RWIND Simulation is a stand-alone program for CFD simulation of wind flow around buildings or any other objects and generating wind loads, i.e. forces acting on these objects. The wind pressures and suctions can be imported as loads into the structural analysis software RFEM or RSTAB.

Buildings are structures surrounded by wind. The flow around them creates specific loads on the surfaces, which are to be used for the design in structural analysis.
Le vent est la seule charge climatique agissant sur toute forme de structure dans tous les pays au monde, contrairement à la neige. Son ampleur varie selon sa localisation géographique. C’est l’une des raisons principales qui justifient aujourd’hui dans les normes, le découpage régional (zone de vent) et la considération de l’altitude, ainsi que la variation des pressions dynamiques en fonction de la hauteur au-dessus du sol pour un site "normal", sans effet de masque.
The fatigue design according to EN 1992-1-1 must be performed for the structural components subjected to large stress ranges and/or many load changes. In this case, the design checks for the concrete and the reinforcement are performed separately. There are two alternative design methods available.
The three types of moment frames (Ordinary, Intermediate, Special) are available in the Steel Design add-on of RFEM 6. The seismic design result according to AISC 341-22 is categorized into two sections: member requirements and connection requirements.
With the Camera Fly Mode view option, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.

There are load generators available for beam structures, creating snow loads according to ASCE/SEI 7-10. The load cases are generated depending on the roof shape. Another generator creates coating loads (ice). You can save recurring load combinations as templates.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
