As a new Linux user, I really appreciate the fact that you explained what bashrc is and what it actually does. I had a hard time finding out what this meant and why it is important, you're video has been very concise and helpful, thanks.
Thank you so much Cyprien, i am new to Linux and open-source software and was stuck since last few days. Your video helped me install the openfoam software properly and in devloping some understanding of Linux.
Very nicely explained sir. I installed successfully OpenFOAM 9 in ubuntu 20.04.3 by following your procedure. Thank you so much, hope you provide more tutorial from basics.

Hi, thank you for the helpful video. I have one question regarding running OpenFOAM via WSL on a Windows machine. I am thinking of buying a workstation. But I am not too familiar with ubuntu OS. So I just wondering what the limitation or difference when running OpenFOAM in WSL windows and pure ubuntu machines is?
In openfoam-11 version i am not being able to find many important solvers like pisofoam, icofoam etc how can i install them while i can see that it exists in openfoam version-8 and it can not be installed because of newer version please tell me how can i solve this problem please?

Sir there was a problem identified when I was getting started the problem is [Mesa Warning: Window 4823505 has no colour map ] What is the way to solve this thank you
Hello, Thank you for the wonderful tutorial, I am getting following message while running the example backward step flow. missing destination file operand after '/opt/openfoam9/tutorials/incompressible/simpleFoam/pitzDaily' Kindly help.
Check how the copy works in Linux. The syntax should be “cp -r path1 path2” You forgot path2 If you are copying in the current folder, then path2 is just a dot “.”
How are you running openfoam on windows? Do you use WSL to run Linux and installed openfoam on it? Mesa is some software used in Linux to emulate the graphic card to display stuff, so maybe you are getting this warning because the graphic card is not installed or detected. That’s just a guess as you didn’t provide much information
Hello, Thank you so much for the video :). I have a problem with paraview (PV) where I cannot access my data files that I have created using OpenFoam (OF). I have followed tha installation steps at the OP website. Your method of installing OP is a bit different than that of the creator website.
Perfect video and it went all smooth for me until at 19:97 when I launch paraFoam then I get the following error message in my Ubuntu 20.04.6 LTS Created temporary 'pitzDaily.OpenFOAM' Mesa warning: Window 6291465 has no colormap!

## urgent to know I want to simulate a rotation with complex interactions between the item and viscous liquid. Specifically, that is problem 9 in 2020 IYPT. Is Openfoam proper to do that? Or any advice for a better software? Thanks.
You’re talking about magnetic levitation? I don’t think Openfoam can simulate electromagnetic physics. Not sure if any software has electromagnetic-fluid interactions… fluent?
@@Feaforall : Never used OpenFOAM but I am sure COMSOL does it. And EM can be applied through Maxwell equations or there are other ways as well. Should be done through OpenFOAM as well.
Hello when i exicute simpleFOAM I have this comment in addition FOAM FATAL ERROR: Wrong number of arguments, expected 0 found 1 is this an installation problem ?
I cannot open paraview.

Does anyone know how to fix this?
Looks like you are on a machine which doesn’t have a X Server, so paraview can’t open its graphic window. Are you on a virtual cloud machine? Or are you on the windows bash ? In the first case, you can install a special version of paraview with Mesa to use paraview without X server ( that’s a bit complex to set up but doable). In the 2nd case, you can install the windows version of paraview and open your openfoam results in windows/paraview rather than using the paraview version shipping with openfoam.
@@Feaforall Thanks for your response. However I still dont really get it. I am working with ubuntu 18.04. I also installed paraview in ubuntu with the following command: sudo apt-get update && sudo apt-get install paraview. And i also installed a windows version of paraview. But how can i use paraview now with openfoam?

Can OpenFOAM install in ubuntu 20.04? When I install in ubuntu 20.04, I am prompted to fail to compile, this is because the version??
Yes, I am sure you can install openfoam in Ubuntu 20.04. Look at the error and try to solve it. Maybe you lack a software dependency or a compiler.
