Hi guys thanks for all the hin
Hi guys thanks for all the hints you gave me,now i can run rhoSimpleFoam solver and it gives good results, but now i have a new problem.
I'm triyng to test OpenFoam comparing the results it gives in naca0012 profile analisys, i need to calculate lift and drag coefficients but for the drag coefficient it always gives me zero. When i run the application it needs transport properties so i insert the file in the constant directory maybe i need to specify some more files? So i decided to visualize stressComponents but when i run this application it says that there is a dimensional difference between the two members of the equation. Someone can give me some hints? |
Probably the liftDrag app does
Probably the liftDrag app does not pick up your reference length and area correctly. You might need to have a look at the application itself and change its calculation.

I Mattijs i looked at the appl
I Mattijs i looked at the application and i saw that if i calculate the value
(pressureCoeff + viscousCoeff) & flowDirection) two times before the return it gives a drag coefficient different from zero(I don't know if it is good or not but it's a value). otherwise it gives a value that seems to be casual |
