Question

Which of these properties are balanced by using adaptive grids?

(a) Accuracy and convergence

(b) Efficiency and stability

(c) Accuracy and stability

(d) Accuracy and efficiency

This question was posed to me in examination.

This key question is from Discretization Aspects topic in portion Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer 1

Right choice is (d) Accuracy and efficiency

The explanation: By automatically generating the grid points, the places without much variation are given fewer grids and the places with high variation are given more grids. This helps in maintaining a balance between efficiency of the solution and accuracy of the answers.
