SubscriberI'm running a modal analysis of a cylindrical shell to obtain its natural frequencies for different modes. To start with, I'm trying to run a simulation for verifictaion with existing results in papers. I've selected to following results. (source- Vibrations of Cylindrical Shells)
While I know the meaning of the terms m and n, I can't get around as to how do I input these when running the modal analysis.
When I run the simulations myself for these dimensions and material properties, I'm getting the following results.
To replicate the clamped-clamped boundary condition, I've added fixed support in both the end faces.
I'm unable to get similar results to verify my working.Â
What am I doing wrong, and how to procced.
Thanks in advance for help -

SubscriberI got it. I was interpretating the results wrong. m and n values are not something you input, but check for from different modes.

Ansys EmployeeHi
That is good - yes m,n often refer to the eigenvalue/vector corresponding to a specific mode.
