This repository contains the educational material and source codes used in the laboratory session "Method of Characteristics for Advection" of the course Models and Simulation of Flows and Facilities, taught within the Master's in Industrial Engineering at the **University of Zaragoza (UNIZAR). For additional information about the course, please visit: https://estudios.unizar.es/estudio/asignatura?anyo_academico=2025&asignatura_id=60828&estudio_id=20250681¢ro_id=110&plan_id_nk=532 The objective of this practice is to introduce students to the numerical solution of the one-dimensional linear advection equation using the Method of Characteristics (MoC). The implementation follows the methodology described in the practice guidelines and allows students to understand the concepts of characteristic tracking, interpolation, and numerical transport of scalar quantities.
