Souheil: 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. Regards.

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 --------------------------------- Yahoo!
