I've run a frequency analysis for the real model and for the simplified one (both have the same mass, location of gravity centre, material,fixtures, properties of study..) and i obtained the list of resonant frequencies for the 30 first mode shape;both have similar and acceptable results.

the problem is that for the simple model I've obtained the results for the 30 frequencies but for the real model only the 10 first ones.

I need to write a report comparing both results and resonant frequencies lists, but i need the rest of results for the real model to do it.

how can I solve this?

is it possible that the software struggles showing the rest of results due the complexity of the model?

Thanks a lot in advance.
