Lee Guest Posts: n/a	When I run a roundpipe model(which is a semi-circe,at one end of the pipe the bounday type is inlet,the other end is outlet,and there is a symmetry boundary),I set the outlet boundary as the prescribed flow split(fs=1),but the information file always shows one warning message: * WARNING #001 * FLUID INFLOW DETECTED AT SOME OUTFLOW BOUNDARIES WHERE MASS FLUXES ARE FORCED TO ZERO. IF THIS CONDITION PERSISTS, YOUR RESULTS MIGHT BE WRONG THE OUTFLOW BOUNDARY MIGHT NOT BE WELL SPECIFIED OR THE GRID MIGHT BE TOO COARSE NEAR THE OUTFLOW BOUNDARY but I think I the meshs created are enough fine,so what is the reason to cause this warning message? Thank you very much for your help! Best Regards, Lee
