I'm revisiting my analysis from my discussion "Large Deformation FEA". Though I received a lot of useful info, I'm still struggling to get accurate results.
Attached is the file I'm analyzing as a contact analysis assembly.
This screenshot captures most of the details (mapped mesh constraints, contact surfaces, total load at point, symmetry, displacement):
It also shows that this test failed with my given material properties. It will run with other material properties, but I haven't gotten anything close to real results.
Also, when I run this analysis, I get odd results and it's still taking my computer a while to solve this with mapped mesh and only one part with nonlinear material properties:
I assume it's because my contact point at the top is sharp that it sees a little interference and then overcompensates.
Have you all seen issues like this?
Any suggestions would be greatly appreciated.
Thanks!
