Q: How do I determine wind loads on structures of any shape?

The new stand-alone program RWIND Simulation provides you with options for wind simulation and for generating wind loads. These options can be optimally utilized in conjunction with the FEA structural analysis software RFEM or the structural frame analysis software RSTAB.InputThe direct import of models from RFEM or RSTAB allows you to determine the relevant parameters of the wind directions to be analyzed with height-dependent wind profiles on the basis of a wind standard. This results in the corresponding load cases with globally defined parameters.You can also run RWIND Simulation manually without RFEM or RSTAB. Furthermore, it is possible to import the data from STL vector graphics.The import of terrain and buildings of the environment into the simulation is also possible from STL files.By exchanging the data between RFEM or RSTAB and RWIND Simulation, you can easily use the wind analysis results as load cases in the usual RFEM or RSTAB work environment.Features of RWIND Simulation3D incompressible wind flow analysis with OpenFoam solversDirect model import of RFEM, RSTAB, or STL filesSimple model changes using Drag and Drop and graphical adjustment assistanceAutomatic corrections of the model topology with shrink wrap networksOption to add objects from the environment (buildings, terrain ...)Height-dependent velocity profiles according to the standardK-epsilon and K-omega turbulence modelsAutomatic mesh generating adjusted to the selected depth of detailParallel calculation with optimal utilization of the capacity of multicore computersResults in just minutes for low-resolution simulations (up to 1 million cells)Results within a few hours for simulations with medium/high resolution (1‑10 million cells)Graphical display of results on the Clipper/Slicer planes (scalar and vector fields)Graphical display of streamlines and streamline animation

How do I determine wind loads on structures of any shape?

Answer

The new stand-alone program RWIND Simulation provides you with options for wind simulation and for generating wind loads. These options can be optimally utilized in conjunction with the FEA structural analysis software RFEM or the structural frame analysis software RSTAB.

Input

The direct import of models from RFEM or RSTAB allows you to determine the relevant parameters of the wind directions to be analyzed with height-dependent wind profiles on the basis of a wind standard. This results in the corresponding load cases with globally defined parameters.

You can also run RWIND Simulation manually without RFEM or RSTAB. Furthermore, it is possible to import the data from STL vector graphics.

The import of terrain and buildings of the environment into the simulation is also possible from STL files.

By exchanging the data between RFEM or RSTAB and RWIND Simulation, you can easily use the wind analysis results as load cases in the usual RFEM or RSTAB work environment.
