Hello everyone.
I am trying to solve a eigenfrequency problem with PDE model. The structure in my model is very simple(a square and a circle in it),the material of it is elastic . Of course the Structural Mechanics Module can solve this problem too.But I encounter a problem.The results of PDE and Structural Mechanics Module are different.But when I use them to solve a more simple structure(just a square).The results are same.I don't know why.Can you help me? This problem is very important for me.Thank you very much!
Here is my model in attach files.
