1. A microelectromechanical device modeling system comprising: a two-dimensional mask database configured to store a first model and a second model, the first model comprising a first region model of a first region of a microelectromechanical device and the second model comprising a second region model of a second region of the microelectromechanical device, the first model and the second model modeling separate structures of the microelectromechanical device; and a processor configured to derive a MEMS model from the first model and the second model.
