Question

I know the value of the flow variable at two points. In which of these cases, is it easy for me to calculate the flow variable at a point between these two?

(a) Three-dimensional FVM

(b) Two-dimensional FVM

(c) One-dimensional FVM

(d) Two-dimensional FDM

I have been asked this question in quiz.

The query is from The Geometry of FVM Elements topic in portion Finite Volume Methods of Computational Fluid Dynamics

Answer 1

Right choice is (c) One-dimensional FVM

For explanation I would say: If the values at two points are known, in the one-dimensional case, it is easy to find the values at any other point. In the two-dimensional and three-dimensional cases, they pose complication to the calculation.
