Good morning! 

I posted a little while ago about some work I'm doing modeling the behavior of fiber optic cables during temperature cycling. The good people here were extremely helpful back then and I'd like to pick your brain again! 

Since my last post, I've had a lot of success adding complexity back into my model. The most recent iteration has 12 fibers each with three layers or bonded material, the optical fiber, and two layers of acrylate with different material properties. On the edges, there are aramid fillers and then it is all surrounded by a plastic jacket material. 

Unfortunately on my current computer, the simulation takes about 48 hours to run which is why I'd love to see if anyone might know quickly what's going on here to save me some weeks of trial and error. My simulation converged, but for some reason one of the fibers has much higher stress than any of the others. This seems odd and I don't think it should be the case. The local interactions have the same parameters as the other fibers and the material is correctly selected. Even the contact pressure seems to be way higher on this one fiber for some reason. 

I did have to reduce my mesh complexity a bit due to ram constraints (hoping to get a more capable computer soon). Would that have anything to do with it? The acrylate layers overlap a bit, but they do this in all the fibers. 

I'm limited in how many screenshots I can add but can post more info as needed. If you think you know what's causing this let me know!
