The physical simulation of articulated rigid bodies is of great importance for feature film production. For complex articulated system, this process requires computationally efficient methods for solving large and sparse systems of equations. We present a discussion of different iterative solvers for such type of linear systems. We considered several different preconditioners for each iterative method and discuss their efficiency. Physical simulations make use of Stanford's physics simulation software PhysBAM.
