Hi guys,

Im working on simulation of telescopic boom. I make buckling analyses of pair of sections and adding stiffeners to have higher BLF. Problem is that if I set simulation to find 49 modes all of them are negative. When I set 50 modes, simulation finishes with fatal error that, Im looking for too many modes. Any idea how to solve that? Never had this problem.

Thanks,

Mike
