Dear all,
I am facing problem while going through the tutorials. i am new user of OpenFoam. in cylinder case when i put Allrun command to run the problem i am getting following error in paraFoam window.

& when i am adding command of blockMesh i am getting following error message
--> FOAM FATAL IO ERROR:
This code should not be executed by someone with administrator rights due to security reasons.
(it writes a shared library which then gets loaded using dlopen)

FOAM exiting





Please help me out to understand what is the problem

[nimasam]

well;

could not find valid OpenFOAM mesh

means there is no mesh created

& when i am adding command of blockMesh i am getting following error message
--> FOAM FATAL IO ERROR:
This code should not be executed by someone with administrator rights due to security reasons.
(it writes a shared library which then gets loaded using dlopen)

file: /root/OpenFOAM/tutorials/basic/potentialFoam/cylinder/constant/polyMesh/blockMeshDict from line 17 to line 17.

FOAM exiting

this tutorials uses a dynamic code (codeStream), means a part of blockMesh will be compiled and created in runTime, so to use code stream you should enable allow System Operations. read this thread.

[monty86]

Dear Nima,
As per your suggestion i activate the allow system operation by replacing 0 with 1 but still getting the same error. am i missing something in this or have to replace with other number?

[alexeym]

Hi,

the error is self-explanatory

--> FOAM FATAL IO ERROR: 
This code should not be executed by someone with administrator rights due to security reasons.
(it writes a shared library which then gets loaded using dlopen)

file: /root/OpenFOAM/tutorials/basic/potentialFoam/cylinder/constant/polyMesh/blockMeshDict from line 17 to line 17.

And it says that you should not run simulation using root account. Make OpenFOAM accessible to users and run the case from user account.

[monty86]

Dear alexey,
Now i got it, I installed OpenFoam as a sole root login. without root login i am not able to run any case. Is there any way how i can add another user account & run OpenFoam without root login? I dont want to do again Open foam installation procedure. This may be silly question but i am stuck on it.

[alexeym]

Hi,

as I don't know what Linux distribution you're using, my hits will be rather generic. In general it's simpler to install OpenFOAM system-wide using package manager (this way all permissions will be set correct and OF will be usable by all users of the system) but since you've decided to build it, here is the way to transfer it from root account to use account (by convention # will be shell prompt of root account, $ will be shell prompt of user):

1. Create ordinary user

# useradd -m ofuser
# passwd ofuser

these two commands will create ordinary user account and set its password. -m switch will instruct useradd utility to create home folder, usually it is /home/ofuser.

2. Copy (or move, in this case use mv instead of cp -r) OpenFOAM folder from root home to new user home

# cp -r /root/OpenFOAM /home/ofuser/

3. Fix ownership of the installation

# cd /home/ofuser
# chown -R ofuser OpenFOAM

Now you can login as ofuser and try running tutorials

$ cd
$ source OpenFOAM/etc/bashrc
$ tut
$ cd basic/potentialFoam/cylinder
$ ./Allrun

Though your way of naming OpenFOAM folder seems rather strange to me, as usually it is installed into $HOME/OpenFOAM/OpenFOAM-<OF version>.

Hello Alexym,
I have the same error as mentioned above

FOAM FATAL IO ERROR:
This code should not be executed by someone with administrator rights due to security reasons.
(it writes a shared library which then gets loaded using dlopen)

I am using openFOam on windows, I made the programme accessible to guest and tried using the blockMesh command in the guest account for the cylinder case but I get the same error. Kindly Help.

[Artur.Ant]

Hello
I also had this problem installing openFoam on Windows.
I solved it doing these steps:
1)go to ... src/OpenFOAM/db/dynamicLibrary/dynamiCode folder
2)open dynamicCode.C file
3)comment the part of the error like this:

/* if (isAdministrator())
{
FatalIOErrorInFunction(dict)
<< "This code should not be executed by someone with administrator"
<< " rights due to security reasons." << nl
<< "(it writes a shared library which then gets loaded "
<< "using dlopen)"
<< exit(FatalIOError);
}
*/

4)go back to ...src/OpenFOAM folder
5)compile openFOAM with command:
wclean libso && wmake libso 2>&1 | tee log.wmake
6)if you don't have 'make' install it
for more information visit this link: https://www.computerhope.com/unix/umake.htm
7)if you don't have 'zlib1g-dev' library install it.
Hope this will help someone.
Artur

I just wanted to let you know that this just saved my life, thank you so much!
This worked for me in a RHEL centOS 7.6 system, using the v6 openfoam image for docker.

