Question

The numerical solution results in certain amount of truncation error.

(a) True

(b) False

I got this question by my school principal while I was bunking the class.

This key question is from Philosophy of Method of Characteristics in section Numerical Techniques for Steady Supersonic Flow of Aerodynamics

Answer 1

The correct option is (a) True

Explanation: In an ideal case, with infinite grid points, the numerical solution is exact. But in real life, the number of grid point for computing the flow field properties is finite and thus, the higher order terms are usually neglected causing ‘truncation error’.
