Solver settings for steady state simulation
I have also tried turning warped face gradient correction off but it still diverges in the transient simualtion.
Courant no - 5
when I start the transient sim, after some iterations:

  1. So how do I reduce residuals in steady state, right now its oscialllting somewhere between 1e-3 and 1e-4
    2. How do I prevent this from diverging as shown above in transient sim?
    Thanks
