This paper presents a new and general method to include mechanical finite element models within an electronics simulator. The approach used directly transforms a finite element into an equivalent electrical network. With that, we accomplish integrated simulations of electronics and complicated, irregular mechanical structures which are very typical in microsystem technology. The methodology can be applied to all analog circuit simulators containing capabilities for analog hardware description languages and a procedural language interface.
