It is known that the solutions of the 2D Navier-Stokes equations, in bounded domains, are determined by a finite discrete set of nodal values. That is if the large time behavior of the solutions to the Navier-Stokes equations is known on an appropriate finite discrete set, then the large time behavior of the solution itself is totally determined. Here, an upper-bound is rigorously established for the number of nodes needed to determine the solutions of the Navier-Stokes equations in two dimensions with periodic boundary conditions. © 1992.
