- Participation in Essential CFD is recommended (skills are carried over into this course)
Competence in CFD with OpenFOAM
- This course has been designed over 6 months, drawing on 2000 hours OpenFOAM training experience.
- It enables competency: the confidence to repeatedly carry out CFD analysis to a defined standard.
- Confidence = not freezing at the keyboard.
- Repeatedly = delivering a good solution, and another…
- Defined standard = understand what a good solution is and delivering solutions in a timely manner.
- It addresses the challenges of CFD analysis through a modular curriculum.
Learning CFD through Experience
- The training involves learning through experience.
- We use representative cases spanning a range of scientific disciplines and industries.
- E.g. external aerodynamics of a car, propeller, wind flow around buildings, static mixer, nozzle jet, cyclone, water channel.
- CFD solutions are built in small, digestible steps with periods of reflection to reinforce new concepts.
- This reflects real CFD practice, where trouble-free, complex simulations cannot usually be set up in “one go”.
