Hi,

I recently installed Ubuntu 16.04 and OpenFoam 3.0.1 Helix-OS v2.3.1.
When I try to create the mesh with HelyxOS, I get an error: "blockMesh command not found".

I had a look at previous threads and tried everything, but without success.

The OpenFoam installation tutorial I followed suggested to create an alias called "ofdev" in the personal .bashrc file, so I did it.

The command blockMesh runs in the terminal, but only if I first call the alias "ofdev".
However, when Helyx tries to create a mesh, it opens a new terminal and the same error reappears.

I tried to fix the issue as following. I ran the command

sudo gedit .bashrc

and I added the line:

source /home/pietro/OpenFOAM/OpenFOAM-dev/etc/bashrc

but this didn't help.
I tried to paste this line to the HelyxOS script for generating the mesh, but did not help.


Any idea???

Hi pft,

Have you sourced your ~/.bashrc after linking it to your /home/pietro/OpenFOAM/OpenFOAM-dev/etc/bashrc? If not, get to the point you were at before, then do this in your terminal.

source ~/.bashrc

Also, it's not necessary to edit your bashrc file as root (sudo) because it's in your personal user directory (~ = $HOME = /home/pietro/ are all synonyms by the way).

Hi edbarino, thank you for the reply. I tried as you said, but with no luck.
If I navigate with the terminal to the analysis folder, then call the alias "ofdev" and run blockMesh, the command runs.

I believe Helyx-OS opens a new terminal when running the mesh script, and the new terminal does not call the alias "ofdev" nor the "source ~/.bashrc"
I am new to ubuntu, but this is my best guess.

I am facing the same issue.

I tried your suggestion without any luck. Could you elaborate on that?
I also tried what is suggested here, which doesn't work either.

Any further suggestions?

One of the nice things about HELYX-OS is that you do not need to change your .bashrc to source any OpenFOAM installation for HELYX-OS to work. You simply need to have

1. A compatible version of OpenFOAM i.e. HELYX-OS 2.3.1 will use OpenFOAM 2.4.0. if you are trying to use openFOAM-dev, then you will have issues since there is a change int he turbulenceProperties definition and several other small changes. Make sure you have a compiled version.
   
2. You will also need to have this version selected in the preferences inside HELYX-OS. You will just need to select the top level folder, meaning navigate to the OpenFOAM-2.4.0 folder only inside preferences.

This will then allow you to run meshing and solver applications in HELYX-OS.
