First Steps with RFEM
Description
In this video, the truss is automatically created using the model generator.
A variety of tools help you to create models or parts of structural systems. In addition to copy and extrude functions, RFEM provides special dialog boxes for generating member and surface models.

In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member end releases. In addition to the nonlinearities ‘Fixed if’ and ‘Partial activity’, you can also select ‘Diagram’. If you select the ‘Diagram’ option, you have to specify the according settings for the activity of the member end release. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the release.

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).
- I would like to calculate and design "temporary structures." What do I need for this?
- Which programs can I use to calculate and design power plants?
- 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?
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- Does a user-defined layer composition in RF-LAMINATE need to be shared separately with other users along with the RFEM model file or is this information stored directly in the RFEM file?
- I have modeled two nodes on a surface in RFEM. The results do not show the displacement at these two nodes. How can I obtain it?
- Which add-on modules and programs do I need for laminate and sandwich structures as well as cross-laminated timber (CLT)?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
