Description

Hero (Heat Transfer and Erosion Analysis Program) is a multi-dimensional thermal ablation code developed by ATK. The program is based on a hierarchic finite-element numerical scheme with a variable grid. Calculations for heat transfer, material pyrolysis, internal pore pressure and thermochemical surface ablation are provided. The program is well-suited for modeling of complex geometries and anisotropic materials. The program also includes capabilities for surface-to-surface radiation exchange as well as structural modeling using the same grid used for thermal solutions. The structural capabilities enhance modeling of thermal-structural interactions and facilitate research related to the thermal-structural response of ablative insulators. The program has been extensively verified for numerical accuracy. Recent enhancements to the program have included error estimation, adaptive discretization and element enrichment, and parallel processing capabilities.
