 April 2, 2013, 06:47 Surface-plane intersection curve plot #1 Senior Member   Francisco Join Date: Mar 2012 Location: Spain Posts: 273 Rep Power: 14 Hi everyone! I'm running a 3D simulation of flow around a cylindrical wing. I want to plot Cp along a section of this cylinder so I would like to chose the intersection of a normal plane and the wing surface to plot results on the resulting curve. How can I do that? Is it possible to calculate 2D drag and lift coefficient directly on this curve? Thanks a lot!

What I need is Cp distribution (or any other variable such as y+, y*, etc.) in the intersection of the plane (with contours) and the surface (mesh). See picture.

Thanks!

 April 4, 2013, 07:09 Solved with iso-surface. #3 Senior Member   Francisco Join Date: Mar 2012 Location: Spain Posts: 273 Rep Power: 14 Solved! If anyone face this problem here it is the solution. It's made by selecting iso-surface, variable mesh/coordinate y (for example) select a constant value for this. Choose the surface you want to intersect and you get a curve on your surface of y=constant. Shamoon Jamshed, Mazze[ITA], LuckyTran and 9 others like this.

Please explain this in more detail. I didn`t understand about 'the surface you want to intersect'

Thanks. I got it.
