[SOLVED] Get shared nodes in solids with different mesh elements

Hello Everyone.
I am modeling a pipeline (radius=30 cm) buried in soil, and I am using DKT elements for the pipeline itself.
however, the modeling of soil is a bit more complex: I have divided the soil into a cylinder (radius=120 cm) surrounding the pipeline with hexahedron elements, and the rest of the soil is modeled with NETgen 1D-2D-3D elements. my problem is that I don't know how to define the nodes of NETgen mesh to be the same as the hexahedron cylinder. Is there actually a way to do that?
I would really appreciate it if someone could help.
This is my first post here, up until now I have found the answers to all of my question in this forum with searching but I did not find anything that could help me with this problem.

P.S: I attached a picture of the actual mesh. it is not the final and precise mesh, it is just to show what I mean.

Hello,
there are similar posts in the salome-platform's forum. It's a bit tricky, you must add 2 sub-meshes in order to apply 2 different algorithms:
