1.	In the boundary faces, the normal vector points _____________(a) to the owner element(b) outside the domain(c) in the direction of the flux(d) in the direction opposite to the fluxThe question was posed to me in my homework.I want to ask this question from Numerical Methods topic in portion Numerical Methods of Computational Fluid Dynamics
Answer» CORRECT choice is (b) OUTSIDE the domain Explanation: The boundary FACES bound only ONE element and they do not have any neighbouring elements. So, the owner elements in the boundaries have their faces with the normal VECTORS pointing outside the domain.
