Description

Recently, some practical numerical analyses using simple programming process of Excel have been reported. In the analysis, each cell of the spreadsheet can be regarded as a nodal point, and calculations are performed by using equations written in those cells. Accordingly, a concrete image corresponding to the physical model can be drawn on the spreadsheet, and by doing classification based on colouring boundary and interior cells, writing and debugging are visually conducted with ease. In the present study, as an application of the useful method to thermal analysis on electronic equipment, visualization of programming and calculation processes by thermal network method have been shown by using the concrete example of a housing heated by solar radiation.
