Hey, guys, I got a problem.
aerodynamic (but in my time the cfd moved the first steps) I want to use ansys cfx to calculate portance and resistance of a complete wing.
My problem is that the results vary depending on the volume of fluid I use (i.e. if the fluid is a cube of 100 mt of edge I have a different result than a frame cylinder of diameter 100m).
Moreover, with the cylindrical volume I obtain values equal to those expected for the portance, double for the resistance. Why?
Thank you.
