 Below you will find the fortran code I have used in this study (Study 2). The fortran code uses Successive Over Relaxation (SOR) method which is most probably the simplest and most easy to code numerical method. In this code in order to find a solution for a Reynolds number, a previously obtained smaller Reynolds number solution is used as an initial condition to start the iteration process. The relaxation parameters I have used at different Reynolds numbers are tabulated in this Table. At every 50000 iterations, the solution is written to a data file and also the residuals (error parameters) defined in the manuscript are written to an other data file in order to have an idea about the convergence level of the solution.

 The first Fortran code uses Successive Over Relaxation (SOR) method. The second order accuracy code solve the Navier-Stokes (NS) equations. The fourth order accuracy code solve the Fourth Order Navier-Stokes (FONS) equations introduced by Erturk & Gokcol [International Journal for Numerical Methods in Fluids, (2006), 50, pp 421-436]. Visit Study 3 for details on FONS equations.

 Flows inside closed geometries have always been the focus of attention of Computational Fluid Dynamics (CFD) studies. The "lid driven triangular cavity flow" is one of these flow problems and in the literature it is possible to find several computational and analytical studies on this flow problem.
