I am seeking to set a constraint that makes the resonance frequency of the 2nd mode to be six times the amount of the 1st mode while retaining the modal stiffness to be in a certain ratio that I can freely manipulate.
I am hoping to use ANSYS to do a topology optimization to provide me with different shapes of an object that could possibly fit my criteria, does ANSYS have this capability?
My current progress so far is that I am able to extract the modal stiffness data from ANSYS utilising kinetic energy and the natural frequencies given. I been looking into APDL commands with no luck so far on finding a solution on how to execute this topology optimisation.
Thank you for your time for reading this post, have a great day.
