I hope this finds you well.
I am attempting to simulate the compression of a silicone test subject. The silicone subject is cylindrical in shape, 50mm tall with a fillet of 15mm and a radius of 45mm.
The model can be seen below:
I am using pure penalty contact, nodal-normal from target.
I am solving a 30mm lubricated compression in 40 steps.
Here are the settings I am using:
I have attempted to use other hyperelastic materials to simulate such as Mooney-rivlin 3 parameters and Yeoh 1st order, however the simulation fails at 12 steps.
There is no specific error that I am receiving. Instead in the solution output I am getting a message saying the solution failed to converge.
I have attempted to use higher order elements but that makes the solution fail earlier. I've attempted to refine the mesh of both the plates and the silicone subject respectively with no change in the output.
I have attached the archive of the project.
