OpenFoam 1.7 Installation
 
Hello!

I'm currently trying to reinstall OpenFoam using version 1.7.0 on OpenSuse 11.2.
There were no problems with version 1.6 until I close the terminal window. The pathways to use for example blockMesh are then no longer there. So I hope that version 1.7.0 will no longer have this problem. However, I'm now having problems sourcing bashrc.

After unpacking the files I will go into the $HOME/.bashrc by typing:

vi $HOME/.bashrc

I added the following line:

#export PILOTPORT=/dev/pilot
#export PILOTRATE=115200

.$HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc <------

type esc, then :wq to write and quit the editor.

From there the installation guide asks you to type

.$HOME/.bashrc

into the terminal window (within /etc directory). However, when I do this it states the directory does not exist.

Any ideas would be appreciated!

Cheers

Robyn

Greetings Robyn and welcome to the forum!

OK, a little explanation: the dot, in this case, at the beginning of the command line does the same thing as the "source" command. When the dot at the beginning of a command line is the command itself, then a space must be put in between the dot and the rest of the command line ;)

So, what you should have in your $HOME/.bashrc file (in this case, the dot is part of the file name and that this file should be hidden) is this:
Code:

. $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc
Notice the space between the dot and $HOME! This way the file is properly sourced.

Now, you can either start a new terminal or run this command (anywhere, doesn't need to be in the /etc folder):
Code:

. $HOME/.bashrc
Again, notice the space between the dot and $HOME!

Now, you might ask "what does it mean to source a file?" Well, it means that the file is not to be just executed as a script, but it should be executed as if it were a function that updates your current shell environment! And that's how the OpenFOAM environment gets set-up and ready to go :D

Best regards,
Bruno

Hi Robyn,

Well, OpenFOAM 1.7 only has a prebuilt version for Ubuntu. So I'll have to refer you now to this thread: http://www.cfd-online.com/Forums/ope...-2-11-3-a.html
It has links to instructions on how to build OpenFOAM 1.7 in OpenSUSE 11.2 and 11.3 :)

Best regards,
Bruno

Hello Bruno,

Thanks for the link. I think I might be missing a line in my $HOME/.bashrc file as before there was a test true... at the end of the file I forgot that I deleted. Could this potentially be the problem as the wmake step is not found.

Regards,

Robyn

Thanks Bruno, I will work on it and see where it goes.

Do you know where I could still retrieve a copy of OF 1.6 ? As I was beginning to build my own cases and would not like to be stuck in this position for long.

Regards,

Robyn

Hi Robyn,

OpenCFD's repository for OpenFOAM files is this: http://sourceforge.net/projects/foam/files/
You can get from there all OpenFOAM's since 1.1 :D

Best regards,
Bruno
