Misassigning element issue (Abaqus 6.14 and 6.11-2)

Misassigning element issue (Abaqus 6.14 and 6.11-2)

Misassigning element issue (Abaqus 6.14 and 6.11-2)

(OP)
Hello! This is my first post on this forum so if it doesn't belong here please let me know.

I've been working on a finite element phase field analysis of shape memory alloys. The goal is to cool the material using a step quench in the first time step and then hold it for an addition two time steps. My material parameters come from a VUMAT, the general geometry is a 2D "slice" of the material which should transform from one structure to another with temperature. Boundary conditions are a pinned node in the center of the square and a rolling condition on the lower left node.

The issue I've been having is a set of elements that exist as the opposite structure they are assigned as and do not transform (surrounding elements are fine), appearing as a square in the middle of the material. The output should show a red square with a blue oval without 'sprinkles' as seen in the attached images. This only occurs if I use Abaqus 6.14, the issue does not appear if I use Abaqus 6.11. I'm wondering if anyone else has seen a discrepancy between different versions of Abaqus that could explain this? There is no issue running it on the previous version, it is more computationally expensive to run the older version on the supercomputer. I'm mostly just curious why this would occur.

Any insight would be great! Thank you!
