Building a mesh having in a thin gap in between two beams

I am using the piezoelectric devices interface (pzd). Some layers are linear elastic and other - piezoelectric. The surrounding block is air and I defined it with the electrical material model. I want to employ the electrostatic attraction across the thin gap between the two beams. Therefor I need an electrical material to perform force calculation and apply this force as boundary load on the cross section of the gap.
At the moment I am stuck on building the mesh, because the gap in the middle is interrupting the symmetry (at least I suppose this is the difficult point here). I tried to build a mesh on some surfaces and then make a Swept, but I had little success.
What is a good strategy to build a little bit more complicated mesh like this here?
Thanks!

Hi
your model is perhaps easier in 2D, in any case you need the ALE to cope for the deformed air mesh, I would suggest that you cut your air volume with a line in the middle of the gap and have really several >>3 mesh elements per side in this gap region.
You might need the re-meshing option on too

Good luck
