Hi There
I'm trying to install OpenFOAM 2.3 on a 5 node cluster running Centos 6.4. I've followed the guide at https://openfoamwiki.net/index.php/I...CentOS_SL_RHEL based on Centos 6.5, but I've adjusted my $HOME to point to /opt. The reason for doing this is that the /opt directory is a network shared directory --- the plan is to install OpenFOAM once on a single node and then to simply run it from the others. I have however run into errors that I can not resolve. See attached make.log file. Any help would be appreciated. |

Hi Elvis
I managed to get OpenFOAM running properly in the NFS folder by first installing it in my home directory and then moving the OpenFOAM folder to the desired place. I followed wyldckat's instructions from #5 found here http://www.cfd-online.com/Forums/ope...tml#post361663. On an unrelated note: when I ran my simulation I kept running into this error: Code:
Setting up information for layer truncation ... new cannot satisfy memory request. This does not necessarily mean you have run out of virtual memory. It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library new cannot satisfy memory request. I think this may have been caused by the NFS folder only being on a 50GB partition... :P Unfortunately I can't run my simulation again. See log file for details. bmw_snappy.log.tar.gz |

Greetings to all!
@Colin: I'm sorry to say that the error message was due to a rookie mistake: Code:
/*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.3.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 2.3.0-f5222ca19ce6 Exec : snappyHexMesh -overwrite The result was that you had X processes, all trying to create the same mesh, requiring X*N memory in total, instead of just N for the whole parallel mesh generation. Best regards, Bruno
