We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I have followed your steps (including patching), and got the following results. I also set the gauge pressure at both pressure outlets to 0 Pa as per point 3 - /courses/wp-content/uploads/sites/2/2024/01/2041750.pdf. Mass flow rate exiting the chimney seems to have converged within around 5%, and the values are realistic. Contours and vector plots are much better and closer to expectation. However, residuals remain high. There is some reverse flow as pictured, could this potentially be causing convergence issues?
