Computer-aided analytical tools generate methods for designing MEMS eliminating some expensive and cumbersome building and testing. We need accurate simulations: accurate both in representing a structure's geometry and its underlying constitutive properties. We also require behavioral models for the device as well as its electronics. Most devices are transducers. Transducers operate in multiple energy domains and strongly couple among these domains (e.g., coupled electro-mechanical and fluid-structure interaction). Transducer-like devices require specialized analysis together with accurate 3-D simulation. Again, designers of these things have diverse backgrounds, and the field is multi-disciplinary. Because not everyone is conversant with everyone else's tools and procedures, we need to develop more user-friendly analytical tools. For instance, should electrical engineers need to perform finite element analysis of a mechanical structure or should mechanical engineers need to simulate an electronic circuit, they should have suitable interfacing tools.
