I have installed OpenFoam-2.3.0 on Centos-6.5 according to the official guide. It is stated that the final command to run is of230, however, that command has no output.

It seems that the command should be icoFoam (and that is partially stated in the guide).

mahmood@cluster:~$ cat .bashrc
alias of230='module load openmpi-x86_64; source /export/apps/mechanics/OpenFOAM/OpenFOAM-2.3.0/etc/bashrc WM_NCOMPPROCS=4 foamCompiler=ThirdParty WM_COMPILER=Gcc48 WM_MPLIB=SYSTEMOPENMPI'

mahmood@cluster:~$ source .bashrc
mahmood@cluster:~$ of230
mahmood@cluster:~$ icoFoam --help

Usage: icoFoam [OPTIONS]
options:
  -case <dir>       specify alternate case directory, default is the cwd
  -noFunctionObjects
                    do not execute functionObjects
  -parallel         run in parallel
  -roots <(dir1 .. dirN)>
                    slave root directories for distributed running
  -srcDoc           display source code in browser
  -doc              display application documentation in browser
  -help             print the usage

Using: OpenFOAM-2.3.0 (see www.OpenFOAM.org)
Build: 2.3.0-f5222ca19ce6



--> FOAM FATAL ERROR:
Invalid option: --help


FOAM exiting

mahmood@cluster:~$

Any idea on that?

Sorry for not making it clearer on the wiki page, but the idea is that when this command of230 runs, it will only show output if there is an error. Therefore, it probably worked as intended.

icoFoam is one of the solvers in OpenFOAM. Since you ran:

icoFoam --help

it gave an error message at the end, stating that the option "--help" doesn't exist. The correct option is "-help", as indicated on the wiki page

It seems that OpenFOAM 2.3.0 is now installed without any problems. Please start reading the OpenFOAM User Guide, as stated at the end of the instructions:

18. Now you can go read the User Guide: official OpenFOAM User Guide

Thank you very much. Indeed, I am not an expert in OpenFoam. Instead, as the administrator of the cluster, I installed it for the users.

One more question:
Is there a big difference between 2.2 and 2.3? Are the scripts and commands compatible? I mean from 2.2 to 2.3.

I will ask my next question in a new topic

For the most part, the two are compatible, but only conceptually.
What I mean is that there are some considerable changes all the way from 2.2.0 to 2.3.0, although most only affect how the simulation cases are prepared for running.

You can ask your users to go through the Release Notes for each version so that they can tell you what they need. You can find a complete list of links to the release notes at the top right corner on this page: http://openfoamwiki.net/index.php/Main_Page

You might want to provide OpenFOAM 3.0.1 as well to your users, given that this is the most recent version. Instructions are provided here: https://openfoamwiki.net/index.php/I...HEL#CentOS_6.7

OK thank you very much for the helps.
