I continued the experiment and the Cd values are coming up to the expected value now, so that's good news. I will attach a snapshot.nI am, however, a little concerned with the trajectory of Pressure Residual and the overall residual values (k and omega seem stable but are oscillating at a value of around1e-3 and 1e-4). I am using a time step size of 5e-5 right now and I know that the residuals will decrease by decreasing the timestep size but the trajectory remains the same.nI am concerned about the trajectory and oscillation amplitude of Pressure residual.nWhat can be done to make pressure residual to converge? I am not sure if I am just lucky that the Cd values are now stabilizing, even though the pressure is diverging.n
