How to avoid reversed flow in ** faces on pressure outlet ***??
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.
Please, give me any suggestion to avid back flow, I stuck in this situation.
