RE: Reference Pressure dilemma -- CFD Online Discussion Forums

CFD USER Guest Posts: n/a	Hello, I am trying to calculate Lift and drag forces over a body In the first case I left reference pressure as zero and outlet pressure at 1atm relative static my lift value was about 1642N In the second case I changed my reference pressure to 1atm and outlet pressure to 0static pressure averaged over whole outlet. Now I am getting a lift of about 750N. I am really confused about this difference and I will really appreicate your insights. Thanks, CFDuser.
