Hi,

Can you tell me how to set up simpleFoam to run with adjustTimeStep ?

I checked the code and compared it with rhoPsonic foam. but the step where the max courant no is computed has a variable phiV that is incompatible with simpleFoam. I would really like to run simpleFoam with adjustTimeStep.

Regards,

prasad.

Default You can't. For a steady solver

You can't. For a steady solver the concept time doesn't make sense. Think of time for simpleFoam as an "iteration counter". Adjusting the time-step wouldn't change anything
