Step-by-Step Tutorial: Homework of Session 4

I get the same strange meshes where the edges of my Fronwing end up in these sharp edges. I tried for nearly 12h now to fix it on my own or with the questions previously asked. The simulation won’t run with this mesh. Has anyone another idea how to fix this? Could it be because the wing intersects the cars body?
