1 Introduction
This page is dedicated to explaining how to install OpenFOAM in Ubuntu.
If you do not yet feel comfortable using Linux, then perhaps you better first read the page Working with the Shell and train a bit with the shell/terminal environments, so you can have a better perception of the steps shown below.
2 Copy-Paste steps
A few notes before you start copy-pasting:
- Lines that start with # don't have to be copy-pasted. They are just comments to let you know what's going on.
- One wrong character is enough for breaking this guide, so make sure you can read the characters properly or that the installed language system does not break the copied characters!
2.1 Ubuntu 12.04
Warning: These instructions are still being written!
Discussion thread where you can ask questions about these steps: none so far.
Steps:
- Note: Given the age difference of OpenFOAM 1.6 vs Ubuntu 12.04, these instructions will install the ParaView version that Ubuntu provides.
- Switch to root mode (administrator) and install the necessary packages (run one line at a time):
sudo -s #or su - #these 2 lines count as a single line, due to the blackslash "\" character apt-get install libglib2.0-dev build-essential flex bison libreadline-dev libncurses-dev paraview #if you have Ubuntu 64bit (see step #4) apt-get install libc6-dev-i386 exit
- Download and unpack (here you can copy-paste all in single go):
#OpenFOAM downloading and installation cd ~ mkdir OpenFOAM cd OpenFOAM wget "http://downloads.sourceforge.net/foam/OpenFOAM-1.6.General.gtgz?use_mirror=mesh" -O OpenFOAM-1.6.General.tgz wget "http://downloads.sourceforge.net/foam/ThirdParty-1.6.General.gtgz?use_mirror=mesh" -O ThirdParty-1.6.General.tgz tar xzf OpenFOAM-1.6.General.tgz tar xzf ThirdParty-1.6.General.tgz
- For building OpenFOAM itself, it depends on whether you have installed the i386 or x86_64 architecture of Ubuntu. To check this, run:
uname -m
Now, accordingly:
- For i386:
#update rules' files #wget "https://raw.github.com/OpenFOAM/OpenFOAM-2.1.x/master/wmake/rules/linuxGcc43/c" -O wmake/rules/linuxGcc/c #wget "https://raw.github.com/OpenFOAM/OpenFOAM-2.1.x/master/wmake/rules/linuxGcc43/c++" -O wmake/rules/linuxGcc/c++ #fix the rules' files #sed -i -e 's/gcc/\$(WM_CC)/' wmake/rules/linuxGcc/c #sed -i -e 's/g++/\$(WM_CXX)/' wmake/rules/linuxGcc/c++ #here you can change 4 to the number of cores you've got echo export WM_NCOMPPROCS=4 >> $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc #we're building the 32bit version sed -i -e 's/WM_ARCH_OPTION:=64/WM_ARCH_OPTION:=32/' $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc #This is a hack for modern 32bit Ubuntu (http://www.lukedodd.com/?p=225) echo 'export LIBRARY_PATH=/usr/lib/i386-linux-gnu' >> $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc echo 'export C_INCLUDE_PATH=/usr/include/i386-linux-gnu' >> $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc echo 'export CPLUS_INCLUDE_PATH=/usr/include/i386-linux-gnu' >> $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc source $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc echo "source $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc" >> $HOME/.bashrc
- For x86_64:
#update rules' files #wget "https://raw.github.com/OpenFOAM/OpenFOAM-2.1.x/master/wmake/rules/linux64Gcc43/c" -O wmake/rules/linux64Gcc/c #wget "https://raw.github.com/OpenFOAM/OpenFOAM-2.1.x/master/wmake/rules/linux64Gcc43/c++" -O wmake/rules/linux64Gcc/c++ #fix the rules' files #sed -i -e 's/gcc/\$(WM_CC)/' wmake/rules/linux64Gcc/c #sed -i -e 's/g++/\$(WM_CXX)/' wmake/rules/linux64Gcc/c++ #here you can change 4 to the number of cores you've got echo export WM_NCOMPPROCS=4 >> $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc #This is a hack for modern 64bit Ubuntu (http://www.lukedodd.com/?p=225) echo 'export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu' >> $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc source $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc echo "source $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc" >> $HOME/.bashrc
- For i386:
- Now to do several more necessary fixes:
#Go into OpenFOAM's main source folder cd OpenFOAM-1.6 #because we're using Ubuntu's ParaView sed -i -e 's=\.OpenFOAM=\.foam=' bin/paraFoam #adjust to modern times sed -i -e '/include $(GENERAL_RULES)\/java/d' wmake/rules/General/standard sed -i -e 's=/lib/cpp $(GFLAGS)=cpp -traditional-cpp $(GFLAGS)=' wmake/rules/linuxGcc/general sed -i -e 's=/lib/cpp $(GFLAGS)=cpp -traditional-cpp $(GFLAGS)=' wmake/rules/linux64Gcc/general #Remove all stupid comments from "Make/options" files find . -name 'options' | grep 'Make/options' | xargs sed -i -e '/^\/\//d'
- Have to build Gcc 4.3.3 from source, because Ubuntu 12.04 doesn't have it:
#Go into the ThirdParty folder cd ../ThirdParty-1.6 #Let's get a special compiler script wget -c http://original.nucleation.googlecode.com/hg/build-gcc_v4.tar.gz tar -xzf build-gcc_v4.tar.gz #And this is going to build Gcc 4.3.3, along with everyone that is needed ./build-gcc43 > gccmake.log 2>&1 #You can track the current progress in another terminal, by running: # tail -F $PWD/gccmake.log
- Now let's build OpenFOAM:
(Warning: this may take somewhere from 30 minutes to 6 hours, depending on your machine.)
#Go into OpenFOAM's main source folder cd OpenFOAM-1.6 # This next command will take a while... somewhere between 30 minutes to 3-6 hours. ./Allwmake > make.log 2>&1 #Run it a second time for getting a summary of the installation ./Allwmake > make.log 2>&1
- To check if everything went well:
#Check if icoFoam is working icoFoam -help #Edit the file "make.log" and check if there are any error messages #Example: gedit make.log #Create a tarball in case you've seen any errors (it's the first error that matters) #or if you don't understand the output #and attach the file "make.log.tar.gz" to a post in the designated thread tar -czf make.log.tar.gz make.log
- Now you can go read the User Guide, which is located at $HOME/OpenFOAM/OpenFOAM-1.6/doc/Guides-a4/UserGuide.pdf.
Discussion thread where you can ask questions about these steps: none so far.
