Hello!


I'm pretty new to Ubuntu and Openfoam, and I am currently trying to get the first Openfoam tutorial to work.



I am running Ubuntu 18.04 on Windows 10, Openfoam6, Paraview5.4/5.6 (more on this later), and I have Xming installed for displaying a GUI when I use paraFoam command



I have followed the instructions for installation from the Openfoam website, and everything about Openfoam seems to work nicely: blockMesh and simpleFoam both work perfectly.

However, when I use the command "paraFoam" it returns this:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-neil'
failed to get the current screen resources
Xlib:  extension "MIT-SHM" missing on display "localhost:0.0".

I trolled around on these forums and found this from a post in January:


paraview 5.6 on Ubuntu 18.04 (Windows 10 WSL)



This user has the same problem as I, and another user responds saying:

I feel like I must apologize for allowing this to happen, but I haven't had time to contribute in order to avoid from this happening in the first place

The simplest solution is to go back in time, namely to install an older OpenFOAM 6 Deb package that still binds to ParaView 5.4.0, until this issue is sorted out. This can be done with the following commands:

If I am correct, he is saying that Paraview 5.6 does not work with Openfoam 6?



I followed his instructions, replacing paraviewopenfoam56 with paraviewopenfoam54; however, if I try to run paraFoam I get this:

FATAL ERROR: ParaView reader module libraries do not exist

Please build the reader module before continuing:
cd $FOAM_UTILITIES/postProcessing/graphics/PVReaders
./Allwclean
./Allwmake

I then did

 paraFoam -builtin

which returned

Created temporary 'pitzDaily.foam'
/opt/openfoam6/bin/paraFoam: 278: /opt/openfoam6/bin/paraFoam: paraview: not found

I have spent many hours troubleshooting with Ubuntu and Openfoam as a new user, and this seems to be the final challenge to overcome! I would really appreciate any help on this topic.

Thanks!
