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


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

By directly importing models from RFEM or RSTAB , you can define 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.

Without RFEM or RSTAB, RWIND Simulation can be run manually. For this, 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 familiar 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 aids
  • Automatic corrections of the model topology with shrink wrap interconnections
  • 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 meshing adjusted to the selected depth of detail
  • Parallel calculation with optimal utilization of the performance 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
