I recently purchased a Mac-Book Pro 13'' 2012 Model, an old model but functioning as good as new. Getting a Mac for myself was in my bucket-list and finally I own it now.
Now the First Task was to Install OpenFOAM on this and let me tell you it wasn't easy at all. And finally after almost a week's struggle I have finally been able to Install it on Mac and that too the latest version of OpenFOAM 4.0 with Paraview-5.1.0 !!!!!
As it was a good long struggle for me and since there is no one stop solution for installation let me help you with the Installation. Here are the steps for installing OpenFOAM on Mac OS.
1. Install the homebrew package (
brew.sh ). This basically is like a onestop package manager for all the dependencies required for Installing OF.
2. Now Install these packages one by one
$ brew tap hombre/science
$ brew install open-mpi --disable-fortran
$ brew install scotch
$ brew install cgal
$ brew install flex
$ brew install boost --without-single --with-mpi
$ brew install metis
$ brew install parmetis
$ brew install https://raw.githubusercontent.com/mrklein/openfoam-os-x/master/formulae/parmgridgen.rb
3. Once done with Installing all these packages ( would take about and hour or more depending on your Internet speed ), Download the latest version of OpenFOAM tar file from the OpenFOAM website or git or bitbucket.
4. Create a disk image using the CLI interface from the command shown below.
$ hdiutil create -size 8.3g -type SPARSEBUNDLE -fs HFSX -volname OpenFOAM -fsargs -s OpenFOAM.sparsebundle
Size key specifies size of the image, as usually I keep all OpenFOAM versions on one image, the size is rather large but as it is sparse image, its size will grow as necessary (for example size of disk image with 6 different OpenFOAM versions is around 6G). Type of the disk image is Sparse bundle as it is more convenient for backup software. Volume name is OpenFOAM, you can change it to anything you like. File system type is set with -fs flag, in the command it is just extended HFS, if you'd like, you can add J letter there to get journaling. And finally -fsargs -s supply -s option to newfs utility that forces it to create case sensitive file system.
5. Mount the Disk Image
First create a directory with the name OpenFOAM
$ mkdir -p OpenFOAM
Now mount the disk image on the newly created folder
$ hdiutil attach -mountpoint $HOME/OpenFOAM OpenFOAM.sparsebundle
6. Extract the tar file into your OpenFOAM directory in home folder
$ cd OpenFOAM && tar xzf ~/Download/OpenFOAM-4.x.tgz
7. Download the Mac OS patch for the specific version you are using and move it into OpenFOAM-4.x directory in your OpenFOAM folder in $HOME
$ cd OpenFOAM-4.x && curl -L https://raw.githubusercontent.com/mrklein/openfoam-os-x/master/OpenFOAM-<VER>.patch > OpenFOAM-<VER>.patch
Here VER refers to your version number
8. Apply the downloaded patch
$ git apply OpenFOAM-4.0.patch
9. Building OpenFOAM
Follow these few steps before you start compiling OpenFOAM
$ mkdir -p $HOME/.OpenFOAM
$ echo 'WM_COMPILER=Clang' > $HOME/.OpenFOAM/prefs.sh
$ echo 'WM_COMPILE_OPTION=Opt' >> $HOME/.OpenFOAM/prefs.sh
$ echo 'WM_MPLIB=SYSTEMOPENMPI' >> $HOME/.OpenFOAM/prefs.sh
$ echo 'export WM_NCOMPPROCS=$(sysctl -n hw.ncpu)' >> $HOME/.OpenFOAM/prefs.sh
$ echo 'export WM_SILENT_RULES=Y' >> $HOME/.OpenFOAM/prefs.sh
$ echo 'WM_LABEL_SIZE=32' >> $HOME/.OpenFOAM/prefs.sh
$ source etc/bashrc
$ [ "$(ulimit -n)" -lt "4096" ] && ulimit -n 4096
$ ./Allwmake > log.Allwmake 2>&1
COMPILATION will take about 2-3 hours
10. Testing your Installation
You can check your Installation with the regular way, by typing icoFoam -help and look out for the message or by typing
foamInstallationTest
This basically checks if all the packages are configured properly by OpenFOAM during compilation
11. Setting up Environment Variable
Sourcing OpenFOAM bashrc file each and every time you login to your system can be quite boring and time consuming. To avoid this copy past these lines into a file named as :
openfoam-env-setup.sh and save this on your $HOME folder. Source this file into .profile in your terminal by typing source $HOME/openfoam-env-setup.sh
