Question

What is added as a source term in the deferred correction method?

(a) Difference between the high-resolution and the upwind schemes

(b) Constants in the high-resolution schemes

(c) Constants in the upwind schemes

(d) Difference between the downwind and the upwind schemes

This question was posed to me by my school teacher while I was bunking the class.

I'm obligated to ask this question of Deferred Correction for High-Resolution Schemes topic in chapter High Resolution Schemes of Computational Fluid Dynamics

Answer 1

Correct choice is (a) Difference between the high-resolution and the upwind schemes

The explanation is: The source term of the given flow problem is considered. In addition to this, a source term is added in the deferred correction method which is equal to the difference between the high-resolution scheme and the upwind scheme.
