Hi,


I am trying to model aluminum louvers as opening wall that has 40% opening ( partially opened), is there an easy way to reduce the opening percentage. I tried playing with the loss factor but am not able to tune it and it gives non-steady solution sometimes.


thanks

What is this 40% opening going to do to the rest of the domain? Raise the pressure? Then raise the pressure of your outlet boundary condition accordingly.
