(b) Global index has a single index and local index has multiple indices

(c) Both local and global indices have a single index

(d) Both local and global indices have multiple indices

I had been asked this question in quiz.

This interesting question is from FVM topic in section Finite Volume Methods of Computational Fluid Dynamics

Answer 1

The correct answer is (b) Global index has a single index and local index has multiple indices

Easiest explanation: Local indexing is the indexing of elements around a particular cell. It has to mention the direction also. So, it involves multiple indexing. Global indexing is just a single number representing a cell or element.
