Hi all I have a problem with eigenfrequency and frequency domain, I hope someone can help me to clear I using PDE Coefficient form, and solve my problem in 2D, with independent variable (u) = scalar. With eigenfrequency, I found 1st mode = 382 (Hz), and 2nd mode ( 609Hz), 3rd mode = 817 (Hz) But problem is that when I use Frequency domain with f= 609(Hz) or 817(Hz), the result alway similar to 1st mode frequency Please see my attatched file