Dear alexeym,

I wanted to do what you mentioned, but I faced with these problems:

1- When I wanted to create a new user, it gave me "permission denied" error! So, I log in with admin using "sudo -s". (Did I do right? or I didn't have to log in with admin?)

2- I did not have "OpenFOAM" folder as you did, so I copied openFOAM-7 folder. (Did I do right? or I had to find the same folder?)

3- The openFoam folder is copied in /opt/home/ofuser address, not in main home! What did I have to go?

4- Again, the "# chown -R ofuser OpenFOAM" command did not work, as I have no OenFOAM.

At last, I couldn't use the openFoam on my home folder!

Regards,
Ali

For anyone running docker containers with automated applications we skip the whole user permissions, meaning you have permissions to do all of this if you have permissions to run the app. It make4s everything clearer. So is there a way to do the dynamic calculation without having to create a user?

Followed your steps but stuck at 5th step. How do I compile in OpenFOAM folder?
Thanks

please help why this error is persists

I am using openFOam on windows, I made the programme accessible to guest and tried using the blockMesh command in the guest account for the cylinder case but I get the same error. Kindly Help.

Right-clicking on the main OpenFOAM folder, going to properties, changing the security settings and allowing full control to all users should work as it did for me

[ghastbug]

Khan,
As far as I understand, you have to run the make files in OpenFOAM\v2106\msys64\home\ofuser\OpenFOAM\OpenFOA M-v2106\src\OpenFOAM. So first you tell shell to go there (you use cd), and then you input the command (wclean libso && wmake libso 2>&1 | tee log.wmake).


I did that, and I got this error though:

alessandro.sarti@28APO4951 MSYS ~/OpenFOAM/OpenFOAM-v2106/src/OpenFOAM
$ wclean libso && wmake libso 2>&1 | tee log.wmake

Looks like openFOAM's wmake folder does not have rules for win64Mingw. Sooo, maybe we have to switch to Linux.

Actually, I don't even know C, but it looks like shell first opens rules/General/general, and then, it sees there that it has to switch to win64mingw/general, which does not exist. So maybe there is a way to edit general/general so it doesn't refer to the win64mingw rules that don't exist, or we can make a rule file in win64mingw

Hey!
I am just starting out with openfoam (on windows) and I have the same issue. I wanted to edited the dynamicCode.C like mentioned above, but when I search for the directory "dynamicCode" I just find a folder under etc/codeTemplates and it doesnt have a dynamicCode.C file.

Running the blockMesh command throws the admin error, and also says -->
From static void Foam::dynamicCode::checkSecurity(const char*, const Foam::dictionary&)
in file db/dynamicLibrary/dynamicCode/dynamicCode.C at line 72.
<--

Based on this it seems the file dynamicCode.C should be found when searching the folders but no...

I tried a cd $FOAM_SRC command but it also just says No such file or directory.

Help a lost soul out pls.

i have the exact same problem. Is this due to a newer version of OpenFOAM?

[CMP23]

Hello,
I had the same issue is referred here:
"--> FOAM FATAL IO ERROR: (openfoam-2306)
This code should not be executed by someone with administrator rights for security reasons.
It generates a shared library which is loaded using dlopen."
I'm using OpenFoam 2306 with ubuntu WSL. I tried coment some of the code like is sugested on this forum, however, then i wasn't able to use the libraries due to :"error while loading shared libraries: libOpenFOAM.so: cannot open shared object file: No such file or directory" erro.
I have also tried to implement a new user like its suggested, however the command "chown -R ofuser OpenFOAM" shown the follow error message:"chown: cannot access 'OpenFOAM': No such file or directory".

Can you give me some tips.
Best regards.
