First Steps with RFEM
Question
I have the SHAPE‑THIN 9 license, but I cannot transfer the created cross-section into the RFEM program. What is the problem?Answer
The problem is in the RFEM version. SHAPE-THIN 9.01 was released together with the RFEM version 5.22.01. The files created in SHAPE‑THIN 9 have the format *.du9. The RFEM versions older than 5.22.01 do not recognize this extension, and thus the cross-sections created in a newer version cannot be loaded.Keywords

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 cannot manage to correctly import the cross-section from a dxf file into the SHAPE‑THIN program, the imported cross-section is in a wrong plane. What can I do?
- The installation of a Dlubal Software program is not possible due to the following message: "Program unsafe, protection by Microsoft Defender SmartScreen." How can I install the program?
- I get the following message when starting all installed Dlubal programs (also when running as administrator): "The application was unable to start correctly (0xc0150002)." What can I do?
- In SHAPE‑THIN, I get the error message saying that the material library cannot be opened. I have reinstalled the program and integrated the material library of another computer, but without any success. What should I do?
- The calculation of a file runs smoothly for my colleagues, but I get the message "Calculation stopped" for the same file. What should I do?
- When starting the Dlubal Software programs, the error message "Server is busy" appears. My colleagues do not experience this problem. I have already tried to reinstall. What should I do?
