Steady and Transient Simulations

Hi

I am trying to run KDV equation (from PDE model library) in steady state. What I did is to change transient matrix (da = 0) and change the solver from unsteady to steady. However, it gives convergence problem. I have many other examples in which I am getting the same problem.

Does anybody know, why the solution does not converge when converting an unsteady (PDE) problem to steady state simulations?

Attached are both (steady) and unsteady models from library.

regards
