Hi all,

I am fairly new with openFoam and I am trying to find my way through. I have installed the latest version of openFOAM OpenFOAM-v1812 following the guidelines from here:https://www.openfoam.com/download/in...binary-mac.php

The installation was smooth and I was able to run perfectly the cavity tutorial (I can see the progress on the screen and the results in the directory). My problem is when I try to run paraFoam.

What I initially got was (an apparently common problem)
$ paraFoam
$ Created temporary 'cavity.OpenFOAM'
$ QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-ofuser'
$ QXcbConnection: Could not connect to display
$ /opt/OpenFOAM/OpenFOAM-v1812/bin/paraFoam: line 312: 836 Aborted paraview

I then followed the guidelines from here: ParaView command not found

and I now get a problem with some libraries
$ /opt/OpenFOAM/ThirdParty-v1812/platforms/linux64Gcc/ParaView-5.6.0/lib/paraview: error while loading shared libraries: libmpi.so.12: cannot open shared object file: No such file or directory

Do I need these mpi libraries for this?

thanks a lot in advance!

The 'paraFoam' command is just a simple wrapper script. Just use a native paraview directly.

Paraview does not open it. The PitzDaily tutorial.
It requires the selection of a reader.
No one works.

Same error in Linux SUSE SLES

[aerothermal]

I managed to make paraFoam work in MacOSx after the installation of Paraview. Now I can use Paraview or ParaFoam.

ParaFoam is slower than Paraview.

To use Paraview I had to change the extension .OpenFoam to .foam

However, in SUSE SLES 15 Paraview does not work after installation. It appears to be a conflict between the OpenGL in the software and the NVIDIA driver of the OS.

And I cannot install the new driver from NVIDIA because it says that GUI or NVIDIA persistenced or smi is being used.

Without editing any files
"paraFoam -vtk"

After upgrading from ubuntu-20.04.6-desktop-amd64 to Ubuntu 22.04 LTS, the command (OpenFOAM11) stopped working: paraFoam –
"root@kol:/home/cavity# paraFoam

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
