Excluding surface elements from Volume Set of the grain.

[AlexZait]

Dear experts,

I use example "Gmesh Example Pipeline" from SimulationIO. After openning .inp file in Abaqus I see some Surfaces and Volumes in Sets - it is good. But like I found out the elements which belongs to, for example, set Surface 1 in the same time belongs to set Volume 1. What to do in dream3d to separate or exclude Surface elements from Volume elements, because I need to apply them different mat. properties?

P.S. I tried to change properties in "Find Feature Nieghbors", but didn't get any positive results.
