That's pretty much what you should do: leave the wall extents as they are now and move the inlet/outlet even further away. This way the test section will see the planar wave and inlet/outlet effects will be minimized.nWhat working fluid are you using? You may also consider doing Fluent only simulation with MDM to simulate the oscillating wall without systems coupling to simplify troubleshooting / tuning of the modeling approach. Once that Fluent model works per your satisfaction, you can bring back the systems coupling n
