A unique project called "Oxigeno" is currently under construction in San Francisco de Heredia, San José, Costa Rica. The recreational and commercial space, which measures almost 1,345,489 ft², provides visitors with a relaxing shopping atmosphere in harmony with nature. For this purpose, approximately 200 trees were planted on the site. The "Main Food Court" is covered with a 17,222 ft² ETFE cushion as a roof, currently the biggest in the world.
z3rch, a customer of Dlubal Software, used RFEM and RF-FORM-FINDING for the form-finding and calculation of the structure, including the cable-net structure and the membranes.

This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
RWIND 2 is a program for generating wind loads based on CFD (Computational Fluid Dynamics). The wind flow numerical simulation is generated around any building, including irregular or unique geometry types, to determine the wind loads on surfaces and members. RWIND 2 can be integrated with RFEM/RSTAB for the structural analysis and design or as a stand-alone application.
This article describes the development of the Parametric FEM Toolbox and some of the possible workflows with this new tool.

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

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).
Display extended strains of members, surfaces, and solids (for example, the important principal strains, equivalent total strains, and so on) in the Project Navigator - Results in RFEM as well as in Table 4.0.
For example, you can display governing plastic strains when performing the plastic design of connections with surface elements.
RFEM and RSTAB models can be saved as 3D glTF models (*.glb and *.glTF formats). View the models in 3D in detail with a 3D viewer from Google or Babylon. Take your VR glasses, such as Oculus, to "walk" through the structure.
You can integrate the 3D glTF models into your own websites using JavaScript according to the instructions (as on the Dlubal website Models to Download): "Easily display interactive 3D models on the web & in AR" .
Does RFEM 5 include a surface contact?
Can I display node coordinates in my model?
Can I use SHAPE-THIN 9 in combination with RSTAB 8?
Has the RF-TOWER add-on module for RFEM 5 already been added to RFEM 6?
RFEM calculates more slowly on my new computer than on the old one. What might be the cause, and how can I change it?
Where can I find my customer number in RFEM or RSTAB?
