Hi Guys,

I've just installed OpenFoam on windows 10, and I was about to try my first example from tutorial. However, before I do it, when I typed "blockMesh" for the very first time I got this error. Can anyone help me out?





To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

If you execute `blockMesh` in the middle of nowhere, you would get this message.
`blockMesh` requires to be executed inside a computation directory wherein `system` and `constant` directories, and the main dictionaries must be present.

As a relatively inexperienced Linux user, I don't know the difference between "middle of nowhere" and "inside a computation directory".

I have reinstalled OpenFOAM from scratch for the umpteeth time using wsl on Windows 10. In the process I have moved some files contained in C:\Users\sauce\Downloads and C:\Users\sauce\Documents from C: to D: due to running out of space on C:.
I do not know if that's the reason I now get an error when trying to run simpleFoam from the PowerShell after installation.

I've been importing geometry, creating meshes and viewing in ParaView the model on the Windows installation of Salome.

simpleFoam was working fine a few days ago:

FOAM FATAL ERROR: (openfoam-2312 patch=240220)
cannot find file "/home/system/controlDict"

Any suggestions are very much appreciated.

When starting a new terminal session in linux you usually log in your home directory. You can then navigate into directories using the cd command.

Most of OpenFOAM commands needs to be run from a case directory containing a system directory with a controlDict file + other files depending on the command you want to use.

OpenFOAM is telling you it cannot find a controlDict file in /home/system.
You are most likely trying to execute simpleFoam from /home/ instead of from a case directory.

You need to use the cd command to move to your case directory before running simpleFoam.

Cheers,
