Hello fluent users
I simulate flow and heat transfer for air stream in a cylinder with heated walls. I try solve the problem and even when my solution seem converged, the outlet massweighted static temperature is not stable as you can see on the diagram below. After 2000 iterrations i use descretization second order upwind for energy as it is recommended by the users manual and i reduce the under-relaxation factor for energy to 0,8. The mass flow report seems satisfying Mass Flow Rate (kg/s) -------------------------------- -------------------- airin 0.0020031099 outlet -0.00200311 ---------------- -------------------- Net -1.2356829e-10 I want your opinion if my simulation is converged. Thanks |
