Stability Analysis
Courant-Friedrichs-Lewy(CFL) number plays an important role in detremining stability of the system. For transient state, when diffusion term is involved,CFL term is defined as CFL=alpha.(dt/dx^2) where alpha is Thermal Diffusivity when dx term is increased by a factor of 2,we need to decrease the value of dt by factor…
