Line Integral on topology optimization?

Hello all!
I have conducted a small experiment using topology optimization in conjunction with the heat transfer in solids package. The resulting geometry is rather complex. I am now trying to compare it to conventional designs that exist for the problem I am looking at, and I need some information about the surface area / line length where heat transport can take place.
In the conventional designs, I can select a line integral in the derived vales section, put in 1, select all boundaries and comsol will return the total length. How do I do this with a topology optimized mesh?
Essentially, I have a structure, with a output material volume of 1, surrounded by output material volume 0. How do I return its "circumference"?
Thanks so much for any help! Hope my problem became clear, again thank you! Finn

That is probably very tricky. If you export the final topopt contour you can get the information, but I am not sure you can get that information while solving.

Create a Filter data set that selects the volume containing material, and select it in a Surface Integration node.
