The problem is two-dimensional square cavity flow incompressible viscous flow in a typical flow. Although it is still analytic solution can not be obtained, but it is often used as a test of various numerical algorithm to calculate the accuracy and reliability of the numerical examples. Most algorithms are almost the literature it been calculated. Third-order upwind finite volume method using Discrete format in this example it solved numerically.
