3D Capacitor - Electrode Deflection

Hi everyone, we are trying to simulate a 3D capacitor and study the effect of voltages on the deflection.

One electrode is made of aluminium and is ground, the other electrode is made of silicon and has 10V applied to it along with 1 Pa Pressure.

The dielectric medium is Air (Have disabled it in my model)..

I have to simulate and measure the deflection varying the Voltage and pressure.

I am new to COMSOL and i have built both the electrodes...

My questions are

1) How do i place the dielectric (between the two electrodes or covering the whole model) - Since its Air, do i really need a Dielectric
2)How do measure the deflection due to both the Voltage and Pressure applied

Can someone help me please or stleast give some ideas?

Thanks in advance

Regards
Sanjay

I used some of the examples and built this model, however i am still having problems...
The deflection of the electrode is not affected by the Voltage applied but otherwise it seems fine..

Can someone please look into it?

Thanks in advance
