It did work, indeed! I tried turning off/on the weld option but I guess somehow the dynamics didn't like that sort of setup. Thank you for help, Happy.
Is this any helpful ?
The Push Apart is optional.
You can test between old Bullet System and new Soft Body system (old system is faster)
Simulation is faster with the 2nd cell layer deactivated
cells.c4d
there are several ways, even without using volumes there is the spline modifier, otherwise you can keep using the volumes and use the remesher tool to get nice topology
