Dear all,

Coul d anyone please tell me how to model thermoelastic damping in mems resonator using anisotropic material. In this paper "Thermoelastic Damping in a MEMS Resonator", the author just use solid model: isotropic. But when I change to anisotropic, the simulation get error.

Thanks advance!

Hi, I think you forgot to enter some material properties, like: coefficient of thermal expansion, thermal conductivity and heat capacity at constant pressure....

I have no problems with my anisotropic TED simulation....
