How to use deformed mesh ?

Hi,

I want to simulate two physics sequentially: the first one is solid mechanics and the second one is electrostatic. My geometry is simply two parallel plates and want to sweep of the force and get the capacitance reading.

I add the deformed geometry(dg) physics and included in "step 1: stationary" along with solid mechanics. I include the "prescribed deformation 1" in deformed geometry(dg) physics and set the prescribed mesh displacement as u, v, w. It also says it overrides "the fixed mesh 1".

Then in "step 2: stationary", I include "electrostatic", but in the mesh selection, I can only select "Mesh 1" witch is the original mesh.

Is it alright that I use (dg) instead of (ale).

Could you tell me how to setup the (dg)/(ale) itself and how to include them in the study step and include the deformed mesh?

I am using version 4.2 btw.

Thanks.

Best,
Stacey
