Hi,
I'm using a new installation of OpenFOAM (Foundation) version 11 on Ubuntu 22.04: the latest release.
Got the following error trying to run blockMesh for a copy of tutorial 2.1: Backwards-Facing Step.

As you can see the blockMeshDict file is where it should be with okay permissions.
Here is my directory listing and path:
~/OpenFOAM/john-11/run/back_step_tut/pitzDailySteady

total 24
drwxr-xr-x 2 john john 4096 Oct 14 18:12 ./

I should have adequate permissions for executing blockMesh. Is it a compiler error? I did not compile my OF from source but installed a pre-compiled version which seemed to install sucessfully.

Any help would be appreciated.

You tried to run blockMesh from the system directory. You have to be at the root of your case to run commands.

Cheers,
