Convergence in the L2 and L∞ norms of the Lagrangian displacement, velocity, pressure, and wall shear stress (WSS) for the two- and three-dimensional circulat Couette flows. The Lagrangian pressure and wall shear stress are computed from the side between the two cylinders. Simulation parameters include Re = 100, Δt = 0.05hfinest, and Mfac = 2.
