Guidelines of Creating Krylov-subspace Macromodels for Lateral Viscous Damping Effects

Yen P-C, Yang Y-J, National Taiwan University, TW

It is well known that modeling 3-D lateral viscous damping effects requires considerable computational resources. Therefore, earlier works on lateral viscous damping were based on the 1-D analytical Stokes and Couette flow solutions [1,2]. Recently, [...]

Proper Orthogonal Modes for Macromodel Generation for Complex MEMS Devices

Lin W.Z., Lee K.H., Lim S.P., Institute of High Performance Computing, SG

In this paper, a novel method for macromodel generation for the dynamic analysis of structurally complex MEMS devices is developed by making use of proper orthogonal decomposition (POD) and classical component mode synthesis (CMS). The [...]

Computation Speedup of Macromodels for Dynamic Simulation of Microsystem

Lin W.Z., Lee K.H., Lim S.P., Institute of High Performance Computing, SG

A doubly clamped microbeam actuated by electrostatic force with squeezed gas film damping is a well-known micro device for many researchers to demonstrate how reduced-order dynamic macromodels are an effective way to faithfully capture the [...]

Scalable Macromodels for Microelectromechanical Systems

Srinivasan V., Jog A., Fair R.B., Duke University, US

A fully automatic macromodeling methodology to generate scalable reduced-order models for microelectromechanical systems is presented in this paper. Krylov subspace methods are used to generate reduced-order models from detailed higher-order models of the device under [...]

Reduced-Order Models of Stress-Stiffened MEMS Structures

Varghese M., Rabinovich V.L., Senturia S.D., Massachusetts Institute of Technology, US

We present a process for generating reduced-order models for stress-stiffened MEMS structures. The models are created using the established CHURN process, which uses non-linear, analytic, energy functions to describe the state of each conservative quasi-static [...]
