Hello, 


The highlighted face may be the problem. From image it looks like it is a single curved surface. Can you please open geometry in SpaceClaim. Then split this face into more no. of faces, may be 3 or 4 faces. You can use Design -- Split command. Then check the geometry by selecting bodies in tree -- right click -- check geometry.
