Dishon, M., G.H. Weiss, and D.A. Yphantis, 1966: Numerical solutions of the Lamm equation. II. Equilibrium sedimentation. Biopolymers, 4, no. 4, 457-468, doi:10.1002/bip.1966.360040407.

The Lamm equation has been solved numerically for conditions corresponding to equilibrium runs for a nonlinear concentration dependence of the form s/s0 = (1 + kc)-1. It is shown that the approach to equilibrium is very close to being exponential (in time) as in the case k = 0. We also compare results for the nonlinear case given above with results obtained for linear c-dependence of the form s/s0 = 1 - kc. For relatively high speeds the time required to attain equilibrium may be greatly underestimated by use of the latter approximation. Finally, we present analytic approximations for the concentration distribution at equilibrium and as a function of time.
