Import analysis issues - stresses dropping rapidly

[ryankb]

Hello all, I'm hoping someone can shed some light into an issue I've been having this week. I'm running Abaqus explicit, a nitinol product is hitting a wall. Nitinol is modeled as beam elements, wall is solid elements. I think something with the restart isn't quite working properly, because in the very first increment in my import analysis, the stress drops dramatically in the nitinol. Also, when looking at the internal energy, it too drops dramatically - despite the last increment of the original job and the first increment of the import analysis are at basically the exact same position.

Has anyone else encountered this before? I am fairly certain that if I were to run this as one giant job I'd be fine, but I'm trying to work on the last little part, and I don't want to wait for over 30 hours of run time before I can see if my last attempt worked.

Thanks!
