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

You can make a table of natural frequency as function of the temperature parameter, and then create a Table Graph. See the graph in the attached file.
