A numerical algorithm is described for computing coupled heat and hydrodynamic flow on an arbitrarily shaped, time-varying domain. The algorithm extends the ICED-ALE method, for the computation of hydrodynamic motion using an arbitrary Eulerian-Lagrangian mesh, to include electron thermal conduction. Appropriate difference equations in conservation form are developed, and the Dufort-Frankel scheme is adapted to advance these equations in time. Results are presented which illustrate the application of the algorithm to the two-dimensional hydrodynamic motion induced by illuminating spherical and thin foil targets with a single laser beam.
