Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have two 2D functions (surfaces), s1(x,y) and s2(x,y) defined

via Interpolation. They intersect forming an intersection seam (which is a line).

I can plot both functions using Plot3D and I can also plot the seam on the same

3D plot by means of the MeshFunctions option. The comand I use reads the following:

Plot3D[{s1[R, a], s2[R, a]}, {R, 2.62, 3.19}, {a, 1.36, 1.78},MeshFunctions->{(s1[#1, #2]-s2[#1, #2])&},Mesh->{{0}},MeshStyle->{Red,Thick}]

But waht I would like also to plot is the intersection seamon the contour

plots of S1 and S2. I mean I can plot a contour plot of S1 or S2 (using ContourPlot)

but I don't know how to add the seam to the contour plot.

I will very appreciate any hint/instructions how to do that.

Many thanks!
