Hello everyone.
I have assembled a model of rubber deformation. The ring should press the rubber.
I use units ms, mm, GPa.
But during the calculation the ring does not see the rubber, passes through it and the calculation is completed in a minute.
I used different types of contacts but nothing helped.

I also tried to change the eleform in the SECTION section.
I changed the calculation time and steps and many other things, but nothing helps.
I used AUTOMATIC_SURFACE_TO_SURFACE, I also tried to use one card for all AUTOMATIC_SINGLE_SURFACE.
How can I make the contact visible? Please help.
I am attaching the contact settings:

when you have your input file ready for solving, load into LSPP and do a contact check there under application--> model checking --> General Checking.   

you also have a single surface 0 0 5, probably want to get rid of that.   If you use workbench to prepare model, turn off body interaction thing, that's turned on by default but should always be turned off.

Yes sir where there was 0 0 5 it was a test version from VB.

I did a contact check, this is what came out of it:
