Direct simulation of the motion of a settling ellipsoid in Newtonian fluid

In this paper, we discuss the generalization of a Lagrange multiplier-based fictitious domain method to the simulation of the motion of general shape particles in Newtonian fluid. Preliminary numerical results of a settling ellipsoid in a narrow channel filled with a Newtonian fluid are presented. As expected, the ellipsoid turns its broadside to the stream in the simulations.
