 June 3, 2002, 12:12 DPM Reversed Flow #1 Hendawi Guest   Posts: n/a Hi every one, I'm modeling a water jet heat&momentum transfert PM. In first step, I'm tying to model the continous phase (like what's done in tutorial 14: Modeling Evaporating Liquid Spray). I take a cubic volume; as BC: 1-a velocity inlet face for gas velocity 2-a pressure-outlet face for atmospheric pressure (the opposite face) 3- the 4 remaining faces (lateral faces) are set as outflow. In this first step of modeling the gasous phase, the model is converged but always with the message " reversed flow in 601 faces on pressure-outlet ". If you have any idea to solve this problem, please tell me. Thank you in advance.
