I drew a flying wing in Solidworks 2008 to test the lift and drag, but when I click at the flow simulation, it said that I haven't close holes and spaces in my model although I didn't draw any hole.
Does anybody have idea to fix this? I have to test the lift and the drag of this model
check your surfaces.. It sounds like some of them aren't joined.
Just when you thought you had it all figured out, all hell breaks loose..
