Hi,
I have a question regarding simulating temperature coefficient of frequency in COMSOL. I want to draw the curve of TCF for Lithium Niobate, so I defined temperature as a parameter and consider the effect of temperature in elasticity matrix ( I wrote elasticity module in terms of temperature). After that I perform the Eigen-frequency simulations to find the desired mode shape and observe the variations of frequency for each temperature. I wrote the frequency for each temperature one by one and then draw it in Matlab. However, I think this method is a quite bit time-consuming. Does anybody know a way to plot TCF curve directly in COMSOL, like other plots? or at least export the data of variations of frequencies to Matlab ?
Thanks in advance for your help
Thanks for your answer. I saw some tutorial about drawing stress and strain versus the force, but I do not know how I can I define my parameter here. My study here is eigen-frequency study and I want to see the frequency variation of one specific mode with temperature. Have you done any simulation like that? I would appreciate send them to my email if you have any.

Yes. Thank you very much.
Here is my file. In this file, I did parametric sweep for a n-type silicon. I want to plot the variation of resonance frequency in width-extensional mode (happens at 54.6 MHz here) with temperature in Comsol.
