Thank you for your response.nI have already checked the reference part. I have modified the Area parameter to 0.1 (square cylinder depth (it is a 2D simulation)), the inlet velocity, and the dynamic viscosity parameter as I had defined to match the Re I wanted. I am a little stuck here so I want to get some insights. Thank you. nThe simulation yields the correct answer in the case of a rectangular domain but the answers are weird when I use this circular domain. I am not sure why.n
