This model demonstrates the stability analysis of a tilting cube using a stepwise load increment. The method helps accurately identify buckling loads and the associated load factors. A gradual increase of the loads allows analyzing the course of stability up to the critical load. Ideal for studying the behavior of this geometric body under varying load conditions.

Modeling a Kármán vortex street in RWIND
Validating CFD simulations with experimental data enhances accuracy by comparing simulation outcomes with real-world conditions. This process identifies discrepancies, allowing adjustments to enhance model reliability. Ultimately, it builds confidence in the simulation's ability to predict wind load scenarios.
In RFEM 6 it is possible to save selected objects (as well as whole structures) as blocks and reuse them in other models. Three types of blocks can be distinguished: non-parameterized, parameterized, and dynamic blocks (via JavaScript). This article will focus on the first block type (non-parameterized).
This article describes how to create a user-defined antenna bracket to be used in RF-/TOWER Equipment.
After generating the effective lengths, the results are displayed in clearly arranged tables. You can modify the effective lengths manually there.
The Export function transfers the effective lengths to the RF-/TOWER Design add-on module for further calculation. The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
Finally, it is possible to export the generated model to RFEM/RSTAB with a single mouse click.
The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
The results are displayed in clearly arranged module windows. In addition to the design data, the results include all design-relevant parameters. A parts list is generated automatically during the calculation.
The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
When performing the design of tension, compression, bending, and shear loading, the module compares the design values of the maximum load capacity to the design values of the actions. If the components are subjected to both bending and compression, the program performs an interaction. You can determine the factors according to Method 1 (Annex A) or Method 2 (Annex B).
The flexural buckling design requires neither the slenderness nor the elastic critical buckling load of the governing buckling case. The module automatically calculates all required factors for the bending stress design value. RF-/TOWER Design determines the effective critical moment for lateral-torsional buckling for each member on every x-location of the cross-section.
