I'm trying to learn gmsh with a simple airfoil problem but it keeps crashing on
my geometry. I don't see why it should have a problem, so I'm looking for
suggestions. By the way, I know I can do an extrude to get the 3rd dimension
for this case, but for more complex cases I want to set it up this way. Thanks
for any guidance you can give
