Hello,

I am trying to look at an analysis on a progressive spring for a project. I am a bit of a novice with Abaqus. I got a spring from grab cad and ran through the whole project. I placed a plate on top and bottom of the spring so that I can apply a load. If I have the contraints tied I get an error that the volume of several elements are small, negative, or zero. So I applied a friction factor of 0.5 at the surfaces. Now, the only way I can get a job analysis is if I set a displacement of -5 on the upper plate. If I increase the displacement to something like -20 or even higher, I get an infinite amount of attempts for the first increment. The same error happens when I leave the boundary condition for the top plate as free in thee Y direction and apply a load of any magnitude. Please let me know how I can fix this. I need to be able to apply a load or a bigger displacement for my project.
TIA
