Hi all,

I have two vector field J1 and J2, in 3D space (x,y,z) and calculated
at some discrete points (extracted in a txt file from comsol.

I need to volume integrate the
triple_integration of (J1 dot J2), which is expressed as

triple_integration ( J1(x)*J2(x) + J1(y)*J2(y) + J1(z)*J2(z) ).


I have found that http://www-users.math.umd.edu/~jmr/241/tripleint.html
, but in my case, I have no analytically expression of the funstion.
I guess I could interpolate using TriScatinterp, but is any other way
to do that?
