Hello everybody.
I'm new to fluent and I have some problems in ansys meshing with a perforated jet plate in a channel .I want to evaluate heat transfer of my working fluid (air) in a channel (air heater) and I use jet plate impingement on a heated surface(absorber).I used boolean operation and substracted the perforaed plate and I preserved It. After that in ansys meshing I enter contact manually but it takes a long time and I recieved the error that some of your surace aren't in appropriate direction but when I didn't do it manually ,I 'v got problems in taking all the surfaces (surface in the holes that have interface with fluid domain) and in fluent I have problems in coupling interface couplings.I attached my geometry images.
Thanks in advance.
