OpenFoam blockMesh error
 

Hello to all the member of Frum,

I am a new user of CFD code OpenFoam
I installed the 2.3.0 CFD code OpenFoam there some time but it does not work well. Because for the tutorial cavity when I run the "blockMesh" command on the terminal
in the $ FOAM_RUN / tutorials / incompressible / icoFoam / cavity directory,
I get the following errors in the terminal:
///////////////////////////////////////////////////////

Create time

NB: the result of the command "cat log.foamInstallationTest" on the terminal is:

Please I need your help to solve the problem I do not know the origin.

Hello and welcome to the forum,

It seems like your installation for OpenFoam is correct. You have also tipped 'of230' in the terminal before you started?

And I could help you more if you upload a *.log - file From which folder are you running your program?

Hi,

it seems you're trying to run blockMesh in cavity/constant/polyMesh folder while you should run it in just cavity folder.

Hi alexeym.
thank you for your help.
you're right I was poorly executed the commamde "blockMesh"
the prblome is resolved.
thanks

Hi jokerito.
the problem is solved.

i execcted "blockMesh command " in case directory

thanks you

Hey,

I'm a barely new user too.

Could you tell me, please how can I run only in the cavity folder?

(if I run the blockMesh commend in the case directory -cavity-, I get the same error msg)

Thanks

blockMesh error
 

Hello all,
I am new at Openfoam and I have question about blockMesh. When I run blockMesh command on the cavity file, the system gives me this error:

FOAM FATAL ERROR:
cannot find file "/opt/openfoam5/tutorials/incompressible/icoFoam/cavity/system/controlDict"

From function virtual Foam::autoPtr<Foam::ISstream> Foam::fileOperations::uncollatedFileOperation::rea dStream(Foam::regIOobject&, const Foam::fileName&, const Foam::word&, bool) const
in file global/fileOperations/uncollatedFileOperation/uncollatedFileOperation.C at line 505.

FOAM exiting



Do you know how can I solve this problem?
Thanks,
P.

You need a controlDict file in your system dictionary:

"FOAM FATAL ERROR:
cannot find file "/opt/openfoam5/tutorials/incompressible/icoFoam/cavity/system/controlDict"

If you are totally new to OF, you should go through this user guide:
https://cfd.direct/openfoam/user-guide/
After this a lot of stuff will be clear.
