Ce travail consiste à adapter l'intégrale triple au calcul du flux en 3d par le théorème de la divergence : (M_x + N_y + P_z)
Exemple de sortie écran :
Use the divergence theorem to find,
the flux of F through S.
// ///

|| F.n dS = ||| div F dV

// ///
S Q
If F = Mi + Nj + Pk
/// ///
||| |||
||| div F dV = ||| M_x + N_y + P_z dV
||| |||
/// ///
