    Hello everyone!

    I am designing a pontoon with a set of mooring cables in order to carry out a fatigue analysis of this. To do it, I think that is necessary to find the natural model of the system in order to obtain the biggest displacements of the structure and hence, the biggest tensions in the mooring cables.

    I have obtained the fundamental frequency of the pontoon without taking into account the set of mooring cables through ANSYS AQWA, however I don't know if it is possible to obtain the natural mode frequencies of the system. Does anyone have experience in this?

    Thanks in advance.
