TED in MEMS resonator

Hi

I am new to COMSOL. I was trying the Thermoelastic damping in MEMS resonator model [it was done on 3.5 but my version is 4.2a] provided by the comsol. Although I get the similar eigenfrequencies but not getting any Q-factor [shows error] value nor the temperature distribution correctly. How to evaluate the Q factor for TED in COMSOL? Also can some please explain the TED modelling in comsol?

Any help on TED would be appreciated. Thanks
