Abstract

Trajectories of superparamagnetic sub-micronic particles submitted to a multi-force field are modeled numerically by a Finite Element Method. The first step is the computation of the magnetic forces and the carrier fluid velocity field, the second step is the computation of the trajectories using a Finite Difference Method with a predictor-corrector scheme.
