Array nYou are showing compression as a positive value.nIf compression is along the X axis, that means the right end of the spring is fixed, while the left end of the spring moves to the right along the positive X axis.nPlease mark the blue curves with arrows or a legend to show compression and release. For example, use an arrow pointing to the right on the branch of the blue curve that was traced when the left end of the spring was moving to the right and the spring was being compressed. Use an arrow pointing to the left on the branch of the blue curve that was traced when the left end of the spring was moving to the left and the spring was being released.nDoes your material include plasticity? I expect you will need that to get a large nonlinear behavior.nYou say The graph is different when all helix are in contact with each other. Please show that graph.nPlease reply with images of the geometry and the mesh.n
