：A heat conduction analysis is often required for the deep geological disposal of nuclear waste, while the traditional heat conduction analysis, which is based on a continuous model, fails to describe the details of heat transfer between two contacts. In view of this problem, firstly, based on the particle simulation method, the material is discretized into a series of heat storage and heat pipes, thus realizing the temperature exchange through the network composed of heat storage related to particles and heat pipes related to contact. Then, the program architecture is built through Qt, thus achieving the visualization by using the open graphics program interface OpenGL, followed by a verification of its correctness based on an analysis of the heat conduction characteristics of one-dimensional thin plate and two-dimensional symmetrical ring. Meanwhile, a research is to be carried out on the effects of particlesize and stacking mode on heat transfer. The results show that this method exhibits an improved performance in the simulation of the heat transfer process of materials.
