Question

Vertex connectivity is important while __________

(a) solving the discretized equation

(b) discretizing

(c) post-processing

(d) pre-processing

I got this question in semester exam.

I want to ask this question from Numerical Methods in portion Numerical Methods of Computational Fluid Dynamics

Answer 1

The correct answer is (c) post-processing

For explanation I would say: Vertex connectivity is important for post-processing especially while computing gradients. Vertex connectivity generally contains information like the elements and faces sharing that vertex.
