1 Introduction

This text outlines the benefits of using CFD (Computational Fluid Dynamics), particularly in contrast to conventional wind tunnel testing.

Validating CFD simulations with experimental data enhances accuracy by comparing simulation outcomes with real-world conditions. This process identifies discrepancies, allowing adjustments to enhance model reliability. Ultimately, it builds confidence in the simulation's ability to predict wind load scenarios.

This paper is focused on the specific aspects of designing membrane structures that have specific requirements, such as form-finding and cutting pattern generation. An integral part of the design of these structures is the process of finding suitable prestressed shapes and generating cutting patterns. The text briefly describes two basic processes in the design of membrane structures. The physical principles are explained and the individual theses illustrated by examples.

The results of solid stresses can be displayed as colored 3D points in the finite elements.

The stand-alone program RWIND 3 takes care of fresh air. It is used for the numerical simulation of wind flow and is available in a Basic as well as a Pro version. What additional features does RWIND Pro offer you? It allows for the calculation of transient incompressible turbulent wind flows (in addition to the stationary ones in RWIND Basic). But that's not all. Intrested in learning more? Find out more here:

In RWIND Simulation, it is possible to divide the model in different zones. This allows for different surface roughness to be assigned to the zones. In addition, local results can be better evaluated.
