Hello, I have tried adding tiny x velocity with e-5 to e-4, I have seen the velocity and continuity residuals now, I have no idea why the last part has a weird display, during the simulation it sometimes appear and go back to a normal line, so I,m not sure if it's a bug for display or something actually went wrong. The contour plot for temperature i got is still the same as before, the centre part  remains 15.
