Aerodynamical engineers commonly use Fluent for modeling airflow, which utilizes Finite Volume techniques rather than Finite Element methods. In addition to Fluent, many engineers develop their own codes, often in Fortran, which can enhance their professional prestige. The discussion emphasizes the importance of both established software and custom solutions in the field of aerodynamics. Overall, Fluent remains a key tool for fluid flow modeling among professionals. Custom coding is also valued for its ability to meet specific project needs.
