Electric field not adjusting with moving mesh

Hi,

I have created a model which is effectively a capacitor with a moving plate. I have ground electrodes on the fixed top plate and +/-100V electrodes on the bottom moving plate. I am using ALE with an oscillating displacement to move the plate.

For stationary analysis when the electrodes are overlapping I can see a very strong electric field and when they are totally not overlapping, the E field is quite a bit weaker. This should all be accurate but when I do a time dependent analysis to move the bottom plate, the electric fields are not changing whether the electrodes are overlapping or not.

Please see the attached images. "0 off" is when there is total overlap, "15 off" is when there is no overlap, and "moving 15 off" is when the bottom plate starts off with no overlap and oscillates back and forth.

What am I missing in my model in order for the electric field to continually adapt to the top plate?

Thanks,
Jeff
