Hi everyone;<\/p>\n

I was simulating a liner located on a hopper. (view image).
The idea is that the liner is supported on the hopper structure, so there would be a non-linear frictional contact between these elements.
NOTE: The liner is not welded to the structure, it is a removable element, simply resting on the hopper.<\/p>\n

There are 2 pins, which contribute to the liner not falling off, however they are loose pins. Therefore these contacts would also be friction.<\/p>\n

In addition, the pins will be welded to the hopper structure.
The problem that happens is that the non-linear contact that I put between the pins and the liner is ignored, even though I have modified the pinball region.<\/p>\n

How could I solve this problem<\/p>\n

Note: The attached image shows a coarse mesh, however I have refined the mesh and the same problem still occurs. Also for simplification I am placing a contact without friction.<\/p>\n

Thanking you for your support<\/p>\n

Greetings<\/p>\n
