Abstract
A new visual-oriented numerical method which applies the spreadsheet of Excel has been proposed. In the present study, a programming process on two-dimensional steady-state heat conduction problem in the rectangular coordinate system is explained by way of a specific example, where a volumetrically heat generating rectangular region with a concave is heated uniformly at one wall and other walls are kept at some temperatures. The present steady-state numerical calculation has been realized by introducing icon cells in which difference equations concerning the inner, boundary and singular points etc. are embedded. Through the programming process using this specific model, the proposed method is shown one of the useful numerical methods.
