$$$$ DBIT NOTICE CHAT 11/09/12 21:15:43 7124 DATE 11/09/12 Operateur DBIT Voir aussi : -------------- Q = DBIT MODE1 U <'IMPR'>; Q1 Q2 = DBIT MODE1 U 'ALGE' <'IMPR'>; Description : _____________ Computes the flux of a vector through a 2D line or a 3D surface. The result is a FLOTTANT, sum of the fluxes (global flow). If 'ALGE' is mentioned, the fluxes in the normal direction and in the opposite one are given (Q1 et Q2). The surface or the line may be closed. Types of elements : in 2D : SEG2 or SEG3 in 3D : TRI3, QUA4, TRI7 or QUA9. In 2D axisymmetrical, the surface considered is the one generated by the 2pi radians rotation of the line. The normal used for the calculation is that defined implicitely by the orientation of the elements of the mesh object that stands for the boundary (trigonometric convention). So it is strongly recommended that the user takes care of the proper orientation of these elements during the creation of the mesh. Contents : __________ MODE1 : modeled structure (MMODEL type) 'NAVIER_STOKES'. U : CHPOINT (VECT SOMMET) the flow of which is calculated. Q : result. Note : ______ The operator prints the global flow both in the direction of the normal and in the opposite direction if 'IMPR' mentioned.
