document: An efficient DIPIE algorithm for CAD of electrostatically actuated MEMS devices Pull-in parameters are important properties of electrostatic actuators . Efficient and accurate analysis tools that can capture these parameters for different design geometries , are therefore essential . Current simulation tools approach the pull-in state by iteratively adjusting the voltage applied across the actuator electrodes . The convergence rate of this scheme gradually deteriorates as the pull-in state is approached . Moreover , the convergence is inconsistent and requires many mesh and accuracy refinements to assure reliable predictions . As a result , the design procedure of electrostatically actuated MEMS devices can be time-consuming . In this paper a novel Displacement Iteration Pull-In Extraction -LRB- DIPIE -RRB- scheme is presented . The DIPIE scheme is shown to converge consistently and far more rapidly than the Voltage Iterations -LRB- VI -RRB- scheme -LRB- > 100 times faster ! -RRB- . The DIPIE scheme requires separate mechanical and electrostatic field solvers . Therefore , it can be easily implemented in existing MOEMS CAD packages . Moreover , using the DIPIE scheme , the pull-in parameters extraction can be performed in a fully automated mode , and no user input for search bounds is required
