I am trying to study the vibrational eigenfrequency of a silicon nanostructure. I have built the geometry and when I try to define the materials, I used single crystalline Si with anisotropic properties in which I could define the elasticity matrix that I obtained through other calculations. However I noticed that the elasticity matrix doesn't have a check mark in front of it, so this information is not required in this case. I know there must be something that I did wrong, but I am kinda new to COMSOL and any suggestions would be greatly appreciated! Thank you very much!
Best wishes,
Vincent
