hello everyone,
I have just installed OpenFOAM on my laptor running UBUNTU 20.04, I have tried to run a tutorial as a test, to see if everything is working but once I selected the ShockTube folder that I have previously copied on my desktop, I tried to generate a mesh using the command 'blockMesh' but it returns the following error:

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

I have checked and the controlDict file is in the right folder "system".
Does someone have a solution?

Thank you.

Hi Alessio,

make sure that the file header of controlDict is properly set up like this:

FoamFile {
   version  2.0;
    format  ascii;
     class  dictionary;
    object  controlDict;
  location  "system";
 }

A wrong class may make OpenFOAM give an error message that the file is not found, although it may very well exist and has the correct file name. The correct filename alone isn't sufficient. The file header needs to be correct too. Hope this helps.

Do other tutorial cases work properly?

Hi, Probably something wrong with your .bashrc file.
source home/username/OpenFOAM/OpenFOAM-v2012/etc/bashrc.
