Dear all,

I am working on a modal analysis of a model airplane with an attached air data boom (adb). I have already run many simulations that worked out fine but recently SW started to crash, whenever I changed something on this particular file. 

What I need are the modes 7-12 of the frequency analysis which shall show interferences between the wings an the adb which are connected through a system of poles and strings. 

I have attached a zip file of my assembly and its parts and would be glad if somebody could help me out on this.

Thanks a lot,
mathias
