I am trying to visualize flow of air through the geometry. I made a bounding box (wind tunnel) and provided inlet velocity and outlet pressure.
While running simulation, this was the error: A multi-region mesh was assigned - this analysis-type requires a single-region mesh.

I found that many others had the same problem but the solutions on those pages didn’t help. Can someone help?
