3D airfoil simulation

[Aron.bauwnes]

Hello,

I am a student and very new to the world of cfd. I am part of a group of students who are making their own gliding plane with included camera and image recognition to fly over disaster sites and look for survivors etc... Anyway, I'm trying to simulate diffent airfoils out of different materials at different aoa to see which wing would have the most lift with the least drag. Now when I change the material the lift does not change at all, does CFD not take material into account when calculating the force that the wind has on my body, or am I just doing something wrong? I can't find much info about this. I'll include my files if that would help any of you. I hope that the files I have provided are sufficient, if they are not please do let me know. 

The boundary conditions I am using is 19m/s velocity in the front 0 pressure in the back, and all others are slip/symmetry

Thanks in advance and please conact me if you need any more info.

I'm assuming you mean the material of the airfoil and not the fluid material around it.  Why do you think that the airfoil material has any affect on the fluid flowing around the geometry?  This program only simulates fluid flow and thermal affects.  It does report forces but does not simulate stress in mechanical parts.

Yes that is what I meant sorry.

I supposed it would take into account how much the part weighs and then subtract that from the forces produced onto the part, but now I realise that is a bit stupid of me to assume. Thanks for your reply. I will manually subtract the weight of the airfoil from the lift.

Thanks for your reply.
