Hello! I am trying to simulate the flow around a racecar. When I insert the geometry everything seems ok, but when i make the enclosure, the surface can not be representated 100% with all its curves.
1)Why is that happening? Will it have an impact on the whole process?
2) During meshing it indicates 2 problems: " Illegal triangles were found after surface tesselation. There could be a problem with the CAD geometry. Trying to proceed anyway." and
“The tesselated surface is not closed. There could be a problem with the CAD geometry (such as self-intersections). Please inspect your geometry. Trying to proceed anyway.” and also an error about the quantity of mesh elements
How could I fix these problems in this particular geometry?
