Is it possible to extract lift and drag curve from Ansys fluent?
 

Hey! I am currently working on flow analysis over 2D airfoil in Fluent ansys... I am new in this programme so after a day of hard work I managed to make the simulation according to the youtube video even with changes of AOA... Now I would like to somehow extract lift, drag and and moment curve, or at least first 2. Does anyone know, if it is possible and how? or any fine tutorial would also nice. Thank you for you answers.

Take a look at the "Reports" section in the outline tree. You'll find both forces and moment calculations are available. Its as easy as choosing your surface and the appropriate direction vector to meet you criteria.

Hello,
Thank you for your answer... I tried it but it didnt work.. It made just a horizontal line when I tried lift coefficient :/

Hello, in the end I managed to did a bit differently via "reference frames" the lift curve looks fine now.... I have just small problem, that for example on lift curve, the paramaters of lift coefficient range from 1000 to 6000 and I guess it shoud be form 0 to max 1,5.... do you know why is this happening?

it took 3 sec

Hello, thank you for your answer Alexander, I checked youtube and google already, the problem with the video is that it gives you just one parameter of the drag/lift... I am working on rotating airfoil simulation, I created 2 interface zones, one is the fluid, and the other one is rotating(inside is the airfoil as the rotating wall) to get a simulation with rotating airfoil (a.k.a in different AOA)...so to do it like this would take hours, one by one so I would be able to make a lift curve from it..

Hi, did you get the method? I`m interested to know as well. I`m also working on this and couldn`t get the value calculated correctly.
