Convergence on CFD

      Hi everyone, I am working on simulating heat ventilation within an enclosure. To achieve convergence in the model, I had to reduce the time scale factor multiple times. Once I reduced it to 0.0002 seconds, the model converged within a few iterations. Is this acceptable? TIA!

      Hello,

      You cannot judge the convergence only based on scaled residuals. Please check for the report definitions and net mass flow and net heat flow rates.

      No. Run more iterations to ensure it's actually converged and you've not just confused the residual equation maths. How do the fluxes and monitors look?
