Hi friends,
I'm using driven modal soultion & Eigenmode solution for a very simple cavity resonator.
Structure: A cubic air filled cavity
Driven modal: I'm using a coax as an excitation
Eigenmode: Keep the whole structure in the driven modal
Results: For these two types of solution, i have different resonant frequency, they didn't match each other. But i thought it should give the same resonant frequency for both.
Can anybody help me on this? Really appreciate!!
