Can I also use the wind load generator for open buildings?

Answer

With the load generator, it is currently not possible to generate the loads for open buildings. You could create the loads for a closed hall and then manually fill in the missing loads.

For canopy roof structures, there are different standard-based assumptions, which have not yet been covered by the load generator. To apply the wind load to a free-standing roof, an interesting technical article is already available on our website.


It is also possible to generate the wind load for any building geometry with the new stand-alone program RWIND Simulation. This provides you with the possibilities for wind simulations.
and for generating wind loads. In conjunction with the structural FEA software RFEM or the structural frame analysis software RSTAB.

Input
The direct import of models from RFEM or RSTAB allows you to define the relevant parameters for the analyzed wind directions with the height-dependent wind profiles, based on the wind standard. This results in the corresponding load cases with globally defined parameters.

Without RFEM or RSTAB, RWIND Simulation can also be run manually. Furthermore, you can import the data from the STL vector graphics.

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

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

Features 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 & 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)
Graphically display of results on the Clipper/Slicer planes (scalar and vector fields)
Graphical display of streamlines and streamline animation
