Question

When the source term varies highly, which of these properties is affected?

(a) Consistency

(b) Boundedness

(c) Stability

(d) Rate of convergence

The question was asked during an interview for a job.

The origin of the question is Source Term Discretization in chapter Discretization of the Source Term & Relaxation of Computational Fluid Dynamics

Answer 1

The correct option is (d) Rate of convergence

For explanation I would say: When the source term is a constant or small, the analysis is not affected by it. But, when the variation of the source term is large, the rate of convergence of the numerical process is greatly affected.
