Lift force in UDF
 

Hi, I want to use lift force to calculate the displacement of the body using Finite different method.
Is any body know how to access to lift coefficient or lift force value in fluent? I know how to monitor and write the Cl & Cd value, but I dont know how to access to lift force in UDF.

Thanks for your help

hello
you must go to the results tab , then reports, then forces, and now according to your axis condition choose the direction of normal to your wing ( lift ) and then go. your desired lift coefficient now can be viewed in last the column of the last row.
good luck.
