The finite element Heat Transfer and Erosion Analysis Program (Hero) provides solutions for multidimensional ablation, internal heat conduction, thermal decomposition, and pyrolysis gas flow problems. As part of a code validation study, two-dimensional axisymmetric results from Hero are compared with thermal response data obtained from arcjet tests. The results are also compared with two other two-dimensional axisymmetric computational methods (Fully Implicit Ablation and Thermal (FIAT) and Finite Element Ablation and thermal Response (FEAR)). Hero model predictions compare favorably with the arcjet test data for all conditions and other computational methods where there is not significant pyrolysis. Where pyrolysis occurs, the Hero model more accurately predicts surface recession than the FIAT and FEAR codes. This serves to validate the methodology used in the Hero code.
