Hi,
I'm currenty trying to model the eigenfrequencies of a thin cylinder ansiotropic silicon cylinder as a fucntion of temperature in COMSOL 5.3a.
I have measured data for the material properites of the geometry between 4K-300K which i have loaded into the model and performed a parameter sweep through each of the properties while varying a temperature applied to the body.
Comparing the results of this model to measured data of eigenfrequency vs temperature yeilds very different results than I would expect. I am wondering if this is the best way to go about solving this kind if problem in comsol or if there is something that i am missing
