Question

The values of the flow variables at the faces can be calculated by _____________ in a structured grid.

(a) Interpolation

(b) Taylor series

(c) Fourier series

(d) Shape functions

Answer 1

The correct choice is (a) Interpolation

Explanation: As the cells of a structured grid have simple quadrilateral shapes, the values at a cell faces can be easily interpolated using the values of the flow variables at the cell centroids of the two cells sharing that particular face.
