1.	How is the tolerance of convergence decided?(a) Based on stability and consistency(b) Based on efficiency and accuracy(c) Based on efficiency and consistency(d) Based on consistency and accuracyI had been asked this question during an interview.My query is from Discretization Aspects in chapter Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics
Answer» The correct CHOICE is (b) BASED on efficiency and accuracy Easiest explanation: In practical, the results of TWO iterations does not exactly match with each other. The iterations are STOPPED when the solution REACHES some acceptable tolerance. This tolerance is decided in a way that it affects neither the accuracy of the solution nor its efficiency.
