A newly developed visual-oriented numerical method for solving the two-dimensional unsteady-state heat conduction problem which applies the spreadsheet of Excel is explained through a simple physical model. The present unsteady-state numerical calculation has been realized by introducing a dummy sheet with empty cells and a sheet with icon cells, in which difference equations concerning the inner, boundary and singular points and so on are embedded. By organizing and expanding such sorts of icon cells, the proposed method is expected to get applied against much wider range of heat transfer problems in the future.
