Hi Peter,
I do not see any attached archive file.
I have a similar 2D axisymmetric model where I have a contact spring setup and wanted to understand the dynamics of a part under force. I also wanted to do a parametric study with different stiffness values and their effect on the dynamics of the part. But when I plotted the deformation of the part under various stiffnesses ranging from 200 N/mm to 500 N/mm, all the deformations were exactly the same.
I did a similar sensitive study with ranging preloads which worked but changing stiffnesses did not work. Does anyone know the reasoning and solution?
P.S. I tried setting up the Spring contacts in the respective coordinate system of contacts rather than Global. Did not work either.
keenly awaiting your suggestions
