Homework Statement:: time step must be greater than stability criterion
Relevant Equations:: stability criterion= h^2/4 x alpha
Hello. I have had to do 2 MATLAB codes based on the 2D Heat diffusion equation using the Explicit Finite Method. In those codes, the time step must be greater or equal to the stability criterion. I do not understand the relationship between the time step and the stability criterion or why the time step must be equal to the stability criterion.
