How to install OpenFOAM in Windows 10 and Ubuntu - 2021 and 2022

[@theansatz]

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]

What if you try only openfoam2106? Without -default

[@nuubxiii5278]

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!

Mine has a lot of info which grew historically, so differences are fine. Does it tell you that there is no bashrc file or no of installation?

How would I go about copying the "Allwmake META-INFO ThirdParty applications bin etc platforms src tutorials wmake" line into my home?

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.

Hello, Thanks for the tutorial. Will you be posting the Windows 11 installation video soon?

[@OpenFOAMJozsefNagy]

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.

[@matthiassinger3288]

Hello Jószef, thank you very much for your detailed installation guide. After I installed OpenFoam successfully I wanted to check the installation via the command foamInstallationTest. Although the base configuration is ok I receive 2 critical errors. Also, under "Software Components" it says that flex, make, wmake, gcc, g++ and icoFoam is not installed. Can I ignore these errors?

[@OpenFOAMJozsefNagy]

The question is, do you want to compile source code or just run cases? If blockMesh runs, it should be good for running cases. If you want to compile you need those packages.

[@matthiassinger3288]

@@OpenFOAMJozsefNagy Thanks for your reply. I also want to compile sources. The interesting thing is that I can compile sources, despite the fact that I get the errors. Yesterday noon I did some programming tutorials according to the video of Tom Smith ( kzbin.info/www/bejne/gXOceZudnLqclac ) and everything seemed to work fine. I was just confused at first that I did something wrong during the installation but OpenFoam seems to use wmake for compiling anyway.

Congratulations for the great video!

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?

[@rajinthss7732]

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.
