While I run "electromechanics" module for a MEMS resonator beam, I select "Prestressed analysis Eigenfrequency". Now my question is whether COMSOL considers the Electrostatic Spring Softening which solving?
Electrostatic Spring Softening is the change in the natural frequency of a MEMS structure due to presence of the Electric field in surrounding the MEMS structure. There is always a reduction in stiffness of the Mems structure which reduces the natural frequency, thus called spring softening.
Is there any option to toggle "Electrostatic Spring Softening" effects so that we can compare the results with and without spring softening?
