Hello fellow Foamers,

I'm working to verify interFoam for later two phase work with a classic Poisseuile flow test case. I've followed the suggestions on other posts to use pressureInletVelocity as the inlet boundary condition. Since the only results I've gotten show a uniform zero velocity field I suspect my B.C.'s are still not correct. Please see the contents of my boundary files and my control file below. Any suggestions sill be greatly appreciated.

Best Regards,

Stephen
