Hi everybody.

When I read the mesh file with Fluent two errors appear:

1)
"Building...
mesh
auto partitioning mesh by Principal Axes
Warning: Partition method "Metis" is not allowed for
autopartitioning for cases with non conformal
interfaces before the interfaces are defined
and intersected, use "Principal Axes" instead.
You may use the "Metis" partition method
after the case is read in and the interfaces
are intersected.,"

2) Note: zone-surface: cannot create surface from sliding interface zone.
Creating empty surface.


Since there is the rotating domain of the water wheel I have created interfaces. Despite these errors, the model reaches convergence, but the calculated torque is wrong.

Anybody can help me? The previous two errors are negligible or not?

Thank you

hey!

about 1st question! I've never encountered this problem before! but maybe rotation axis is reason of problem!

about 2nd question
this isn't an error! only a warning! fluent says this warning because you're using mesh interface! In this case there is no problem...

I encountered the first error message you got recently. In DesignModeler, I had 3 bodies grouped into a single part. When I broke the 3 bodies into 3 parts, the warning went away.
