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 unsteady-state heat conduction problem in the cylindrical coordinate system is explained by way of a specific example, where a short round bar is put under sudden heating on its end and is cooled by forced convection around its side surface. The present unsteady-state numerical calculation has been realized by introducing icon cells in which difference equations concerning the inner and boundary points are embedded. Through the programming process using this specific model, the proposed method is shown to be one of the useful numerical methods.
