I ended up making another, more refined mesh, by adding a second prism layer. But I switched the tube mesh to polyhedral instead of the thin mesher so that I could: 1) mesh the whole thing in...

Adding the prism layer did drop the surface temperature of the cylinder by about 15 K so far, but the case is not yet converged, so I'm not sure what the final value will be. It does appear that it...

Thanks, I'm increasing the refinement now. Also, I noticed that meshes of the solid and fluid are not conformal. Will this impact accuracy as well? If so, how would I make the meshes conformal? I...

I mis-spoke earlier when I said I was expecting a linear temperature profile in the cylinder. Actually, it is cylindrical geometry, but it is a tube rather than a solid cylinder. I would expect a...

No, no prism layer. I have experimental temperatures to compare my predictions to and it seems like I'm overpricticing all of the measurements by a good 20 K everywhere. Do you think increasing the...

Temperature of solid/fluid interface inconsistent

I have a fluid flowing around a solid cylinder. The cylinder has a power applied to it. I setup an arbitrary probe using a VTK file to get the temperature on the surface of this cylinder at many...
