The paper proposes a new concept to use the diffusion equation for heat flow estimation in a composting process. Only general ideas are described, without the full mathematical model and without experiments. The lack of the detailed description stems from the fact that such an approach was not (as it seems) used earlier, and the details are to be developed. The article describes the preparatory work in this field. In the first part of the article, derivation of the diffusion equation is presented together with using an approach consistent with modern Computational Fluid Dynamics, in which all fluid phenomena in a Control Volume are considered. In the second part of this article, the basic information about implementation and needed programming techniques are described. It is emphasized that the diffusion equation is adequate not only for the temperature flows, but for other phenomena as well. The main purpose of this study is to create a general template for 3D modeling of phenomena which are diffusive in nature.
