  • RWINd Simulation

    Software for Wind Simulation & Wind Load Generation

    RWIND Simulation is a stand-alone program for numerical simulations of wind flows (digital wind tunnel) around buildings or any other objects by means of CFD simulation (Computational fluid dynamics).

    The wind simulation can be performed for simple or complex structures. The generated wind loads acting on these objects can be imported to RFEM and RSTAB.

    RWIND Simulation

  • Realized with structural analysis software RSTAB:

    Structural Frame Analysis Software RSTAB

    The structural analysis program RSTAB for design and analysis of space frame structures provides a solution for demanding structural engineers. The software meets requirements of modern civil engineering and reflects the current state of the technology.

New Programs for Cold-Formed Sections

SHAPE-THIN 9 | RF-/STEEL Cold-Formed Sections

The SHAPE‑THIN 9 stand-alone program and the RF‑/STEEL Cold‑Formed Sections add-on module allow you to design general cold-formed sections.

New Software: RWIND Simulation

Wind Simulation (Digital Wind Tunnel) and Wind Load Generation for Structural FEA Software RFEM or RSTAB

RWIND Simulation is a stand-alone program for numerical simulations of wind flow around structures of any shape.

RFEM

RFEM

Structural FEA engineering software RFEM allows easy and effective modeling as well as structural analysis and design of general 2D and 3D structures consisting of member, plate, wall, shell, solid, and contact elements.

RSTAB

RSTAB

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