Micro-electro-mechanical systems involve complex functions governed by diverse transient physical and electrical processes for each of their many components. This is an example of a coupled-domain simulation, i.e., the simultaneous simulation of different functional units of the device. In coupled-domain problems, such as ow-structure, structure-electric or a combination of both, there are signicant disparities in temporal and spatial scales. This, in turn, implies that multiple grids and heterogeneous time-stepping algorithms may be needed for discretization, leading to very complicated and consequently computationally prohibitive simulation algorithms.
