Analysis of Solution Stability in a 2D Heat conduction problem

ANALYSIS OF NUMERICAL STABILITY OF VARIOUS ITERATIVE SOLVERS FOR TRANSIENT 2D HEAT CONDUCTION: [Part: 3/3] INTRODUCTION: The criterion of stability of a numerical scheme is determined by the way the errors propagate while the solution moves from one time-step to the next in case of a transient solver. While solving governing…
