In RF‑/DYNAM Pro, the "From self-weight of structure" option is available in a mass case. Is it always necessary to activate this option in order to consider the dead load of the structure?
After calculation in the RF‑/DYNAM Pro - Equivalent Loads add-on module, the size of my file has increased significantly. The performance has worsened enormously. What could be the reason for this?
I would like to perform seismic design of an irregular structure. Does RFEM automatically carry out the modal analysis (consideration of multiple vibration modes) on the spatial system, or do I have to use special settings for this?
When performing a dynamic calculation, I get the message: "The model has no free mass assigned. Therefore, dynamic calculation is not possible" or "Too many eigenvalues required". How can I calculate mode shapes?
In RF‑/DYNAM Pro, I get error message No. 10040: "It was impossible to calculate all eigenvalues with required accuracy. [...]" How can I fix this error?
The RF‑/DYNAM Pro add-on module has the parameters "Modal mass", "Participation factor", and "Equivalent mass". The manual contains the formulas, but an explanation and hints on how to use them would also be helpful.
