Abstract: Abstract Precipitation processes are modeled by population balance systems. An expensive part of their simulation is the solution of the equation for the particle size distribution (PSD) since this equation is defined in a higher-dimensional domain than the other equations in the system. This paper studies different approaches for the solution of this equation: two finite difference upwind schemes and a linear finite element flux-corrected transport method. It is shown that the different schemes lead to qualitatively different solutions for an output of interest.
