FSI Modal plate with fluid

Jorge22 · August 9, 2016, 15:39

I want to solve the following problem: A plate has a body of inviscid water on top of it, with a free surface. It is required to obtain the frequencies of vibration of the plate considering the water interaction.

I have been looking for examples in ANSYS. The module Transient Structural is used, but not Modal. I have tried to do it myself but haven't succeeded.

Any suggestions?

CFX does not support modal analysis. You are going to have to run this as a transient FSI simulation and sweep a range of excitation frequencies.
