Dear GMSH, I generate a 3D tetrahedral mesh. Each tetrahedron is given by 4 coordinates (c0,c1,c2,c3) Can it be guaranteed that the volume of the element, namely det(c1-c0, c2-c0, c3-c0), is always positive?
I am getting negative values, but I am mostly convinced it is due to my code. I just wanted to cross-check. I mean, I can always just take the absolute value, but why waste and extra code if it is already ensured to be positive :) Regards, Aleksejs _______________________________________________ gmsh mailing list [email protected] http://www.geuz.org/mailman/listinfo/gmsh
