To get to it, you need to run the code long enough so that the solution to the unsteady flow problem you are solving approaches the steady-state solution. You just need to take more time-steps while making sure that time increment ($\Delta t$) satisfies the stability criterion. In the code you provided above, there is a factor of 1/2 missing in the calculation of dt. Is this a typo? | |
