Is it also possible to simulate an external steel structure in RWIND Simulation?


Yes, the RWIND Simulation program is generally designed and can implement any model of RFEM or RSTAB.

Figure 03 - RFEM Model

For a steel structure consisting of pure member elements, the program creates a coherent, voluminous envelope of the member surfaces for the numerical wind tunnel. The result of this modeling for the simulation depends on the available cross-sections and the mesh settings. Due to the wind current, corresponding surface pressures result on this surface layer.

Figure 02 - Surface Pressure on OpenFOAM Mesh

After having calculated the wind flow, the program sums the surface pressures of the member units and returns a corresponding equivalent load (single, uniform, or trapezoidal) for each member axis.

These loads are applied in RFEM or RSTAB for the further calculation of internal forces.
