Question
How can I import an IFC model into the RWIND Simulation environment?Answer
The stand-alone program RWIND Simulation currently only allows the import of the STL and VTP model geometries. On the other hand, the IFC models can currently only be imported to RWIND Simulation by using the integrated interface in the program RFEM or RSTAB. For this, proceed as follows:
- Create a new RFEM or RSTAB model.
- In General Data, activate the "Enable CAD/BIM Model" option under the Options tab.
Image 01 - Activating CAD/BIM Model Environment - Use the "Import New Model - IFC" function in the Project navigator to import the desired Reference View IFC model under the "CAD/BIM Model" tab.
Image 02 - IFC Import - Model a pseudo-surface without the influence of the wind geometry within the IFC model body.
- Open the "RWIND Simulation - Simulate and Generate Wind Loads" interface under the "Calculation" menu.
- Specify the wind to be applied in the "Wind Load" tab.
- In the "Settings" tab, select the "Export Surrounding Model" and "CAD/BIM Models" options in the "Export to RWIND Simulation" section.
Image 03 - Export of CAD/BIM Model to RWIND Simulation - In the "Load Cases" tab, select the wind direction to be analyzed and open the RWIND Simulation environment using the "Open in RWIND Simulation" function.
- Use the imported IFC model in RWIND Simulation.

Why 3D Models in Structural Design?
Digital trends, such as Building Information Modeling (BIM) or new options for creating realistic visualized models, are based on 3D models. But do 3D models really have an advantage or are we just following a trend? The following presents some arguments for working in 3D models.
The results of the form‑finding process are a new shape and corresponding inner forces. Usual results such as deformations, forces, stresses, and others can be displayed in the RF‑FORM‑FINDING case.
This prestressed shape is available as the initial state for all other load cases and combinations in the structural analysis.
For more ease when defining load cases, the NURBS transformation can be used (Calculation Parameters / Form‑Finding). This feature moves the original surfaces and cables into the position after form‑finding.
By using the grid points of surfaces or the definition nodes of NURBS surfaces, free loads can be situated on selected parts of the structure.
