- Create a new RFEM or RSTAB model.
- In General Data, activate the "Enable CAD/BIM Model" option under the Options tab.
- 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.
- 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.
- 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.
Question
How can I import an IFC model into the RWIND Simulation environment?
In addition to JavaScript, the Python high-level functions are also available in the console. Using the Python option, the console also provides you with the Python HLF functions known from the WebService function catalog for further use in the object properties dialog box for in-app scripting.
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
If you have experimentally determined surface pressures available for a model, you can apply them to a structural model in RFEM 6, process them in RWIND 2, and use them as wind loads in the structural analysis of RFEM 6.
You can find out how to apply the experimentally determined values in this Knowledge Base article: Static Analysis with Wind Loads from Experimentally Measured Pressures Using RWIND 2 and RFEM 6
In RFEM 6 and RSTAB 9, you can export line graphics to the SVG format (vector graphics).
SVG stands for Scalable Vector Graphics and is an XML-based file format for displaying two-dimensional vector graphics. These vector graphics can be scaled without loss. It is possible to edit the SVG files using text editors, embed them on websites, and open them in the usual browsers.
