Usiur,

First: CAESAR II is not the software to look for possible causes of flow induced vibration. BOS Fluids from Paulin Research Group can be the software for you. CAESAR II can be used for your assistance to minimize the problem in the following way:

1) Go for field readings and observe the shape of vibration in your sysyem. By shape of vibration I mean the portions of your system which are vibrating the most i.e. where the peak to peak displacement/ velocity recordings are high. Now go through the modal analysis report of CAESAR II and observe which mode shape best simulates the actual reading at site.Restructure the supporting arrangement and may be support types also to eleminate those modes shape(s).

This can be the only way to get help from CAESAR II to solve this problem.
