Cut "curve" 3D

Hi

I've solved a coupled velocity and temperature field in an evaporating liquid. The liquid interface is not flat. To compare with my experimental results, I need to extract the data along a diagonal curve at the interface (See the attached file).

Does comsol have something similar to cut line 3D to obtain a curve on the non flat surfaces?

Amin,

Thanks Lesse.
But I forgot to note that I don't have the parametric equation of the curved surface. Is there any other way?
I think I have to repeat the simulation having the curve already defined on the surface in the geometry section.

Hi Amin,
You can modify the geometry to add the line you want (and in your case it looks like that line can be generated by intersecting the geometry with a block), then use "Update Solution" in your Study.
Using "Update Solution", as opposed to "Compute", avoids recomputing the solution.
Best,
Jeff

It worked.
(I generated the curve using "partition faces and a workplane")
Thank you.
