Hello friends, I am new to CFD, and I am trying to solve the De Vahl Davis paper on natural convection of air in a square cavity, a benchmark numerical solution. I am solving this using numerical methods by solving u,v momentum equations, then solving the energy balance equation using the SIMPLE algorithm on Fortran. I got the solutions for every value of Ra, Pr for u, v, and T. Now the problem I am facing is finding the stream function and vorticity using the solutions I got. I tried discretizing the given stream function vorticity equation, but I am not getting the desired results.
What I get is a combination of graphs of u and v. I will be grateful if anyone can help me. |

In order to get the stream function field, solve the Poisson equation with homogeneous BCs. |
