Greetings Sergeyevichsky,

I don't know if you have solved this problem or not, but it should be because Open-MPI was not properly picked up by OpenFOAM's environment loading scripts. If you follow the instructions given here: https://openfoamwiki.net/index.php/I...u#Ubuntu_14.04 - it should be possible to build OpenFOAM 3.0.x on Ubuntu 14.04.

The main details that might be missing from your installation:

• Ubuntu's Open-MPI packages should be installed, possibly with the following command:
  

  sudo apt-get install libopenmpi-dev openmpi-bin

• Step #6 on the wiki page, section "Ubuntu 14.04", has the commands needed for enforcing that the correct MPI installation is found by OpenFOAM's scripts.

Best regards,
Bruno

Hi Bruno
Thanks for your help, I have solved this problem by installing Ubuntu 16.04.2, but I'm still very grateful to your help.
