Downloads : Numerical Solutions & Codes   Many researchers have contacted me and requested the Fortran codes I have used in my researches. Click on the link below to goto download page for the Fortran codes that I wrote. Those Fortran codes solve the 2-D steady incompressible driven cavity flow problem using different numerical approaches. I have added many comments into the codes for easy understanding.

FORTRAN CODES FOR DRIVEN CAVITY FLOW

 Below you will find the fortran code I have used this study (Study 4) for the triangular driven cavity flow that uses Successive Over Relaxation (SOR) method which is most probably the simplest and most easy to code numerical method. In this code at every 25000 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.

FORTRAN CODE FOR TRIANGULAR CAVITY FLOW

Below you will find my numerical solution datas for 2-D steady incompressible triangular cavity flow at various Reynolds numbers with various triangle geometries, obtained by solving the 2-D steady Navier-Stokes equations in streamfunction and vorticity formulation using Successive Over Relaxation (SOR) numerical method. In these solutions, the number of grids used is 513´513. The data files are binary. Use the fortran code at the bottom to read the binary files and also to check the accuracy of the solution. These numerical solutions satisfy the steady incompressible streamfunction and vorticity equations with very very low residuals.

Email me if you need any help with these fortran codes or data files or if you have any comments or suggestions. Please acknowledge this web site if you use these files in your studies.
