Im triying to construct a cylindrical geometry with inflow in top and outflow in the bottom section. I read about axial symmetry but I was triying to construct in the simpler way possible to start.
The error console gives is:

In my actual knowledge the error is totally obscure for me.

Greetings Francisco and welcome to the forum!

Please use the "[CODE]" markers for isolating source code... in advanced editing mode, it's the "#" button ;)

Now, the error tells you that the problem starts at "boundary", so let's look at what "boundary" defines:
Notice the sudden drop in the list between "pared" and "salida"?
It should be something like this (in bold are the lines that were added):
If you don't want to keep designing meshes for blockMesh using text only, try SwiftBlock: http://openfoamwiki.net/index.php/Contrib/SwiftBlock

Thanks for the answer, after your response I continue work in the file but still getting errors, I was capable of catching a couple ( ,'s in vertices definition, bad definition of arcs). Following recomendation of another post I try to construct the geometry by parts to isolate the error. Succesfully construct the inferior part, now when I try to add the intermediate part I obtain an error I im incapable of repair. Please help.

Hi Franscisco,

I can't test your file right now. But in the meantime, I forgot to mention a feature that can assist you in debugging the "blockMeshDict" file - run paraFoam like this:
It will show you how conceptually the mesh will look like.

Best regards,
Bruno

:D thanks again for the answer, with the command you indicated I was capable of debugg the error, almost all the errors reported were in the end caused for creting combinations of blocks and faces that can cause and element of the discretization could end being in two boundary conditions.
Based on geometry of another thread I divided my domain in more blocks to allow each of the faces being the complete side of one block.
More code but now I undertand more the logic of the program.
Thanks again for the time dedicated to answer me. :D

ill defined primitiveEntry at boundary
 

Hello guys,

Sorry to keep on this error but I am trying to run a blockMeshDict file for a cylindrical domain with multiple inlet faces.

However when I run blockMesh on this file I get the same ill defined primitiveEntry at boundary error,
After reviewing this thread it seems to me that this is because of any syntax errors in the boundary condition definitions of the dict file. But after going through the blockMeshDict, I cannot for the life of me figure out any syntax errors that I have made.
Can I please get some help with this error? May be a second eye.:confused:
Thanks in advance!

Regards,
Dhaval

Hey guys,

Got it. :D There is one extra parenthesis in the hotPlate/faces section.
Please don't waste your time to reply to the previous thread.

Thanks a lot!

Dhaval

Hi every one!
I have a similar problem too. I have checked all my blockMeshdict file but no result:(

but I face this error:

can any one please please tell me what to do?
thanks!

it usually happens when the file misses ) or } or ] or ;
check them :)

Dear Dr. Samkhaniani,
Thanks a lot for you kind reply. I have checked my file several times but no result:(
I have attached my blockMesh file. Would you please please take a look at it?
thanks again and again and best regards.

add the whole case file here

Check that all your boundary definitions have spaces between the scalar or vector values...I have had that problem before.

i have same problem,can anyone help me?

Please note that that the shape I am creating is a square cylinder within a rectangular wind tunnel. I have sliced it in half along the x axis as it is symmetric so i am only modeling the upper half.

Hi,

I think your problem is related to this:

You cannot have whitespaces in a patch name.
