Hello,
I have foam-extend 4.1 and openfoam v1906 installed on Ubuntu1804 (Windows subsystem). I'm also using aliases to switch between both environments.
the ESI version works without any problem, but when I try to use anything in foam-extend, for example "blockMesh -help", I get the following error:

--> FOAM FATAL ERROR:
           Could not find mandatory etc entry (mode=ugo)
           'controlDict'

same thing when I try "simpleFoam -help"
I saw in a previous post by Wyldckat that this might happen when OF is installed in a directory containing spaces, but it is not the case. the command which foamExec gives:

/opt/foam/foam-extend-4.1/bin/foamExec

the "tut" command goes correctly to foam-extend tutorials folder, so the environment seems to be correctly loaded.
Thanks in advance for your help,

Kazu

No one?
Is this Me? Covid-19? or the participation rate in the forum has been falling lately???

I have same kind of problem. You foam-extend doesn't look that it was installed fully.
How was your installation process like? In my system, the installation wouldn't budge.

It may be because the extend version didn't run from source.
you can make another version into comment like below

$vi ~/.bashrc
(at almost last line)
# source /opt/OpenFOAM/OpenFOAM-v1912/etc/bashrc

and then
$fe40

then run the case by extend version.

And, I want to ask you, did you install 4.1 without any problem?
Because I am trying to install extend 4.1 in ubuntu 18.04 LTS (WSL) but still having trouble.

Hey Gozo,

I installed version 4.1 without any obvious error or warning. Did you try doin an apt-get -update Before installing? The problem is the environment. I will try again with 4.0...

Hi, Stephane.
I'm using the extend-4.1 version now, too. My installation error was resolved after installing the WSL2.
And it does not look that every solver works, but I have been figuring out.

Hello, I am trying to use foam extend 4.0. Can anyone please tell me if there is anyway to use OpenFOAM mesh on foam extent? because apparently the both use different mesh files. i cannot find any code to convert meshes. If anyone can help me in this regard?
