Sorry I am looking in the manual and list archives and I still don't
understand...

Can you tell me if the default behaviour of gmsh is such that mesh
element normals are opposite of the surface normals?  Am using version
2.0.8.

E.g., when I mesh the following .geo, the element normals are opposite
of the surface normal...


Point(1) = {0,0,0,0.1};
Point(2) = {1,0,0,0.1};
Point(3) = {0,1,0,0.1};
Line(1) = {1,2};
Line(2) = {2,3};
Line(3) = {3,1};
Line Loop(4) = {1,2,3};
Plane Surface(5) = {4};



Thanks,


--John
