How to plot Lift and Drag Coefficients using tecplot 360
Hello, I can calculate the integral values of forces and momentums over an airfoil surface but I can't obtain a plot from it. In the x variable option I can't select x coordinate. Instead the index "i" is selected and I don't see any curves.

Hi Rui,
which solver are you using? |
Hi giuli@, I'm using the simpleFoam solver, for incompressible steady flow over an airfoil.

I'm not really into OF;
what I remember about plotting Cl in Tecplot360 with Fluent data is that I had to extract the variables I wanted in Fluent itself (saved in .xy files), and than import these and make xy plots in Tecplot. Try to find the way of telling openfoam to get the Cl, Cd along the desired section for all the X values (what I was doing in Fluent), Then, make a ".dat" file with this header: VARIABLES="x","Cl","Cd" and under, in columns, the corresponding values extracted. Sorry but it's all I can think now :-/ |
Errata corrige: I was plotting velocities components (it doesn't make sense to plot Cl and Cd along x since these are integral values)

Rui,
