The RFEM program allows for the input and analysis of general plate, shell, and member structures. The program also allows you to create combined structures as well as to model solid and contact elements.

The results of solid stresses can be displayed as colored 3D points in the finite elements.
![Improved Calculation Performance by Optimized Consideration of Nodal Degrees of Freedom in RFEM](/en/webimage/015531/2983511/Berechnungsperformance_EN_(1).png?mw=512&hash=ea9bf0ab53a4fb0da5c4ed81d32d53360ab2820c)
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" .
