Ciao!
I have ran a case in HVAC system with multi outlets. I got the warning "reversed flow in *** faces on pressure outlet" in two outlets. the residuals are straight horizontal and the didn't fall below 1e-1. So the results are not converged. How can I fix the problem to got a converge solution? I am wonder if this back flow is one of the reason that I cannot got converge or not? How can I avoid Back-flow? I refine the mesh, but still the same problem. Ps: inlet set as mass flow inlet, outlets are set as outlet-vent or pressure outlet. Thanks. Last edited by Tarantino; March 22, 2013 at 21:59. |
