2 Introduction and Notes

Anyone reading this is welcome to updating this section. You can take inspiration on the other existing pages that are referenced on the parent page: Installation/Mac OS

Here are notes on installing OpenFOAM 2.3.x on OSX 10.9 with macports for dependencies.

2.1 Install Dependencies

sudo port install gcc48 
sudo port select --set gcc mp-gcc48 
sudo port install openmpi-gcc48
sudo port select --set mpi openmpi-gcc48-fortran
sudo port install boost +openmpi
sudo port install cgal
sudo port install ccache
sudo port install flex
sudo port install scotch -mpich +gcc48 +openmpi
sudo port install metis +gcc48

And for completeness:

sudo port select --set llvm mp-llvm-3.5
sudo port select --set python python27 
sudo port select --set db db48

Note, before installing and upon running "port select --summary", you should get something that looks like this:

$ port select --summary
Name    Selected               Options
====    ========               =======
db      db48                   db48 none
gcc     mp-gcc48               mp-gcc48 none
llvm    mp-llvm-3.5            mp-llvm-3.5 none
mpi     openmpi-gcc48-fortran  openmpi-gcc48-fortran none
python  python27               python25-apple python26-apple python27 python27-apple none

2.2 Create a volume and mount it

hdiutil create -size 8.3g -type SPARSEBUNDLE -fs HFSX -volname OpenFOAM -fsargs -s OpenFOAM.sparsebundle
mkdir -p OpenFOAM
hdiutil attach -mountpoint $HOME/OpenFOAM OpenFOAM.sparsebundle
cd OpenFOAM
git clone
cd OpenFOAM-2.3.x

2.3 Get the patch


Or from here:

Download the above and place it in the OpenFOAM-2.3.x directory.

2.4 Apply the patch

Given that the patch was originally developed for OpenFOAM 2.3.x after a couple of days of the repository having started, we need to change back to the older commit in the 2.3.x git history, by running the following commands:

git checkout 081e976023a9b6c9cd0405cfb48d2acd6999f6e1
git checkout -b macosx

Then we can safely apply the patch:

patch -p1<OpenFOAM-2.3.x-Mac.patch

Now we can finish up the application of the patch by submitting the changed to the git tree, by running:

git add -u
git add wmake/rules/darwinIntel64* bin/
git commit -m "Applied patch"

2.5 Update the OpenFOAM-2.3.x/etc/bashrc

Append these lines to the /path/to/OpenFOAM-2.3.x/etc/bashrc (change the "/path/to" to whatever your fully qualified path would be):

echo "WM_CC=mpicc" >> /path/to/OpenFOAM-2.3.x/etc/bashrc
echo "WM_CXX=mpicxx" >> /path/to/OpenFOAM-2.3.x/etc/bashrc

Note: using the mpi wrappers (mpicc, mpicxx) revolves errors locating mpi header files, i.e. "mpi.h" - no sideffects were observed in the logs.

2.6 Apply fixes manually

If trying to compile on OSX El Capitain or newer, try to apply the fix indicated here: Error installing openfoam on El Capitan - post #4 - has the instructions for fixing an issue in building with Flex.

2.7 Install

source etc/bashrc && WM_NCOMPPROCS=$(sysctl -n hw.ncpu)
./Allwmake > log.Allwmake 2>&1

Note, you may notice this message:

"Proper OpenMPI not installed. Either do 'port install openmpi-mp' or 'port install openmpi-default'" 

Ignore it. Using mpicc and mpicxx wrappers will take care of includes and linking.

It might also complain about the ulimit, ignore this as well. (If you are on 10.9 and you try to change this, you will get an error anyway). Do the following instead, if needed:

Add this line:

limit maxfiles 16384 32768 



(create it if it does not exist, and restart to take effect)

2.8 Update your bash profile

Update your ~/.bash_profile to load the OpenFOAM bashrc file by adding:

if [ -f $HOME/OpenFOAM/OpenFOAM-2.3.x/etc/bashrc ]; then
  . $HOME/OpenFOAM/OpenFOAM-2.3.x/etc/bashrc

to your ~/.bash_profile (assuming you have mounted the volume, this will load the openfoam bashrc file and setup your environment).

All steps were taken from bash history file after compilation and testing.
