안녕하세요. 6월 사용자교육에 참석했던 현종우입니다.
제가 수중글라이더 강제운동에 관심이 있어서 홈페이지에 있는 예제파일을 돌려보았습니다.
처음 RA 예제를 할 때 버전이 안맞아서 약간의 수정이 필요하다는 조언을 들었습니다.
RA의 경우에는 문제 없이 계산이 완료되었고 결과도 pdf에 제시된 것과 같게 나왔습니다.
PMM 예제도 수정이 필요했었습니다. 아래는 수정한 내용입니다.
변경내용===================================================================
1. 0/epsilon,k,p,U,phi,nut : torpedo(or new_torpedo) -> new_new_torpedo
2. fvScheme : dev -> dev2
3. controlDict : rhoname -> rho
4. turbulence Properties : RASModel -> RAS, 하단에 RAS 정보 입력
5. decomposeParDict : simple -> scotch
===========================================================================
위와 같이 바꾸고 decomposePar 후 'pyFoamPlotRunner.py mpirun -np 4 pimpleDyMFoam -parallel'로 실행을 하였는데
1초까지 계산을 수행한 후 에러 메세지가 나왔습니다. 내용은 아래와 같습니다.

병렬계산에 문제가 있나싶어 그냥 pimpleDyMFoam으로 돌려보았는데도 동일한 에러가 나왔습니다.

위에 제시된 경로에는 data라는 파일이 없었습니다. 어떻게 문제를 파악하고 해결해야 할지 몰라서 여쭤보려고 합니다.
다른 곳에서 더 바꿔야 하는게 있는지요....
