Simulation of micro pumps is complicated by the interaction of various physical domains. The fluid structure interaction (FSI) essentially determines the dynamics of micro pumps and therefore has to be taken into account. Mesh based approaches are in this context very time consuming, though very accurate. However to perform parameter variations and optimizations usually simplified analytical and numerical models have to be set up. In this paper we present a modular approach where FSI has been taken into account within a system simulation based on lumped models using the multiphysics simulator SABER. For the first time we report on a simulation toolkit used for simulation of two different micro pump layouts, well known from literature.
