The aim for this port is to find incompressible velocity field FITS satisfying on every ellipsoidal surface of constant '2 . The velocity field book for must be of the form (Fx = Dax(2 ) x + Day (2 ) 4+ Dxz()z. where D (2 ) is a symmetric matrice Fy = Dyx (2 ) x + Day (2) y + Dyz (2) 8. of order 2 . Fz = DEX( 2) x + Dzyaly + Dza)z. Co. Find the divergence V. FCB)
