Question

Which of these diagrams are used to visualize the high-resolution scheme?

(a) Leonard diagram and NVD

(b) Cumulative flow diagram and NVD

(c) Sweby’s diagram and NVD

(d) Cumulative flow diagram and Sweby’s diagram

I have been asked this question in a national level competition.

I need to ask this question from High-Resolution Schemes in portion High Resolution Schemes of Computational Fluid Dynamics

Answer 1

Correct choice is (c) Sweby’s diagram and NVD

The explanation: The NVD (Normalized Variable Diagram) and Sweby’s diagram are used for visualizing the high-resolution schemes in the NVF and TVD formulation respectively. They can be used to visualize the flux limiters.
