Basic model selection question

marco.bianchini · January 23, 2017, 14:55

Hi,

I am switching from the k-epsilon to the k-w model, do I have to delete my solution and start again or can I keep my convergence and just click run? How do I know which model is using?
thank you

No, you can just keep your run and keep going. You may have to change your turbulence BCs depending on how you specified them.

You will see in the text window which equations are being solved.

thank you.

What about if I change BCs while it is running? Do they get updated or do I have to stop, change them, initialize and run?

If you change them while running they will be updated automatically.

I am a bit worried because it keep sayings tke and sdr, as it was doing with the k-epsilon. Is it ok?

If you were running k-epsilon before it should have stated TDR instead of SDR.
