Steady-state error CFL dependence

I have a question about solution error dependence on iteration "time" step or CFL number. I see DeltaT in the modified equations of some algorithms, but intuitively (to me anyway), for a steady-state flow shouldn't the result be independent of DeltaT?

Hi,
For a Steady state problem your converged solution does not depends on the delta t (CFL) you choose, provided your code converges with the CFL you use. Steady state solution will be same for all CFL's if your solution has converged. Thanks, Vinayender. |
