(astrophysics, astronomy) A method to develop triaxial equilibrium kinematic models of actual galaxies (without knowledge of the motions of the component elements of the actual galaxies) using a grid and assigning masses and orbits, simulating gravitational evolution with the resulting estimated distributions, to compare with the actual galaxy, until a model results in similarity with the actual galaxy.
