (DSST), is a barque rigged with three masts. The masts and the hull consist of steel.

In addition to typical FE calculations of highly stressed systems such as mooring, anchor and davit units, the rigging forces were analyzed in detail.

Form-Finding in RFEM

The RF-FORM-FINDING add-on module determines equilibrium shapes of membrane and cable elements in RFEM. In this calculation process, the program searches for such a geometric position in which the surface stress/prestress of membranes and cables is in equilibrium with natural and geometric boundary conditions. This process is called form-finding (hereinafter referred to as FF). The FF calculation can be activated in RFEM globally in the "General Data" of a model, "Options" tab. After selecting the corresponding option, a new load case or a calculation process called RF-FORM FINDING is created in RFEM. An additional FF parameter is available for defining surface stress and prestress when entering cables and membranes. By activating the FF option, the program always starts the form-finding process before the pure structural calculation of internal forces, deformation, eigenvalues, etc., and generates a corresponding prestressed model for further analysis.

Cable on Pulleys

In RFEM, you have the option to create and analyze cables using sheaves. For this, use the ‘Cable on Pulleys’ member type. It is ideal for pulley systems, where the longitudinal forces are transferred via sheaves.
