What is HETVAL subroutine in Abaqus? | Learn all about HETVAL in curing process simulation

This video tells you what is the HETVAL subroutine? When we need it; and how does it work in a practical example: Composite curing process. Also, learn about the HETVAL subroutine variables so you can write your own subroutine.
HETVAL is a subroutine designed to overcome the limitations of Abaqus in effectively managing volumetric heat flux caused by internal heat generation within materials. This subroutine's capabilities are based on various factors like time, temperature, or evolving state variables, which are stored as solution-dependent variables. As a result, it can handle complex scenarios involving phase changes during simulations. Additionally, the subroutine enables the incorporation of kinetic theory to accurately represent phase transformations related to internal heat release, such as predicting crystallization in polymer casting processes. This versatile subroutine finds applications in various analyses, including heat transfer, coupled thermal-electric studies, and temperature-displacement analyses.
