HETVAL subroutine in ABAQUS

HETVAL subroutine is used to define heat flux due to internal heat generation in a material. This subroutine could be dependent on state variables(such as the fraction of material transformed).HETVAL subroutine can be useful if it is necessary to include a kinetic theory for a phase change associated with latent heat release (for example, in the prediction of crystallization in a polymer casting process).HETVAL subroutine can be used in conjunction with USDFLD subroutine if it is desired to redefine any field variables before they are passed in, and it cannot be used with UMATHT subroutine.

In the “HETVAL subroutine in ABAQUS” package, you will learn how to write this subroutine by implementation it on different simple and complex problems step by step.
