How to model a rack of the inlet?
 

Hello,
does anybody know how to model a rack of the inlet, in sense of distributed resistance?
I have seen the Tutorial 10, Ansys CFX Help, but within the converter, a subdomain is added to model a honeycomb structure using a directional loss model, while I have to set a rack with vertical bars.
Any comments and suggestions are higly appreciated!
Thank you and best regards!
