Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
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).
Frequently Asked Questions (FAQ)
- How are the signs to be interpreted for the releases, results of line releases and line hinges?
- How can I create a curved or curved section?
- After the design with RF-/TIMBER Pro, I had a cross-section optimized. Why is the utilization of the optimized cross -section now exceeded?
- Is it possible to design the support pressure or the sleeper pressure in RX-TIMBER?
- Why are the stresses of the 90 ° orientation not displayed in RF-LAMINATE for a layer with the orthotropic direction 90 ° for σb, 90?
- How can I get the member end forces to design the connections?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- How can I run the RX‑TIMBER Frame plugin? I did not find it in the Add-on Modules menu nor in Project Navigator - Data.
- I have a question about the results of the serviceability limit state design: How is the increment of the dead load by the factor 1.8 and the imposed load by 1.48 explained in the result combinations for the SLS design?
- Where can I adjust the effective length lef according to Table 6.1 of Eurocode 5 in the TIMBER Pro add-on module?
