Hello Sir, I'm new in the Linux environment too. I'm having issues with the package installation of OpenFoam. I completed the first two steps (enable wls and install ubuntu). I installed Ubuntu 20.04 LTS. After the curl and wget commands i get "The repository is setup! You can now install packages." After that, I paste the command sudo and i get "E: Unable to locate package openfoam2106-default". I tried the "apt-get update" command too. I honestly don't know what I'm missing, so I wish you could suggest me on how to solve this. Thank you for your videos, and your support.
@@OpenFOAMJozsefNagy I have the same problem as the commenter above. I tried removing “-default” but it’s still says unable to locate package openfoam2106. I still really appreciate your help and your constant replies to people. Your help is much appreciated!

Dear sir, after installation openfoam in windows 10, the command( cp - /usr/lib/openfoam/openfoam2106/tutorials/incompressible/sipleFoam/ ) that you have used is not working, the answwer i got is ( No such file or directory) , then how to do tutorials guide me please
Hello. I am a mechanical engineer student and I am using openfoam in my master thesis. I followed this video at the end but I need to work with dsmcfoam. Can you tell me if this is included in the openfoam installed? I really need your help in this because I can't find this information in internet
Thanks a lot to you, your videos are very helpful for me to understand the basis of OpenFOAM, I like your way of explaining. Can you please make a video on "Laser DTRM"?
Sorry for the English, but my French is not the best. You can open up the .bashrc file in any other text editor of your choice (emacs, vim, gedit, notepad++ in windows). I hope this helps.
First I have to purchase a Win11 Laptop to fully recreate the fresh install of WSL in Win11, so this will be in January. But all you really have to do is open the new "Windows terminal" (not cmd!) and type in "wsl --install". Then you will get a Ubuntu and can install openfoam just like I show here.
Hey Jozef, my bashrc file looks very different from yours and after pasting the line for the usr lib and saving it tells me there is no such file or directory. Do you happen to know why they would look so different? im on ubuntu 20.04 and downloaded the 2106 open foam successfully. Thanks for all the videos!
How would I go about copying the "Allwmake META-INFO ThirdParty applications bin etc platforms src tutorials wmake" line into my home? I believe this is why I am not able to run the tutorial you started at 09:20. I heard the phrase "copy to your home" a few times but I'm not sure how to actually do so. Any help would be much appreciated!
Thank you very much for this great tutorial. In the part where we need to write the line /usr/lib/openfoam/openfoam2212/etc/bashrc into our bashrc I got confused and I am not sure if the installation has been successful, since I am receiving the message: Permission Denied. Could you please explain how you wrote this line into your bashrc?
Dear Sir, I am using WSL Ubuntu22.04.2 on my Windows 10. I have downloaded the paraview from the official website to my home directory. However, when I run the 'paraview' command from Ubuntu for my .foam file, it does not work and give me an error of 'paraview: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory'. I tried to use the sudo apt-get command for the paraview installation as well and run the 'paraview' command again, but it is still not working. Wondering if you know the issues about this? Appreciate for your guidance.
Congratulations for the great video! I followed the proposed steps successfully up to 8:50 when I wrote: . /usr/lib/openfoam/openfoam2212/etc/bashrc^C, and the error message was: No such file or directory. I ignored this error and went on, until the point that I wrote: cp -r /usr/lib/openfoam/openfoam2212/tutorials/incompressible/simpleFoam/, and the error message was this time: cp: missing destination file operand after '/usr/lib/openfoam/openfoam2212/tutorials/incompressible/simpleFoam/' What should I do next given I am not experienced at all in Linux?
You should include the "." after your command (without the quotation marks), which tells the system to copy the files into your "current" path. Without it, you will get the missing destination error.
