여기는 연산하는 거고

이제 보는건  paraview를 쓰면 된다.

1. 좌측 상단의 폴더 눌러서 파일 열기

 

2. elbow_tri/system 디렉토리에서 파일을 모든 유형으로 선택하고 controlDict를 연다.

 

3. OpenFoam 유형으로 연다.

 

4. apply를 누른다.

(처음 열어 보면 그냥 wireframe만 나오는데, icoFoam 까지 하고 나서 다시 열면 색상이 보인다)

 

5. 상단에 U로 바꾸어 주고 재생 버튼을 누르면 75초간 시뮬레이션 한 결과가 재생된다.

 

오.. 신기해라(영혼 없음)
