Steady state vs unsteady analysis

Steady state analysis is independent of time marching,temperature gradient doesnot changes with respect to time,whrereas in unsteady state involves time marching solution,temperature gradient changes with respect to time.

Steady state provides solution at a faster rate as compare to transient state both implicit and explicit method.

In both states,convergence rate is faster with respect to time and iteration in SOR method than Gauss Seidal and Jacobi Method.

In unsteady state,comparing implicit and explicit method,explicit method takes lesser amount of iterations compare to implicit method.
