Abstract
A review of the classic techniques used to solve ablative thermal response problems is
presented. The advantages and disadvantages of both the finite element and finite difference
methods are described. As a first step in developing a three dimensional finite element based
ablative thermal response capability, a one dimensional computer tool has been developed.
The finite element method is used to discretize the governing differential equations and
Galerkin's method of weighted residuals is used to derive the element equations. A code to
code comparison between the current 1-D finite element tool and the 1-D Fully Implicit
Ablation and Thermal response program (FIAT), a NASA-standard finite difference tool,
has been performed.
