Hello,

How to draw camber line of an airfoil in Gambit. I have only coordinates of the upper and lower surfaces of the airfoil.

You just bring your coord to note pad=>> make matrix of its coord ==> from left to right is X-coord, Y-coord, Z-coord. Don't forget to initiate them for GAMBIT==> write the number of coord and then the number of your matrix (it will be the number of line you have).
here is the example

36 is number of point you have
1 is number of matrix you have (it can be number of edge)

then save it to your directory ==> run GAMBIT ==> click FILE ==> chose IMPORT==>ICEM INPUT==> chose file you have saved==>on geometri to create select edge==> OK.
You will have airfoil !!!
Try it!!!
