Help with flagging a component for magnetic force calc

[ProtoformX]

I'm modeling a piece of iron in a gap between 2 magnets. I've meshed the iron, magnets, and air, but when I try to flag the iron for force calcs, I get an error:


"Some of the elements (Material 2 ) surrounding the part do not correspond to free space. No force boundary conditions applied for component HUB."


Now, the region surrounding the iron is meshed air with permeability 1, but it is a thin region, about 3mm thick. Why can't I flag this??

Don't understand what you mean by "flag".

In running a magneto-structural analysis, you can flag a magnetic object for force/torque calculations due to the magentic effects. I'm running this in Ansys 9 if it helps.
