Abstract The discrete-sectional method to solve the general dynamic equations is a useful tool for the simulation of an evolving aerosol population. This tutorial is intended to equip the reader with the necessary knowledge to implement this method for a single component system. To this end, we provide step-by-step instructions on the construction of a discrete-sectional model, including details on simulation bin configurations and all the necessary equations to describe relevant physical processes in an aerosol, i.e. condensation/evaporation, coagulation, and external particle losses. Supplementary to the text is a functional, open source MATLAB code that implements the framework introduced in this tutorial. The interested readers can use the code either for learning purposes or to meet research demands. Lastly, we designed six test cases not only to verify the validity of our discrete-sectional model, but also to help the reader gain insight into the evolution of aerosol systems.
