At present,most of the heat transfer simulation models are solved numerically with the help of commercial software,which is not conducive to understanding the influence of different boundary conditions on heat conductivity.Visual Basic(VB)language is used to establish a numerical model solver for two-dimensional steady-state heat conductivity,which intuitively displays the temperature distribution in the heat transfer process,and obtains the sensitivity of heat conductivity to different boundary changes by analyzing the influence of fixed boundary heat flux density and fixed boundary temperature change on heat conductivity.
