Reply To: Probem with modal Analysis

Hi

Yes, wet modes are the important ones in the end of the day, and you can not do that (vibroacoustics is not an option) -

the paper I sent if you looked is not from us, but it is to show how you calculate (and what tools you use) wet modes using Nastran that has a speical method to do that and is the common tool for doing this calculation. So if you have that tool it is very easy to do, see the paper where they actually explain the theory and the commands to be used in detail.

We said that there used to be a Guyan reduction in Ansys APDL, but it is not available anymore.

Thank you

Erik
