1. CFD-DEM설치 이전에 필요한 설치환경이다.
- Ubuntu
- FFMPEG
sudo apt-get install ffmpeg- LIGGGHTS
- OpenFOAM
2. 환경설정
CFD-DEM의 환경설정에 앞서, ./bashrc를 통해 컴파일 환경을 설정하여야 한다.

이중 흔히 제기되는 문제가 bash에서 cfdemSysTest 명령어가 안먹는다는 애로사항이 Forum에 꽃 피고 있다. 아래와 같이.
$ cfdemSysTest
cfdemSysTest: command not found원인은 bashrc가 제대로 세팅이 안되서 그렇다.
위의 링크에서는 아래의 스크립트를 $HOME/.bashrc에 추가하라고 한다.
#================================================#
#- source cfdem env vars
export CFDEM_VERSION=PUBLIC
export CFDEM_PROJECT_DIR=$HOME/CFDEM/CFDEMcoupling-$CFDEM_VERSION-$WM_PROJECT_VERSION
export CFDEM_PROJECT_USER_DIR=$HOME/CFDEM/$LOGNAME-$CFDEM_VERSION-$WM_PROJECT_VERSION
export CFDEM_bashrc=$CFDEM_PROJECT_DIR/src/lagrangian/cfdemParticle/etc/bashrc
export CFDEM_LIGGGHTS_SRC_DIR=$HOME/LIGGGHTS/LIGGGHTS-PUBLIC/src
export CFDEM_LIGGGHTS_MAKEFILE_NAME=auto
export CFDEM_LPP_DIR=$HOME/LIGGGHTS/lpp/src
. $CFDEM_bashrc
#================================================#
그런데, 영어 설명이 모호하다.
You need to set some environment variables in ~/.bashrc (if you use c-shell, manipulate ~/.cshrc accordingly). Open your .bashrc and the CFDEM®coupling bashrc file.
gedit ~/.bashrc $HOME/CFDEM/CFDEMcoupling-PUBLIC-$WM_PROJECT_VERSION/src/lagrangian/cfdemParticle/etc/bashrcAdd the STANDARD block to the end of your bashrc and modify entries if necessary. Make sure the statements are not comments; remove the “#”. Similar to:
문제의 원인은 간단하다. bashrc 파일은 $HOME에도 있고 $HOME/CFDEM/CFDEMcoupling-PUBLIC-$WM_PROJECT_VERSION/src/lagrangian/cfdemParticle/etc/bashrc 여기에도 있다.
위의 추가되는 스크립트는 $HOME/CFDEM/CFDEMcoupling-PUBLIC-$WM_PROJECT_VERSION/src/lagrangian/cfdemParticle/etc/bashrc 를 열어보면 주석 "#"로 막혀있다. 여기의 주석을 열라는 것이 아니라 여기의 스크립트를 복사해서 $HOME 밑에 있는 bashrc에 붙여 넣으며 주석"#"을 지우라는 이야기다. 그러면, 마지막 스크립트
. $CFDEM_bashrc이거슨 $HOME/CFDEM/CFDEMcoupling-PUBLIC-$WM_PROJECT_VERSION/src/lagrangian/cfdemParticle/etc/bashrc 이걸 찍어서 실행시키는 것이다.
최종적으로 아래와 같이 $HOME/.bashrc 를 다시 실행시키면 경로를 쭈욱 재설정한 후 $HOME/CFDEM/CFDEMcoupling-PUBLIC-$WM_PROJECT_VERSION/src/lagrangian/cfdemParticle/etc/bashrc 이걸 찍어서 실행 시켜서 컴파일 환경을 세팅하겠다는 거다.
source ~/.bashrc성공하면 아래와 같은 결과를 얻을 것이다.
$ source ~/.bashrc

아래 문제는 ./bashrc에서 PATH를 정확히 바꾸어 주면 된다.
!!! WARNING CFDEM_LAMMPS_LIB_DIR = /home/hp-z8/LIGGGHTS/LIGGGHTS-PUBLIC/src/../lib seems to be wrong !!!
그러면 위의 PATH문제는 사라지는데, valid NO 인 것들을 살펴보면, LPP, C3P0이다. 참고로 포럼에는 PIZZA까지 포함해서 없어도 컴파일에는 무방하다고 한다.

trying to start paraview...
Allrun.sh: line 81: /home/hp-z8/software/ParaView-4.3.1-Linux-64bit/bin/paraview: No such file or directory무언가 된거 같은데, Paraview 버전이랑 PATH도 다르고, 어디에 해석결과가 세이브 되는지는 좀 더 찾아봐야 겠다. 힘든 여정이다.
