The class will be both theoretical and applied. The goal is to introduce the use of OpenFOAM for numerical simulation execution.

The attendance is strongly recommended

The project consists of a scientific report describing the numerical simulation performed in agreement with the teacher and the comparison of the results with the data available in the literature
