Numerical schemes for solving Unsteady heat conduction equation

I have used both the Euler scheme and RK-4 scheme for solving 2d - unsteady heat conduction equation. The results showed that Euler scheme converged to steady-state a bit faster than the RK-4 scheme. Is this result correct?

Hey @rraj111998 and sorry for the delay in my response!

From numerical point of view, Euler should be faster but less accurate. Hope that helps! Also note that we do not have RK for CFD (in case you thought about it) :slight_smile:
