Floworks boolean operation problem


New member
Hi guys
I'm currently attempting an external flow analysis of a model of a single seater race car I created in solidworks. The problem I have is that everytime I ask Solidworks to check the geometry (with the check for invalid contacts box ticked) it comes up saying that one of the parts might produce an invalid contact if used with a boolean operation (error code 547). Everytime I try and fix the problem in one part it simply passes the error onto another part.:confused: Does anyone know what this error message means, what could be causing it, or what I could do to fix it?
