Hello Rob. Thank you again for your help. I did some checking and the original cad was created in MM from Rhino 7. It was imported to spaceclaim in MM and volume extracted. It was meshed in fluent with meshing with changed it to Meters. So based on your point I need to open the scale tool in fluent solver and change the units back to mm since the mesh was in m so its uniform all the way. This could be the issue based on your helpful feedback. Just wanted to double check if this is correct. Thank you for your help Rob.
