Hi all!
I know how to calculate the volume of the first order tetrahedron.
But in the case of second order tetrahedra creating by gmsh for my 
complicated geometry (see one of these tetrahedra
http://saveimg.ru/show-image.php?id=0971dc74b46b676f549960aebeae3e4b) I 
encountered a problem of finding the right volume of the tetrahedron.

Can anybody help me?

Thanks
