Hi, Did you visualize your simulation? I doubt if this script can produce the correct physics. Last time, I stated that I believed one Chrono body was enough, and you had to collect force from both pieces of your meshes. This script uses at least 4 ChBodies (it may work, but I do not understand how they are used here) and seems the force is collected from the tip mesh only. Again, that's my speculation, because I don't know the mesh you used; but I doubt it would work, with low *or* high Young's modulus. It may happen to not throw an error at certain settings.
Perhaps more importantly, I know the tip force is what you are after but did you manage to get a one-mesh-one-cone test scenario running, visualize it and validate the physics it produces? I think you have to start there, and if you have that the rest should follow naturally.
