I need help with an unusual airfoil design!!
 

Hello, I have run an OpenFOAM simulation with a standard airfoil and have some fantastic results. As soon as I change the airfoil into an unusual saw toothed design I get a heap of solution singularities and OpenFOAM spits the dummy. Does anyone know how to solve this? I have spent the past 2 days constantly fiddling with it to no avail.
