I am having a problem in setting symmetry and free constraints because that overrides electromechanical interface. And as a result it is showing wrong diaplacement and capacitance change according to the voltage (electrical constraint) not as a change in displacement due to the application of pressure as boundary load which is desired..

In comsol 5, how can I unmark preserve aspect ratio check box so as to see actually what is happening?
