Using "jump" on an unfitted mesh

Hi everyone,

I'm working on a  diffusion equation with discontinuous diffusion coefficient. I'm using an unfitted mesh which the interface is not aligned the mesh facet. And I did not do a DG method.
My question is how to use the "jump" function to do this integration? Since all the examples I can find is focused on the jump across a facet. How to do this "jump" in a mesh? Like the image I attached. There is a discontinuous along the red line. How to use "jump" here? Would some one give me some suggestions or examples? Thank you so much.




Best,
Ting

There is a chapter in the FEniCS book, Modeling evolving discontinuities which describes some code to accomplish this task, but I believe the code has ceased to be supported:

for example.
