I am trying to install openFoam on Mac OS X 10.10.5 (http://www.openfoam.com/download/install-binary.php) by using Docker-toolbox. I can do without problems all the suggested steps, but then, when I try to run the example included in the installation guide, I cannot open paraFoam, since it returns the following error:

paraview: cannot connect to X server
I have also installed XQuartz but it doesn't seem to help much!

Didn't try myself but a Google Search brought me to:

I was able to use Quartz to launch paraFoam in Mac but In Mac using XQuartz affect performance of GUI i.e it took long time . It would be better if you install paraview separately and use it . http://www.paraview.org/download/

Disclaimer: Never used Docker.


For better performances there's also: x2go. There is a port also on macports, I don't know on Homebrew.

If you can install the server on the Docker it should perform better than X11 forwarding (ssh -X ...)

I have installed Paraview on my computer and I have docker running openfoam.
How does one go about using paraview with docker?
How do I locate the file I need to open in paraview since the docker files are not visible in Finder?
I can't seem to locate the docker files in Finder. When I open Paraview, what file should I be opening?

This answers seems to help: http://stackoverflow.com/questions/3...n-os-x-part-ii

But, I am still not sure how to go about getting the cd function to work to get me to the folder.

Scenario 1:
When I type open -a paraview foam.foam within the docker shell, I still get the error:
bash: open: command not found

Scenario 2:
When I open a new terminal tab and type in the commands from the website, I get this error:
"ERROR: In /Users/kitware/buildbot-slave/paraview-bigmac-osx-shared-release_opengl2_osx10_7_qt4_superbuild/build/paraview/src/paraview/VTK/IO/Geometry/vtkOpenFOAMReader.cxx, line 8483

Hi..

1.Scenario 1: is not good for you.

2. You need to create foam.foam file inside the testcase that you are runnning .
See below explanation

Looks OpenFOAM is for running the case i.e meshing and doing simulation . Paraview is for post-processing . You need to run case in via docker terminal box i.e OpenFOAM via docker terminal box only.

Lets suppose you copied
mkdir -p $FOAM_RUN
run
cp -r $FOAM_TUTORIALS/incompressible/icoFoam/cavity .
cd cavity
blockMesh
icoFoam

This will create a folder with name OpenFOAM in your home directory i.e /Users/daniel (assuming daniel is your username ) . Go inside the folder docker-v3.0+(if you are using latest script that i have provided) and then inside run directory and your cavity folder is in same location. When you launch paraview , you need to browse to this folder and open a.foam (i.e assuming your created a.foam file using command touch a.foam inside the cavity folder.)

Note:I added new script which can be found in this link (name of script is installOpenFOAM_MAC_pgh.gz which help in resolving some issue related to file read/write permission in MAC

Thank you for that explanation. I didn't realize that I need to look for OpenFOAM folder. I kept looking for FOAM_RUN folder. Thank you. This helps a lot!

Hi pgh,
I am a beginner to OpenFOAM. How to open paraView through docker?

For now, I don't find the direct solution. What I did is create a new "test.foam" file in the same folder, and open it using paraView. But is there a way that I can just use "paraFoam" to open the paraView?

Thanks.

hi Siyu

Right now , in Mac , we suggest to use paraview . . paraFoam is same as paraview but has some additional capability . Since you are beginner , i think it should not make much difference to you
To use paraFoam is mac, right now is a bit complicated and graphics wise experience is not good .

Thanks

Hi,

I am using macOS Big Sur v.11.4 and using docker to run openFOAM v1906. However, when I type paraFoam in the bash, the following error appears.
OpenFOAM is running fine but I cannot load ParaVEW. I have preview running spepratley file. But I cannot load my case. Any help in this regard will be highly appreciated.

QXcbConnection: Could not connect to display host.docker.internal:0.
Aborted

Regards,

[olesen]

If you use a newer openfoam-docker starter
specifying the '-X' option should do.
https://develop.openfoam.com/packagi...penfoam-docker

However you should be using a native (osx) version of paraview and not be using 'paraFoam' with docker
