Computational fluid dynamics is getting more and more an established reality in nowadays engineering applications involving fluids. Being able to simulate fluids’ behavior in different cases and configurations is an incredibly strong tool that has a big impact on different engineering fields varying from components design to climatic effects. A lot of research is currently based on using CFD software to obtain results in a faster, easier and less expensive way, compared to reproducing the fluids’ behavior in experiments. That is why it becomes very interesting understanding what tools are available in the literature, what’s their current status, how to better adopt them.
