Default skipping zone... (not referenced by grid)

Hi everybody.

I tried to define surfaces inside my control volume in order to get the velocity and the mass flow true those when I post process the data. I did this with Ansys workbench (design modeler) . Everything works fine until I open fluent, I have the following message:skipping zone... (not referenced by grid). So the surfaces are not loaded. My goal was to define those surfaces as interior.

If you have any ideas it would be great, those surfaces have very complex shapes so I cannot generate them with planes with any post processing software.

Thanks,

Louis

My guess is that you have a named selection for the geometry, but your mesh did not form along those internal boundaries (it may have passed thru them). Perhaps because you had a multibody part or your geometry was unioned or something like that.

Go back to the meshing and try to figure out what in your settings is resulting in mesh that ignores the internal walls...

A picture of the mesh with a clip plane cutting thru this boundary might help...
