Hi every one,
I copied one interFoam file and then edited it. When I was trying to make blockMesh file I faced a problem that says:
"
--> FOAM FATAL ERROR:
Cannot open mesh description file
"/home/dell-2014-d/Learning/ellipsoidal/constant/polyMesh/blockMeshDict"


From function blockMesh
in file blockMeshApp.C at line 137.

FOAM exiting
"
Can you help me what the problem is? Since I am beginner in OpenFoam, any help will be useful.
Best regards

Hello javadrasooli,

the problem is, that there is no blockMeshDict file in the polyMesh folder. Have you checked it?
I am not sure, but I think you have to work in the run folder of your OpenFoam installation.

Best regards,
Mike

Hi Mike,

Thank you for your response. As I wrote, I copied the file so there is a "blockMeshDict" file in polyMesh folder, but I did not put it in to run folder. Is that also for Ubuntu 14.04 and OpenFoam 2.3.0? How should I put it on run folder.

Best regards
Javad

Hello javad,

I tried to reproduce your error and when my working directory is in the run directory and I had no blockMeshDict file in the polyMesh folder, the same error 137 occured. But when I execute the program with a copy for example in my documents directory another error ocurred (can't find file... line 73...)

So my suggestion would be, to copy the program in the run directory, which is in my case: /home/mike/OpenFOAM/mike-2.3.0/run/
You have to look where your OF installation is installed. Btw I am also working with Ubuntu 14.04 and OF 2.3.0

From the terminal you have access to the run directory after the of230 command just with run and then you switch to your test case.

Ah, have you made the last step Getting started http://www.openfoam.org/download/source.php during the installation? There it is said to make the run folder...

Hope it works.

Mike

Dear Mike,
Thank you so much for your attention.
I've put it into run folder and the problem is the same!!

Hello,

Hmm... Strange, could you upload your BlockMeshDict file, so I could try to reproduce the error and can try to fix it?

I have been having the same issue although I am on Ubuntu 13.10 Saucy. It is as though the file is overlooked. I am running Ubuntu live as well...

Greetings to all!

Knowing that you're running a Ubuntu live installation does make it a bit easier to isolate the problem. I've quickly tried out using a live Ubuntu 13.10 in a VM with only 2GB of RAM and was not able to install OpenFOAM 2.3.0 from Deb packages, because it ran out of RAM for the virtual on-memory disk.
Soooo... my question is: are you perhaps using a live USB installation?

In addition, knowing the exact commands/steps you've used to make the copy would help isolate the problem.

Last but not least, try running the following commands and let us know what it outputs:

ls -l .
ls -l constant
ls -l constant/polyMesh

----------------

edit: I've tried with a live Ubuntu 13.10 with persistent capabilities, similar to a USB mechanism, and I was not able to reproduce the same error.
A few additional commands to help diagnose the problem:

df -h ./
pwd

Best regards,
Bruno

[CHagen]

It is a USB live and its on a 4GB.

I have been moving so I will try to get to the rest of what you asked as soon as I can. Just wanted to touch base and let you know Im working on it.

I appreciate the help

I think u need to add in the preamble
location "folderName";

Hai,
I am a new user as well and I am having the same problem.

Please let me know how to rectify it.

I followed this tutorial:

[Antimony]

Hi,

You have done a

ls -l

of

constant/Polymesh

instead of

constant/polyMesh

. The case matters a great deal.

Cheers,
Antimony

[tanveerfathima]

Anitimony, I have corrected. Still getting the same result.

[wyldckat]

Quick answer @tanveerfathima: OK, the tutorial case you are using has the "blockMeshDict" file located in the folder "system". That means that you will either have to move the file from "system" to "constant/poyMesh", or run it like this:

blockMesh -dict system/blockMeshDict

Why are you using OpenFOAM 2.3.0? The tutorial case that you are using, at least the latest version, was designed to work with OpenFOAM-v1812 and OpenFOAM 6.

[tanveerfathima]

Thanks a lot @wyldckat . I installed OpenFOAM 6 and it worked!
