Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
Product Feature
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 (e.g. trusses and membrane structures).

Failing Support Conditions for Contact Surfaces
In order to create a surface model with failing supports close to reality, an option called "Failure if contact perpendicular to surfaces failed" is available in RFEM 5 for contact solids under "Contact Parallel to Surfaces".

Is it possible to change the properties of members or surfaces in the individual construction stages, such as their location?
- I am trying to import a DXF file. The file can be imported into the model, but it does not have the correct scale. Where is the problem?
- Is it possible to apply a factor to the loads of one or more load cases that uniformly increases or decreases all loads in these load cases?
- When exporting to Excel, I get the error message "Microsoft Excel is not installed on this computer" although Excel is installed. Why?
- Is the German National Annex 2021‑07 to Eurocode 8 available in RFEM 5 / RSTAB 8?
-
How can I permanently save the parameters in the "Units and Decimal Places" dialog box?
- Can I export a response spectrum from RFEM 6 and use it in RFEM 5, for example?
- I have deactivated objects by load case. Why are they still considered in the calculation in the corresponding load case?
- What is the maximum number of reinforcement groups that can be created in a design case in RF‑CONCRETE Surfaces?
- I would like to enter a large spring constant. Is it possible?
- I am trying to import a DXF file. The file can be imported into the model, but it does not have the correct scale. Where is the problem?
