Friends, when I use fluent to calculate ventilation and heat dissipation in equipment rooms, the flow field results always show numerical anomalies near the outlet. When the speed at the inlet is only 4.5m/s, the speed near the pressure outlet reaches 30m/s. However, other areas of the flow field do not have this problem. I use structural grids, and the quality of the grids is also reasonable. What is the reason for this phenomenon and how to correct it
