Hi, is anyone ever run a non-linear creep analysis in temperature cycling condition?
I am simualting the creep strain of a plastic component in 0 - 100deg C temperature cycle (5 minutes dwell at the mentioned temperature and 5 minutes for temperature ramp up/ramp down). It always gives an error message of "calculated creep time less than minimum allowed value. Modify time stepping criteria or reduce minimum time step allowed". I have try to reduce and play with the time stepping criteria (until 0.001s), but it doesn't help, and I don't think further reducing the time step will help. Somemore, I need to run the simualation for 5000+s, it's not realistic to run with a very small time step. Can any one help on this?
Thanks.
