different results single frequency/sweep in the frequency of the applied...

I'm trying to solve a simple problem in which I compute by Comsol the displacement of the upper boundary of a metal film, when the film is subjected to a mechanical load. The problem is that I obtain...

Hi Lucia, I guess that if you have imposed a sinusoidal load at a fixed frequency (i.e. a load which varies in time) you have performed a time domain simulation. If it is your case, maybe you have to...

Hi Alessandro, thank you for your answer. The problem is that I get the correct (= predicted by theory) answer when I use the sinusoidal load. In my simple case (which is a first approximation of more...

Dear Lucia, I think that the right variables you have to choose in the frequency domain approach are "Disp. amplitude x-dir" and "Disp. amplitude y-dir". When you run a frequency domain analysis,...

Thank you again, Alessandro. You are right, I also got to the same conclusion on my own. The problem is that both the values of "Disp. amplitude x-dir" and "Disp. amplitude y-dir" are not correct. They...
