This paper describes the application of a new and unconventional numerical method for computational modeling of fluidic micro-handling processes. The key requirement for modeling such processes is the ability to simulate flows with large number of complex shaped moving objects. Conventional body-conformal computational fluid dynamic (CFD) methods are not well suited for simulating such flows and here we have employed a new Cartesian Grid Method (CGM) which has the unique ability of simulating these complex flow on stationary Cartesian grids. The method has been used to simulate a generic fluidic assembly process and is shown to predict some interesting features of this process.
