Which is the order of accuracy used for?(a) To quantify the rate of convergence(b) To find the error(c) To find the stability(d) To find the consistencyThis question was addressed to me during an interview.My query is from Finite Volume Methods topic in chapter Finite Volume Methods of Computational Fluid Dynamics

Answer» CORRECT option is (a) To quantify the rate of convergence

To elaborate: The order of accuracy of a numerical method is USED to quantify the rate of convergence of the approximation. This can be applied to both the finite difference and the finite VOLUME METHODS.
