Question

What does elliptic grid generation mean?

(a) Grids generated for elliptic equations

(b) Grids transformed with elliptic equations

(c) The computational domain is elliptic

(d) The object under consideration is elliptic

The question was asked in unit test.

Query is from Discretization Aspects topic in section Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer 1

Correct answer is (b) Grids transformed with elliptic equations

The best explanation: The one-to-one transformation of the coordinates in the physical domain to the coordinates in the computational domain is done using elliptic equations. It has nothing to do with elliptic nature of the governing equations.
