Efficient 3-D Numerical Code “FastSlipStokes” for Drag Force Calculation Due to Slip Flow

Ding J., Ye W., Georgia Institute of Technology, US

Drag force calculation due to slip flows is important in predicting the performance of the microstructures with minimum feature size around 1 mm. In this paper, an efficient numerical approach to compute the drag force [...]

Simulation Based Design of O2 MEMS Sensor

Andjelic Z., Krippner P., Vogel A., ABB Corporate Research Center, DE

The paper presents the methodology for the Simulation Based Design (SBD) of MEMS sensors influenced by mechanical and electromagnetic phenomena. The complexity of the problems mostly asks for both the efficient 3D numerical technologies and [...]

Analysis of Realistic Large MEMS Devices

Ljung P., Bächtold M., Spasojevic M., Coyote Systems, Inc., US

A high-speed high-accuracy 3D field solver for the solution of coupled multi-physics encountered in MEMS is presented. The software AutoMEMS enables automatic model generation from layout, automatic meshing, adaptive mesh refinement of large complex geometries [...]

Robust Algorithms for Boundary-Element Integrals on Curved Surfaces

Wang X., Newman J.N., White J.K., Massachusetts Institute of Technology, US

This paper presents a new approach to computing 1/r singularities on curved panels. By using carefully chosen mapping techniques, a curved panel with curved edges is mapped to a at panel with straight edges. Analytical [...]

Creation of 3D Surface Models from 2D Layouts for BEM Anaylysis

Spasojevic M., Ljung P., Bächtold M., Coyote Systems, Inc., US

In this paper we present a new approach to creation of 3D surface models of MEMS devices from 2D layout masks suitable for analysis using the Boundary Element Method (BEM) [1]. The algorithm is implemented [...]
