Hello,

I am trying to simulate an aeroacoustic flow through an organ pipe. this is a 3d case. I have the mesh and its meshed with SnappyHexMesh functionality.i did check mesh and it shows OK. I am trying to validate it with experimental data. In my experimental data i have initial inlet blow pressure at 2 mbar. i tried to set up this case first with p as totalPressure at 2mbar + airpressure and U as pressureInletVelocity . but i got foam fatal error. i checked up youtube for a simulation and applied similar boundary condition. i simply gave a case with Initial fixedvalue velocity and zeroGradient Pressure. Still im getting similar error. I'm confused how to set up the BCs. If any one could help me it would be great.
