Thomas,
Leila found my problem. No need to look further.

Bill

Hello Bill,

as far as I can tell, the RegularSphereMeshSource produces a correct 
mesh. I use it for the simplex mesh deformation model and never 
experienced a problem.

Could you send me your algorithm code and I take a short look at it to 
check how you are iterating over the triangles for computing the surface 
area / volume of the simplex mesh.


   Regards,

     Thomas
