I’m trying to run a contact simulation between a “stiff” eraser and a “soft” block. In Abaqus the simulation should look something like this:
Frictionless w/ Implicit Dynamics (Backward Euler)
Friction w/ Implicit Statics
I understand that friction isn’t supported yet in the end-user Flex/Crunch stack, so I’m working on the former, frictionless problem. I seem to be having all sorts of issues with losing contact as the eraser passes over element interfaces on the block. I’ve used
Uniform30 for master seeds and slave quadrature in the video below. I’ve tried swapping master and slave surfaces, soft-contact, varying penalty, only
gpts_2D works (the other formulations crash at instantiation), tighter tolerances… I’m just a bit lost. I was wondering if someone could help me understand what’s going wrong and how to fix / alleviate the problem.
And here’s just a simulation input deck – I think it’s the one that made the video above.
