Hello everybody, I ask you for some help with something I don't really understand about my simulation results.
I am simulating a body that has a cylindrical shape with some circular round sections on the borders of the cylinder. Such as this I show you:March 17, 2022 at 11:56 pmSurya DebAnsys EmployeeHello,
Please check the influence of reference pressure in the force calculations.
You can check the link below for more information

Something was not going right with Absolute Pressure either, the calculated force had the opposite sign as expected, but actually, I tried with the Static Pressure, although there is no such a variable with this exact name I tried with the Pressure variable, which I imagine is equivalent, in this way, the result matches perfectly with the expected result.
I will assume those results as valid.

March 29, 2022 at 11:50 amgerardsoldevilla99SubscriberThank you, I can't access this file for some reason, do you have any other way to share me, with a screenshot or sth, by the way, my reference pressure is kind of fixed in my problem, I am simulation an airplane at cruise altitude of FL490, so I set the reference pressure as 20kPa, and I don't think there's a reliable way of doing that.
Could you share with me the document you talk about, thank you anyway
