FAQ

Frequently Asked Questions

CFD is the universal acronym for Computational Fluid Dynamics.

No, it applies to all fluids, including liquids like water and oil, and gases like air and steam.

While writing custom CFD code requires programming, many engineers use commercial CFD software with graphical interfaces, focusing on setup and interpretation.

Computational Fluid Dynamics (CFD) specialises in fluid flow. The Finite Element Method (FEM) is a numerical technique used in CFD but also in structural analysis and other fields.

A branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyse problems involving fluid flows.

Computational fluid dynamics is usually technical/academic in register.

Computational fluid dynamics: in British English it is pronounced /ˌkɒmpjʊˈteɪʃənəl ˈfluːɪd daɪˈnæmɪks/, and in American English it is pronounced /ˌkɑːmpjʊˈteɪʃənəl ˈfluːɪd daɪˈnæmɪks/. Tap the audio buttons above to hear it.
