Hi everyone,

I am trying to use multiphaseEulerFoam in a cylindrical geometry with cylindrical walls as the inlet. In my case, the inlet is coming from all around the curved cylinder walls (the red face in the attached figure).

I am looking for a boundary condition that applies the inlet velocity according to each cell's normal vector, so that the gas would flow from the walls to the center (the green face is the outlet in my geometry).

I've tried pressureInletVelocity, as it was suggested in another forum, but that didn't work.

I would appreciate it if you have any suggestions or if you have experience with a similar case, share your thoughts on this with me.

Dear troy,
Yes, Thank you that's something I was looking for.
