Consistency is defined when the discretization error approaches __________(a) infinity(b) 1(c) 0(d) -1The question was asked in an interview.I'm obligated to ask this question of Discretization Aspects topic in portion Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics

Answer»

Correct choice is (C) 0

For explanation I WOULD say: CONSISTENCY is defined when the time step or grid spacing approaches 0. When this happens the discretization ERROR becomes zero. When discretization error is zero, it means that the solution matches with the analytical solution.
