Drawing 2D foil data from 3D simulation
 
Obviously we can use XY plot to plot the pressure distribution on specified wall boundary in 2D cases. However, how can I obtain the same data when my airfoil has a span and is simulated within a 3D solver?

I tried to create a plane normal to the span direction and then do the XY plot. It gives me every nodal data lying on the plane, unfortunately. Is there any way to "intersect" the wall boundary and a particular plane to drain the, for example, 2D data on the wall from a 3D surface?

I think output the data to Tecplot may help~

Yeah, Tecplot and Ensight is probably the most convenient way to do this. I don't understand how could Fluent miss this issue, considering the interpolation of two intersecting planes are somewhat an easy thing, compared to the others...
