I have noticeably long calculation times in RFEM 6 (Add-On Stahlanschlüsse / Steel Joints) and request assistance.
Problem:
Hi Mzabi2025,
Thank you for your message!
To analyze the problem more precisely, the model file would be very helpful:
Click on File → Save As and choose the following settings to reduce the file size:
Then upload the file here (e.g., *.rf6, *.rs9) – this way the community can also contribute to the solution.
Don’t want to share the file publicly? No problem – send it to me via direct message: click on my profile picture or my username → Message.
Best regards

Hey, I know the problem very well and unfortunately fear that it generally takes a long time to load when using the addon, but I have also heard that Dlubal's development team is already working on optimizing it.
Recently, I solved it by first creating the connections in the main model, then in the 2-window view, copying the connection including the connected bars from the main model into a new file in the second window using ctrl+c → ctrl+v.
In the second model, I then give the “supported” bar end a fixed support and switch off the self-weight.
Then I shorten all the “long” bars at the connection so that only the last 1m of the bar remains.
Now I read off the maximum internal forces (initially the enveloping ones) from the main model for each bar at 1m intervals and apply these as nodal loads at the end of the respective 1m bars in the connection model. Of course, you have to spend some time thinking here to make sure you are on the safe side, or possibly read off more than just the max value of the envelope and create a few nodal loads. (For buckling, for example, small compressive forces can sometimes be more critical than high tensile forces, etc.)
Even though it takes a bit more effort at first, the savings in calculation time are so great that it is almost always worth it!
