I used before Star CCM+ and it was no problem for making conformal multibody meshing but I don’t want to use it anymore. With CFMesh+ it’s also possible and I tried it, it works fine! But as I said I want to use opensource programs.
I tried something:
I made a reactionzone (inner pipe) and a pipe which have a bigger diameter at the same point (on XY Plane). Like in this picture:

As I said I made many conformal mesh in my life and knows it’s better to make a differenz between the reactionzone+sweep and the reactionzone. So the result is only the sweep which is around the inner pipe (reactionzone). After I did a bollean operations —> FreeCAD after boolean oprations: https://i.imgur.com/VQwWLWD.png
This is my effort from today after using first time both softwares. I am sure that we can fix the case.
In the last Video (YouTube) the man using two cubes and the one cube 1 (the ground) is conected to the bottom auf Cube 1. Than he said that cube 1 the ground is the fix area and from cube 2 the over bottom is the top.. but what subtle fix and top area in my case?
My desired result: a multibody region where I can define two different physics and the boundary layer to the next region not will be merged. The most conformal mesh tutorial make two geometries one, but I want two separate from each other but where the nodes meet.
Thanks a lot and I hope we will solve this case.
PS: after it works in Salome, I want to try it in GMSH (after partitioned in Salome). Than write a Pythonskript that make all automatically and all in this forum can use it.
But how I can put it on a cylinder and a hole-cylinder who including the first one like in my picture?
Thank you for sharing, that is very nice. Hopefully we can make it easier and more semless in the future.
My opinion is better to use one software, which make one thing good.. for example.. FeaTool can make a grid etc. but not conformal multi body mesh, right?
So our workflow will looks like so:
1. FreeCAD for making the CAD geomtry and set constrains (parameter )