#!/bin/sh
# If you'd like to setup environment every time terminal is launched
# create .OpenFOAM/OpenFOAM-release file in your home folder. In the file put
# the string with a version you'd like to use. This can be done with:
# $ mkdir -p .OpenFOAM
# $ cat '2.X.Y' > .OpenFOAM/OpenFOAM-release
# If you'd like to switch environment between versions use of2xy commands.
readonly FOAM_MOUNT_POINT="${FOAM_MOUNT_POINT:-"$HOME/OpenFOAM"}"
readonly FOAM_RELEASE_FILE="${FOAM_RELESE_FILE:-"$HOME/.OpenFOAM/OpenFOAM-release"}"
readonly FOAM_DISK_IMAGE="${FOAM_DISK_IMAGE:-"$HOME/OpenFOAM.sparsebundle"}"
mount_disk_image () {
local oldpwd="$(pwd)"
cd "$HOME"
# Attempt to mount image
hdiutil attach -quiet -mountpoint "$FOAM_MOUNT_POINT" "$FOAM_DISK_IMAGE"
cd "$oldpwd"
return 0
}
main () {
[ -f "$FOAM_RELEASE_FILE" ] || return 1
local release="$(cat "$FOAM_RELEASE_FILE")"
local bashrc="$FOAM_MOUNT_POINT/OpenFOAM-$release/etc/bashrc"
[ -f "$bashrc" ] || mount_disk_image
if [ -f "$bashrc" ]
then
source "$bashrc" WM_NCOMPPROCS="$(sysctl -n hw.ncpu)"
else
echo "OpenFOAM $release doesn't seem to be installed."
fi
}
# Reset environment variables for specified version
ofxxx () {
local release="$1"
[ -n "$WM_PROJECT_DIR" ] && . "$WM_PROJECT_DIR/etc/config/unset.sh"
local bashrc="$FOAM_MOUNT_POINT/OpenFOAM-$release/etc/bashrc"
if [ -f "$bashrc" ]; then
source "$bashrc" WM_NCOMPPROCS="$(sysctl -n hw.ncpu)"
else
mount_disk_image
if [ -f "$bashrc" ]; then
source "$bashrc" WM_NCOMPPROCS="$(sysctl -n hw.ncpu)"
else
echo "OpenFOAM $release doesn't seem to be installed."
fi
fi
}
of22x () {
ofxxx "2.2.x"
}
export -f of22x
of231 () {
ofxxx "2.3.1"
}
export -f of231
of23x () {
ofxxx "2.3.x"
}
export -f of23x
of240 () {
ofxxx "2.4.0"
}
export -f of240
of24x () {
ofxxx "2.4.x"
}
export -f of24x
of300() {
ofxxx "3.0.0"
}
export -f of300
of301() {
ofxxx "3.0.1"
}
export -f of301
of30x() {
ofxxx "3.0.x"
}
export -f of30x
of40() {
ofxxx '4.0'
}
export -f of40
of4x() {
ofxxx '4.x'
}
export -f of4x
ofdev() {
ofxxx "dev"
}
export -f ofdev
pf () {
paraFoam -builtin > /dev/null 2>&1 &
}
main
12. Restart Terminal !!!!
Now every time you start the terminal just type the alias related to your version
eg. of40
Now, this is for all the MAC users. Do not install packages Macports, it will create issues while compilation since we have installed packages from brew. ( from personal experience )
