For small grid sizes, convergence is related to _________(a) truncation error(b) stability(c) consistency(d) boundednessThe question was asked by my college director while I was bunking the class.My query is from Discretization Aspects in portion Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer»

Correct option is (a) truncation error

For EXPLANATION I WOULD say: When the grid sizes are sufficiently small, convergence is related to truncation error. The rate of convergence is governed by the ORDER of principal truncation error COMPONENT which is used to APPROXIMATE the partial differential equations.
