What does this symbol mean?

Motor

Hi,

When I volume mesh my body, I get that a volume gets this symbol after meshing. Could someone understand me what it means? All other bodies get a 3d shape next to their name, but only the air of my motor (cavity1) gets this blue 2d shape next to its name.

Hello,

In this case, the element displayed by Simlab for this body is a sheet. Could you share the Simlab model? It's strange to get a volumetric mesh on a body of type sheet.

Thank you.
