Control additional parameters to tailor your analyses.
There are several analysis parameters you can provide in addition to those specified by the user-material constants as described in Appendix A. The HIN file is an auxiliary text file created manually, that contains these parameters and their associated keywords. The use of the HIN file and current functionality is described below.
Material definitions and properties that reside within the HIN file always supersede any definitions or properties within the Abaqus user material definition or the material file (mdata). For example, if instantaneous degradation damage evolution is defined within the user material, but the HIN file defines energy based degradation, (Damage Evolution) the energy based degradation definition will take precedence over the instantaneous degradation definition. This rule is consistent with a migration towards the HIN file and away from user material constants. In future versions of Helius PFA user material constants will be deprecated for most functionality and the HIN file will be required.
