You just need to define a component of volumes that represent the air.  You
select those volumes and then use the CM command to define a component.

Subject: [mems-talk] ANSYS ESSOLV modelling ?


Hi fellas,

Is there anyone, who had run already a coupled field " Electro-Structural "
analysis using ESSOLV macro under Ansys ?
My model is a basic MEMS swith, that needs to be solved in 3D.

I am familiar with the FEM modelling (meshing, loading, boundaries, etc). I have
created the Structural and the Electrostatic physics files, and I'm stack with
the air gap issue and how to declare the volume component for morph region for
example, etc

Please advise,

Souheil,

Many thanks
