Analysis & Design Software for Shipbuilding

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.

  1. 1 - General Data

    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.

  2. Cable on Pulleys

    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.
