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).
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How can I perform the stability analysis in RF‑/STEEL EC3 for a flat bar supported on edges, such as 100/5? Although the cross-section is rotated by 90° in RFEM/RSTAB, it is displayed as lying flat in RF‑/STEEL EC3.
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- Why are my imperfections displayed graphically in different ways and can I adjust the display?
- Is it possible to manually specify a longitudinal reinforcement for design in RF‑PUNCH Pro?
- Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
