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).
- How can I create a curved or curved section?
- Does the load generation also work for curved members?
- I would like to calculate and design "temporary structures." What do I need for this?
- How is an inflatable object simulated in RFEM?
- 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?
- I often edit the reinforcement provided by the program. Adjusting the reinforcement by using coordinates takes much effort and time if having several beams in the model. Is there any way to speed up the reinforcement editing?
- Which programs can I use to calculate and design power plants?
- Which filter settings should be selected in the material library for concrete in order to perform design in RF‑CONCRETE according to the Swedish National Annex? In RFEM, there is no Swedish standard group available for the selection.
- I have analyzed two models of an inclined bored pile as a support with defined spring stiffness. A surface that can be moved horizontally (globally) is used for the force transmission. The bored pile in Model A is a support inclined by 15° with a spring stiffness of 2,000 kN/m in the axial direction. The bored pile of Model B is a support with the defined spring stiffnesses, divided into the respective horizontal and vertical components. The value of the spring stiffness is always the same (2,000 kN/m). In my opinion, both models are equivalent. Why are there different results in the deformation anyway?
- In the filter settings for the values on surfaces, you can display a certain range of results and hide the rest. How can I hide a certain range of values and display the rest?
