Hi I am using CFX5.5 to create a complex multi element airfoil. So far I've created a B-rep solid but when l came to mesh my model it came up with a warning that said that there were internal angles to small. I was hopping if any one could tell me how to fix this problem without going back and changing the solid.

You could try the AFI surface mesher instead of the default Delauney surface mesher. The time to create a mesh will increase a little, but the mesh quality might improve considerably.

If it does not help, you can try to refit the surfaces that are troublesome. But I guess you have to delete the old solid and create a new one. But is that a real problem??

Ivan, where are the pooly defined elements on your airfoil ? Have you tried applying mesh controls in those regions ?? Dave
