Using 3T3 cells as a model system, the motion of each individual cell was calculated using a one-way coupled Lagrangian method. The cell was assumed to be a solid sphere, and interactions with other cells were only considered when a cell sedimented in the trap. The ordinary differential equations were solved along the cell trajectory for the three components of the velocity and location vector by using the Rosenbrock method based on an adaptive time-stepping technique.

The “flat-type sieve” consists of an array of nine sieves arranged in a symmetric diamond-shaped pattern. Under simulated conditions, sieves closer to the chamber entrances captured cells well for both geometries, while the downstream sieves remained empty.
