Hi

I simulated a case without problem in a computer, in which only Ubuntu 1804 was installed. But if I copy the case files to a windows 10 computer and simulate the same thing, there is always this error message... I installed the Ubuntu in Windows 10 in this way "https://www.openfoam.com/download/install-windows-10.php". How can I solve this problem?

Could you post your controlDict file?

Thank you for your answer, I post the controlDict.

Your controlDict is OK. But I think the problem is somewhere else with other files.
  • * Which version of OpenFOAM you used on Ubuntu 18.04?
    * Did you check that all the files on your case have a header?

Hello,


Another idea: it might be related to linux/windows line endings issues.


Have you edited your controlDict in windows? And if yes, with which software?


You can use vi right from the terminal to check if your controlDict file is ok, or use an editor such as Notepad++ on windows. (Open your file in notepad++, then "edit/EOL Conversion". It should be set to "Unix")

@Evren Linda: OpenFOAM version is v1906 and I checked that all the files have a header.

@Yann: Thank you for your idea, but with vi and notepad++ it doesnt work.

I can still see the same error messages like what I posted yesterday.

I just recognised that simpleFoam and icoFoam work well. Hymm, what can be the reason for this problem...? My solver is pimpleFoam.

I'm pretty sure I faced this error before but I can't remember what it was.


Could you elaborate about what you tried?


Have you tried to run icoFoam and simpleFoam on your case or on another case/tutorial?
Have you tried to run pimpleFoam on a tutorial?
When you run your case on your windows system, do you run it from scratch or restart the case from a previously saved time step?

@Yann

Thank you for your answer once more.

1.Have you tried to run icoFoam and simpleFoam on your case or on another case/tutorial? - I just started two tutorials with icoFoam and simpleFoam, not my case.

2. Have you tried to run pimpleFoam on a tutorial? - After that I read your answer, I started a simulation of tutorial channel395. The simulation for channel 395 works well with pimpleFoam!

3. When you run your case on your windows system, do you run it from scratch or restart the case from a previously saved time step? - I installed my ubuntu 18.04 LTS from

https://www.microsoft.com/de-de/p/ub...ot:overviewtab

... and I restarted the case from a previously saved time step (t=3.2 s) as I posted two days ago.

Then the error is most probably related to your case.



I suggest to narrow down the potential issues by restarting your case (or a copy) from scratch, as you did the first time on your other computer.

If you still get the error, try to simplify your case, for instance by deleting the functionObjects, until it works or until you can identify where does the error come from.

The problem is solved! I installed "make",

sudo apt-get install make

and it works well!

Hi,
I am using interFoam. However, I am using cray supercomputer to run my simulations. On spercomputer I have openfoam v 1712. On the other hand, I have openfoam 7 on my PC which uses Linux OS. After checking my code runs well on my PC I transferred my working directories to supercomputer. When I ran the simulations I got the same error:

Reading "/home/metprocmodlgrp/144110018/two_sphere_3/system/controlDict" at line 1
First token could not be read or is not the keyword 'FoamFile'
P.S. I replaced the version of all the file header from 7 to v1712. Still the same error is appearing. Can anyone help me on this?
