SALTY: A hybrid computer program for three-dimensional heat transfer from a discrete source

SALTY, a hybrid computer code, was written for calculation of the temperature distributions in an extended medium with spatially varying properties and one or more discrete energy sources. Such complex, multidimensional, time-dependent simulations constitute one useful application of the parallel computation and continuous integration capabilities of the analog-digital hybrid computer. An application of SALTY to a problem involving nuclear waste disposal in salt is described, and the results are compared to those from the pure digital code HEATING5. SALTY gives much the same results at a lower computer cost. Differences in the results are discussed.
