Two server computers are available for the modeling and industrial scale manufacturing systems processing 120 X 60 cm. modules have been simulated. The agreement between modeling and experimental data is very good. For example, in heat transfer modeling with radiation boundary conditions, the temperature results are within 2% of measured values. In the simulation of industrial scale systems, all the details of the hardware are incorporated (i.e., the geometry is not simplified for modeling) and the material properties as a function of temperature are input into the program.<\/span><\/p><p class=\"zw-paragraph\" style=\"color: #000000;\"><span class=\"zw-portion EOP\">\u00a0<\/span><\/p><p class=\"zw-paragraph\" style=\"color: #000000;\"><span class=\"zw-portion EOP\">\u00a0<\/span><\/p><address class=\"zw-paragraph\" style=\"color: #000000;\"><span class=\"zw-portion\" style=\"color: #000000;\">1.\u00a0<\/span><span class=\"zw-portion\" style=\"color: #000000;\">Kephart<\/span><span class=\"zw-portion\" style=\"color: #000000;\">, J.
