Hi,nYou could simply treat it as a porous media and provide it with some viscous resistance coefficient. This should help you model the flow resistance you would observe physically.nPlease ensure that you have share topology in your domain. This will create the necessary internal face zones between the fluid and the porous regions.nIf your flow is likely turbulent, please look into the Treatment of Turbulence in Porous Media details on the Fluent Users Guide.nKarthikn
