Problem with beam188 Modal Analysis!!!
Problem with beam188 Modal Analysis!!!
(OP)
Hi,
I ran a modal analysis of a I section cantilever beam with beam4, beam8 and beam188 elements. Beam4 and Beam44 produced the same frequencies. But results with Beam188 differ from Beam4 and Beam44 . Can anyone explain the reason for this behavior?
