A general question:

I notice that WB uses different material numbers in the background for different bodies in a multibody part.
It may be the same material properties and sharing the same mesh, but ANSYS treats it as a material boundary.

The impact I notice is that unless you turn on stress averaging in the results (everytime) it will report unaveraged stress at the false material boundaries.

Is this just sort of a 'known' issue or is there a standard workaround that eliminates this?

Typically the error is small and the stress will just come out a little higher but it seems fundamentally wrong. Not to mention a bit annoying :)

Thanks,
