Software for CFD Wind Simulations & Wind Load Generation

FEM Analysis and Design of Structures

The structural analysis program RFEM is the basis of a modular software system. The main program 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

The structural frame analysis and design program RSTAB contains a similar range of functions as RFEM, with special attention to frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.

CFD Simulation of Wind Flows

RWIND Simulation is a program for numerical simulations of wind flows around buildings or any other objects and generating wind loads, i.e. forces acting on these objects.

RWIND Simulation | Canopy Roofs According to Eurocode 1 in Wind Channel (Case A)

Length 0:22 min

This video shows the realistic "Airflow over canopy roofs" in RWIND Simulation. RWIND Simulation can generate the exact wind flow for the first case in EN 1991-1-4 Section 7.3 Figure 7.15 (empty, free-standing canopy (φ = 0)) and export the resulting loads to RFEM.
