Hi, i want to simulate the thermal stress effect (e.g. temperature and heat flux) on prestressed eigen frequency analysis of a MEMS model which has built in "Electromechanics" and has input voltage, but i haven't seen any changes in results in natural frequencies, like COMSOL ignoring the thermal stress physics for eigen frequency analysis. can anyone help?
Thanks in advance
Hello Mahdi,
What you need to do is to add two study steps, "Stationary" and "Eigenfrequency". "Stationary" study should perform the stress analysis. Results from this study need to be passed to "Eigenfrequency" study for successful implementation.
This can be done automatically by selecting "Prestressed Analysis, Eigenfrequency" study. A few such examples with this study type are also present in COMSOL Model Library.
