Question

Which of these is correct regarding the minimum correction approach?

(a) The non-orthogonal correction is kept as small as possible

(b) The non-orthogonal correction is kept as large as possible

(c) The surface vector is kept as small as possible

(d) The surface vector is kept as large as possible

I have been asked this question in final exam.

This interesting question is from Diffusion Problem topic in portion Diffusion Problem of Computational Fluid Dynamics

Answer 1

The correct answer is (a) The non-orthogonal correction is kept as small as possible

The best explanation: In the minimum correction approach, the decomposition of the surface vector is done in a way that the non-orthogonal correction is as small as possible, thus making the \(\vec{E_f} \,and\, the\, \vec{T_f}\) orthogonal.
