Exitation frequancy Vs range of frequancies in parametric solver

Please login with a confirmed email address before reporting spam

Hello;
I have 1 geometry with 2 physics (piezo plane stress and acoustic pressure). In scalar variable from physics tab I enter excitation frequency for one physics and synchronize it for the same physics to 200000 Hz.
In solver parametric when I chose analysis type frequency response and for solver I use parametric, I should enter a range of frequencies also and by running Comsol it runs for the range of frequencies that has been defined in solver not excitation frequency.!!
Which frequency would be really my excitation frequency? As I should define maximum element size base on excitation frequency.

Could you please someone tell me what is the difference of excitation frequency in scalar variable and range of frequencies in parametric solver? Does Comsol automatically when solve parametric solver consider the range of frequencies as excitation frequency?

Thanks
I also attached my model.

Set the excitation frequency to an arbitrary variable (ex. "freq"). Then in the parametric sweep, define that variable over the range you want.
