Question

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

Answer

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

Input
The direct adoption of models from RFEM or RSTAB makes it possible to determine 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.

The RWIND Simulation can also be run manually if there is no RFEM or RSTAB. For this reason, the data can be imported from STL vector graphics.

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

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

Services of RWIND Simulation
  • 3D incompressible wind flow analysis with OpenFoam solvers
  • Direct model import of RFEM or RSTAB or STL files
  • Simple model changes using Drag and Drop and graphical adjustment assistance
  • Automatic corrections of the model topology with shrink wrap networks
  • Option to add objects from the environment (buildings, terrain, ...)
  • Height-dependent velocity profiles according to the standard
  • K-epsilon and K-omega turbulence models
  • Automatic mesh generating adjusted to the selected depth of detail
  • Parallel calculation with optimal utilization of the capacity of multicore computers
  • Results 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 representation of streamlines as well as streamline animation
