I am running a sequentially coupled thermal/stress analysis in ABAQUS (i.e. 2 different models) for a semi-crystalline polymer where the crystallinity is defined in the heat transfer model as a user-defined state variable and I want to use the results in the stress model. However, I can't figure out how to import the result as a predefined field like I do the temperature. It seems like maybe I can use UFIELD but I can't seem to find any examples of how I would do it. Anyone have a simple example of how to import user-defined state variables into an analysis as a predefined field?
