OpenFOAM-2.0.1 Installation & its dependency resolution
 
Hi,

I'm a system admin - trying to install OpenFOAM-2.0.1 on OpenSUSE-11.1 LINUX.
Can someone clear my doubts:

Is it possible to install mpi version of OpenFOAM without Paraview? Or is paraview a must pre-requisite for OpenFOAM?

If Paraview-3.10.1 is installed with binary distribution, then can I continue installing OpenFOAM-2.0.1(mpi version) from source distribution?


Thanks,
San

Greetings Sangamesh,

ParaView is usually only necessary for post-processing the results. So, it will depend on the usage scenarios:
  • If the machine(s) where you are installing OpenFOAM are for calculations only, then you don't need to install ParaView.
  • If one or more machines where you are installing are to be used as workstations, then ParaView should be installed.
  • If in case of a cluster, it will depend on the sizes of the simulation cases to the executed with OpenFOAM on the cluster. For example: if the cluster has got a total of 96GB of RAM, but the workstation has less than 96GB of RAM, then the cluster will also have to be used for post-processing; i.e., you must build ParaView with MPI as well.
As for your last question: currently the internal reader in ParaView 3.10.1 is not fully working with cases simulated with OpenFOAM 2.0. The next version of ParaView should have these problems fixed, but I don't know when it will be released.

Best regards,
Bruno

Thanks Bruno.

Do you have any idea which version of Paraview work with OpenFOAM versions?

Hi Sangamesh,

Mmm, I'm having some trouble trying to understand what you are trying to achieve... mainly because it's been a long week for me :)

AFAIK, the standard ParaView 3.10.1 can open simulation cases of OpenFOAM up to 1.7.x. ParaView 3.11 or 3.12 might open cases from 2.0 without any problems, or so I hope.

Either way, it's not very difficult to build ParaView 3.10.1 from source! You can follow these instructions to install it: Building ParaView 3.10.1 with custom Qt 4.6.4
If you need to install ParaView with Python and MPI as well, run:
Code:

./makeParaView -help
So you can see what's necessary.

Best regards,
Bruno
