OpenFOAM — TIPS 2

  1. The beauty of the OpenFOAM is, you can change controlDict, fvSchemes and fvSolution on-the-fly.
  2. To change parameters on-the-fly, set runTimeModifiable to yes in the controlDict dictionary.
  3. In case the initial transient is of no interest, the simulation can be started with low Reynolds numbers (high viscosity) and on the go, one can change the value slowly till arriving at the desired value.
  4. If not comfortable with the point 2 or work with high Reynolds numbers, the Euler solver with upwind is suitable for the good initial solution.
  5. One can switch from the first order scheme to the higher order scheme anytime.
