저는 STAR-CCM+®를 사용하기 전까지 내 경력의 대부분을 오픈소스 CFD 툴을 사용하는데 소비했고 무료 시뮬레이션 소프트웨어에는 종종 비싼 가격이 동반된다는 것을 마침내 깨달았습니다. 이 말이 모순처럼 들릴 수 있지만, 한 푼 지출 없이 마우스 클릭 한 번으로 다운로드하여 자유롭게 사용하고, 수정, 그리고 공유하는 것은 보이는 것보다 싸지 않습니다. 작업에 소요된 시간에 있어 시뮬레이션 소프트웨어의 진정한 가치를 고려해보면 거기에는 광범위하게 숨겨진 비용이 있음을 알아야 합니다. 시간의 가치는 얼마일까요?

I am not a soccer fan, but all the men in my life are fanatics and thus World Cup fever has taken over the Goodwin household. You might be surprised at what happens when an uninterested CFD engineer is forced to watch soccer...

I wanted to take a moment and shine the spotlight on our coupled density-based solver. I must admit, I am perhaps a bit of a biased writer because after all, I have spent most of my career in industry analyzing and optimizing aircraft performance in flight regimes where the need for accurate shock capturing was part of daily life. Coupled solvers with a density-based approach have a proven track record for delivering robust solutions for these types of applications so it should come as no surprise that these numerical methods continue to spark my interest.

The biggest challenge of gradient-based shape optimization using high-fidelity CFD has always been the formidable computational expense tied to constructing the sensitivity of the objective (or cost) functions with respect to the design variables.
