1. In a Computer Aided Design (CAD) Environment, a method for automatic mesh generation comprising the steps of: composing a schematic MEMS(Micro Electro-Mechanical Systems) design suitable for system-level simulations, said MEMS design including a plurality of components, each said component of said plurality of components being associated with a mesh generator, each said mesh generator being computer instructions describing how to create a mesh for the associated component; providing a mesh generation tool, said mesh generation tool using said plurality of mesh generators to generate at least one mesh that represents at least one of a MEMS device that is the subject of said schematic MEMS design and a user-defined sub-assembly; and using said mesh automatically generated from said schematic MEMS design as input for a numerical PDE (Partial Differential Equation) solver in a simulation environment, said PDE solver verifying approximations made in said system-level simulations of said MEMS design.
