Hi,

I would like to use a boundary condition at an inlet that allows a pressure-time profile to be specified, which is also non-reflective.

Currently I am using timeVaryingUniformFixedValue to create the pressure-time profile at the inlet, but I think I am getting reflections at the inlet. I have tried timeVaryingUniformInletOutlet which doesn't seem to help.

Can anyone advise if a boundary condition exists which does this?

thanks
