====OpenFOAM====

  * [[https://www.openfoam.com/|OpenFOAM]]

===Installing OpenFoam===
  * Installing OpenFoam requires the use of the Sudo command therefore system admin needs to perform the first 4 steps from [[https://openfoam.org/download/11-linux/]]. User needs to be added to Docker group also.

  * Ran OpenFOAM Docker image on Littlestorm. Following this procedure:

1) Edit your ~/.bashrc file and add the line: export XAUTHORITY=$HOME/.Xauthority

2) Start with "Step 5: Launching openfoam11-linux" at the following link [[https://openfoam.org/download/11-linux/]]  However, when you get to the last line that launches "openfoam11-linux" ,  you instead need to launch it like this: openfoam11-linux -p 510 -xhost  <--This will ensure that graphical programs get passed through and show up correctly when xforwarding.   You may not need the extra flags if you are using a VNC session.
  *Step 5 from link:

   mkdir -p $HOME/OpenFOAM/${USER}-11
   cd $HOME/OpenFOAM/${USER}-11
   openfoam11-linux -p 510 -xhost

3) Once in the container, return to [[https://openfoam.org/download/11-linux/]], and go to Step 6: Testing openfoam11-linux. This should ensure that everything is set correctly and afterward you should be ready to work with the program.
  *Step 6 from link:
    *Testing OpenFOAM

    mkdir -p $FOAM_RUN
    cd $FOAM_RUN
    cp -r $FOAM_TUTORIALS/incompressibleFluid/pitzDailySteady .
    cd pitzDailySteady
    blockMesh
    foamRun
    paraFoam

===Older Versions===
  *The [[https://develop.openfoam.com/Development/openfoam/-/wikis/precompiled/docker#running-openfoam-in-a- 
   container]] contains the latest version of the OpenFOAM docker image, it updates automatically on their website.
  *To install an older version go to [[https://openfoam.org/]] and type "Download v#" (# = preferred version). 
   Note: every different version will need to be installed by a system admin.
