Temperatures not converging

Velocities and pressure results of my Python code for SIMPLER algorithm for laminar flow through a 3-D duct are converging and giving correct values. The temperature results from energy equation solution are not converging and not giving correct values. Constant wall temperature boundary condition. Any tips, please.

Maybe there is a bug in your code. Or perhaps there is an elephant.
Either, you describe what your code does in pseudo-code or just dump it here and pray that someone reads it. SIMPLEX is a method to solve the continuity & momentum equation, it says almost nothing about how you solve the coupled system of equations involving the energy equation. |

Thank you for your reply and concern shown.
I uploaded a pdf-file showing the pressure and u-velocity grids. I will be thankful if you can answer my question. With warm regardss, Dharma Rao Vedula |

All you did was draw a grid which isn't even a grid. It's a line with dots and bars on it and no indication of whether you are doing FD, FEM, or FVM. The reason your temperature cannot converge is because you have no code!
