Im creating a mesh for a fixed wing UAV, after importing the CAD geometry, preparing it and creating an enclosure, creating the named selection and going to the fluent mesher, I create the surface mesh and I get the message that my geometry consists of 1 fluid/solid regions, and 1 VOID. Im pretty sure I should only have 1 fluid region and I know I can describe the geometry later to make sure that its only fluid however, is this something to worry about?.
