I’m trying to run a simulation of a crude soft robotic actuator, essentially a silicon rubber tube constrained radially in a PLA filament wrapping. It ran yesterday but failed, running out of time. I tried to rerun it today and it doesn’t even start saying ‘An error occurred’ but there’s no solver log to look at.
Thinking my timeout problem yesterday was due to complexity I tried simulating a smaller simplified model without the wrapping. This also won’t start in the BETA workbench. Creating an identical simulation in the old workbench starts but fails with a matrix factorisation error, though I cannot see why as it has a limited constraint at one end of the tube which is otherwise free to expand as it would like.
What am I doing wrong?
