Question

Structured grids give ____________ and need ____________

(a) no access to elements, less memory for storage

(b) easy access to elements, less memory for storage

(c) easy access to elements, more memory for storage

(d) no access to elements, more memory for storage

The question was posed to me during an interview for a job.

This question is from FVM topic in section Finite Volume Methods of Computational Fluid Dynamics

Answer 1

The correct choice is (b) easy access to elements, less memory for storage

To explain: Structured grids have properly ordered cells. So, it is easy to access their elements or grid points. As access is easy, it is easy to store the values also in memory. So, less memory is required.
