Hello,

I realized a calculation model under CAESAR II 2019 SP1.
Several static cases and static combinations have been successfully created and executed.
I wish to carry out the analysis of the earthquake of this model by a spectral dynamic calculation.
So I configured dynamic analysis with the load data for my project.

When the modal analysis is executed, it never stops.
Forcing the stop of the modal analysis leads to the generation of the results but the Sturm is not good. The analysis is incomplete.
I have to determine the modal analysis until a frequency of 33hz.
I have set a maximum limit of 1000 modes.

I don't understand where the problem comes from.
We have the same problem on other computers.

Thanks for your help.
I can share the model if necessary.
