I'm running a simulation with a cylinder domain where the curved wall acts as inlet-outlet depending on the direction of the flow. I'm using simplefoam with atmBoundaryInletVelocity in the inlet-outlet U to simulate an ABL.

I have a problem when defining the pressure boundary condition for the inlet-outlet as a freestreampressure boundary.

When i use this boundary condition simplefoam exits returning a non-zero exit code.
i tried setting the boundary of inlet-outlet to fixedValue and it works fine with that, but I believe this boundary is incorrect.
