Abstract:

This document presents a users manual for the Aerotherm Axi- Symmetric Transient Heating and Material Ablation Program, Version 3 ASTHMA3, including a general description of program capabilities and solution procedures as well as a detailed set of input instructions. ASTHMA3 is a transient heat conduction program for two- dimensional, axi-symmetric bodies. Multiple non- charring, anisotropic materials may be studied. The surface boundary condition has three options, including an unusually general thermochemical erosion or ablation condition as well as simplified radiation and specified temperature options.
