Nastran Normal Modes Analysis - getting the same modes?
Nastran Normal Modes Analysis - getting the same modes?
(OP)
I am doing a simple normal modes analysis on a high AR wing which has been meshed and verified. All I want to do is compared the normal modes of the clean wing to a wing with added point masses (added through CONM2 elements).
For some inexplicable reason I am getting exactly the sames modes for the wing with point masses as the one without point masses?
I must have missed something utterly basic, does anyone know what it could be?
