Question

Conservation of the system leaves a limitation to the __________

(a) stability

(b) solution error

(c) convergence

(d) boundedness

I had been asked this question during an interview for a job.

This intriguing question comes from Discretization Aspects in section Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer 1

Right choice is (b) solution error

For explanation: If the conservation of mass, momentum and energy are ensured, the error can only interchange the values at different nodes. The overall system will not be erroneous. So, the solution error is a way decreased by the conservativeness of a system.
