I am really new to programming and new to linux and new to OpenFOAM. I wasn't sure where to post this question on this board I hope its the right place.
I have been trying to do tutorial 2.2 on Openfoam.com's website.
I typed in ls $FOAM_TUTORIALS/basic/potentialFoam/cylinder and that worked correctly. But then I typed in blockMesh afterward to generate the mesh but it gave me these results below. I did a couple of other tutorials and they worked successfully but this one gave me these results after I typed in blockMesh. Is there something i'm forgetting? I am using Bash Ubuntu 20.04 with OpenFOAM 1912 on windows 10.

Hello,

Try to copy to your run folder.

cp -r $FOAM_TUTORIALS/basic/potentialFoam/cylinder $FOAM_RUN

Then change to that folder, cd to case folder (cylinder), and run blockMesh.

Foundation version of OpenFOAM will not let the user run the built-in tutorial in it's installed folder because it protects the built-in tutorials.

[Kendawgg22]

I was able to generate the blockMesh for two other tutorials the pitzDaily and the Cavity tutorial without using cp -r to copy to my run folder. I'll give it a try though.

[Kendawgg22]

When I typed that command line "cp -r $FOAM_TUTORIALS/basic/potentialFoam/cylinder $FOAM_RUN" I received an error
"ls: cannot access '/home/kendawgg22/OpenFOAM/kendawgg22-v1912/run': No such file or directory/home/kendawgg22/OpenFOAM/OpenFOAM-v1912/tutorials/basic/potentialFoam/cylinder/:"

I'm wondering if I can type "cp -r $FOAM_TUTORIALS/basic/potentialFoam/cylinder ." in order to copy it to the desktop. Is that doing the same thing?

Do you have a OpenFOAM directory with a run run directory? You need one.

[Kendawgg22]

I don't have one. I don't have a clue how to create one. I was able to run the blockMesh for two other tutorials the pitzDaily and the cavity tutorial for some reason. Is it just for the cylinder tutorial that this is required?

It is a common directory set up to keep files related to OpenFOAM.

mkdir OpenFOAM

cd OpenFOAM

mkdir run

Then you can cd to the run directory and use:

cp -r $FOAM_TUTORIALS/basic/potentialFoam/cylinder .

Back from my break. I tried those commands and I got the same error when I typed blockMesh again. I did two other tutorials and they worked just fine.

[Kendawgg22]

I tried using those commands to create the run directory and i still got the same error after i typed in blockMesh. I can also still do two other tutorials and they work just fine.

[HappyS5]

Hello,

Scroll down from installation to "Getting Started". Try to setup and run pitzdaily. https://openfoam.org/download/8-ubuntu/

[Kendawgg22]

Thank you for your help sir. But it turned out that I was missing some lib files that I needed to download in order for those tutorials to work. Now that they have been installed the tutorial 2.2 is working just fine. Thanks again and i'm sorry for the late reply.

[Kendawgg22]

Well I thought I was getting somewhere but I got stuck again. I couldn't get it to run the simulation using potentialFoam. So I upgraded to OpenFOAM 2012 hoping that would help but now it won't even generate the blockMesh.
I have images attached.
