Question

What is the advantage of the staggered grid arrangement?

(a) Helps to avoid stability problems

(b) Helps to avoid convergence and consistency problems

(c) Helps to avoid convergence problems and oscillations

(d) Helps to avoid boundedness problems and oscillations

I got this question during an online exam.

The origin of the question is Incompressible Flows in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Answer 1

Correct choice is (c) Helps to avoid convergence problems and oscillations

For explanation: The biggest advantage of the staggered grid arrangement is the coupling of pressure and velocities. It also helps to avoid convergence problems and oscillations in pressure and velocity fields.
