Hi everyone,
I would like to use OpenFoam for fluid modelling. Unfortunately I am new to linux and I have just made a new installation of the Ubuntu 8.10 64-bit. I am trying to find how exactly to install OpenFoam, but the installation guide in the openfoam web page (http://www.opencfd.co.uk/openfoam/linux64.html) is not very detailed. I' ve read several other guides but I still feel confused. Can someone who has installed it succesfully, please explain me the exact procedure of the installation? I have downloaded the 64-bit version of the openfoam and third party software. What else do I need to download? Also where can I find the Qt library 4.3.x.? In synaptic I only found the Qt4.4. Is there any detailed guide on the internet?
Any help will be appreciated.

Hi Fivos,

1 - Create the OpenFOAM main directory:
mkdir ~/OpenFOAM

2 - Unpack OpenFOAM-1.5.General, OpenFOAM-1.5.linux64, ThirdParty.General and ThirdParty.linux64 (in this order):
cd ~/OpenFOAM
tar xzf OpenFOAM-1.5.General.gtgz
tar xzf OpenFOAM-1.5.linux64GccDPOpt.gtgz
tar xzf ThirdParty.General.gtgz
tar xzf ThirdParty.linux64Gcc.gtgz

3 - Edit your ~/.bashrc file:
gedit ~/.bashrc
<add this at the bottom of the file>
. $HOME/OpenFOAM/OpenFOAM-1.5/etc/bashrc
<save the file and exit>

4 - Source the updated bashrc file:
. ~/.bashrc

5 - Test your OpenFOAM installation:
tut
cd icoFoam/cavity
blockMesh
icoFoam
paraFoam

Regards,
Jose Santos

Dear Jose Santos,
Could you please be more specific at the 4th step (4 - Source the updated bashrc file:
. ~/.bashrc)? How can I do that ?
First of all the bashrc file I have to modify is located at ~/OpenFOAM/OpenFOAM-1.5/etc
is that correct? After modifying that file I typed the command you mentioned
(. ~/.bashrc) but it does nothing, it says No such file or directory.
Any ideas for that?

Thanks in advance.

You do not have to edit the ~/OpenFOAM/OpenFOAM-1.5/etcbashrc file

do

3 - Edit your ~/.bashrc file:
gedit ~/.bashrc
<add this at the bottom of the file>
. $HOME/OpenFOAM/OpenFOAM-1.5/etc/bashrc
<save the file and exit>

In ubuntu 8.10 you'll have to actually create the ~/.bashrc file

then restart the terminal and run foamInstallationTest to check for missing software

have fun

About Qt: you shouldn't worry about 4.4, I was able to successfully build and run Paraview (the bundled version) even with Qt 4.4.3. When you run paraFoam you'll come to know whether Paraview is up and running fine.

Thanks everyone I installed it (the foam installation test doesnt give errors, so I hope it is ok).
