openFOAM tutorial

한참 시도하다가 실패했던 openFOAM 사용예를 찾아보려는데

chatGPT 시대니까 한번 시도!

실행 예제: OpenFOAM을 실행해보기 위해 예제 중 하나를 실행해보겠습니다. tutorials 디렉토리에는 다양한 예제가 포함되어 있습니다. 예를 들어, heatTransfer/buoyantSimpleFoam 디렉토리로 이동한 후 다음 명령을 실행하여 해당 예제를 실행합니다. shell Copy code $ cd $FOAM_TUTORIALS/heatTransfer/buoyantSimpleFoam $ blockMesh  # 메쉬 생성 $ buoyantSimpleFoam  # 시뮬레이션 실행 이 예제는 열전달과 대류 역학을 시뮬레이션하는 것으로, blockMesh로 메쉬를 생성한 후 buoyantSimpleFoam으로 시뮬레이션을 실행합니다. 실행 결과는 해당 디렉토리 내에 저장됩니다.

 

일단은 heatTransfer / buoyantSimpleFoam 

라는 키워드를 얻었으니 이걸 기반으로 역으로 추적해보면..

 

머.. 검은 건 글씨고 흰건 종이라는 건 변함없다.. -_ㅠ

bard에게 물어보니

OpenFOAM 워크벤츠 프로그램을 엽니다 라고 해서 찾아보니..

뜬금없이(?) freecad에 plugin이 튀어나온다.. bard가 나에게 맞말을 해주는게 아닌 느낌?

파일 경로는 찾았는데 실행 방법을 모르겠다 ㅠㅠ

paraView 혹은 paraFoam이 먼진 모르겠는데.. 이거 맞나?
