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".
Extended Display of Strains in RFEM
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.

How can I permanently save the parameters in the "Units and Decimal Places" dialog box?
- I have deactivated objects by load case. Why are they still considered in the calculation in the corresponding load case?
- Can I export a response spectrum from RFEM 6 and use it in RFEM 5, for example?

- I would like to enter a large spring constant. Is it possible?
- How can I update the graphics driver, and where do I find the current driver versions?
- How can I display the internal forces of a coupling member or rigid member?
- I have activated values on surfaces in grid points, but only get the extreme values displayed. How can I display all values in all grid points as desired?
- How do I get the current authorization file for RFEM 5, RSTAB 8 and other stand-alone programs?
