    Layout and Thermal Analysis of Power Devices Using a PC/XC by J. N. Avaritsiotis, G. Eleftheriades

    Published 1990-01-01
    “…Traditionally, a solution of the thermal problem is obtained by either the method of finite differences or the method of finite elements. Both methods, however, require a fine 3-D partition of the substrate, leading to large systems of linear equations the solution of which demands substantial computing power provided by number crunching machines and/or powerful computer work-stations.…”
