Multipole BEM for the evaluation of damping forces on MEMS

摘要

A procedure for the analysis of 3D Stokes flow around complex micro structures (MEMS) is developed with the aim of evaluating damping forces. First kind integral equations employing single layer potentials are utilized and the linear system stemming from their discretization is solved by a GMRES iterative procedure with multipole accelerators. Issues pertaining to the conditioning of the linear system are discussed with reference to the examples presented.
