Injection molding simulation research requires a considerably advanced computer code, which is particularly true when including crystallization modeling. The code and simulation setup are made openly available to further the research on the topic. Insight into the thermomechanical conditions is provided with through-thickness plots of pressure, temperature and cooling rate at different levels of crystallinity. The prediction of the cavity pressure evolution is used for the assessment of the solution quality because it is experimentally available and governs the residual stress development. Deviatoric elastic stress is evolved in the solidified material. Latent heat is released according to the crystallization progress and temperature. Specific heat depends on temperature and crystallinity. The thermal conductivity is pressure- and crystallinity-dependent. The heat transfer coefficient in the thermal contact towards the mold depends on contact pressure. A number of physical interdependencies are included. The crystallization behavior of high-density polyethylene (HDPE) is implemented according to theoretical and experimental literature. This work investigates crystallization modeling by modifying an open-source computational fluid dynamics code OpenFOAM.
