[OpenFOAM] Plot skin friction coefficient on a airfoil

dinonettis · September 5, 2008, 11:37

Hi foamers,

could somebody please tell me, how can I plot the Cf (obtained by means of the calculator filter) on a wing profile in paraFoam??
alternatively how can I write the result I want (Cf) in a text file together with the relative point coordinate??
thank you in advance.

any help is well-accepted..........

anyway I've asked for the Cf since I need it, but generally speking, how can I plot any variable trend on a specific boundary??
thanks again

Hi, I have seen your problem, and I want to know if you have solved it, because my problem seems similar.
I have created a new variable with the filter "calculator" to get the mass flow in a surface using "Integrate variables", and now I want to plot this variable versus time. What can I do to get it?
Thanks.
