Question

Transportiveness has an influence on _________

(a) the discretization scheme

(b) the solution method for an algebraic system of equations

(c) the mathematical model

(d) the iterative scheme

I had been asked this question in semester exam.

The above asked question is from Discretization Aspects in section Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer 1

The correct answer is:

(a) the discretization scheme

Transportiveness refers to the ability of a numerical method to accurately capture the transport of quantities like mass, momentum, and energy across the grid. This property directly affects the discretization scheme, as a well-designed discretization scheme should correctly represent the transport of variables and their interactions within the computational domain. Discretization schemes that preserve transportiveness ensure that the numerical solution behaves consistently with the physical model.
