Question

Which of these establish a one-to-one relationship between two elements?

(a) Face

(b) Node

(c) Vertex

(d) Element

This question was posed to me in my homework.

I would like to ask this question from Numerical Methods topic in section Numerical Methods of Computational Fluid Dynamics

Answer 1

The correct answer is (a) Face

To explain: A one-to-one relationship is given by the faces of a mesh. One face is shared by two elements. It usually contains information about the fluxes flowing between those elements.
