Depending on stiffness, mass, and damping, structures react differently to wind action. A basic distinction is made between buildings that are prone to vibration and those that are not vibration-prone.

For design objects, you can optionally display sags or extreme results.

The results of solid stresses can be displayed as colored 3D points in the finite elements.

In RWIND Simulation, it is possible to divide the model in different zones. This allows for different surface roughness to be assigned to the zones. In addition, local results can be better evaluated.

The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (for example, trusses and membrane structures).
