I wrote the blockMeshDict and want to create now a blockMesh. During the process I get an error message. It says:

"In function void Foam::codeStream_efa88c99f17594f6f3c82927a0fb16235 e07ee90(Foam::Ostream&, const Foam::dictionary&):

What I understand, is that "d_sl_y" is missing, but it is part of my blockMeshDict, as you can see in my code

Code:
//Surface_layer
//
d_sl_x $d_s3_x; // horizontal size of surface layer
d_sl_z $d_p1_l; // length of surface layer (z)
d_sl_y 1.5; // vertical size of surface layer
Is there any explanation, why I get this error?
Thank you for your help

Thank you for your help
Since i don't know your blockMeshDict, your are a hundred percent sure that you are calling the variable efter defining it? Also, if you highlight the variable it should highlight everywhere else it is used in the script. This is just an easy way to ensure the format is the same in the file, i.e. that openfoam recognizes it as the same variable in the entire file.

If this is not the case, can you upload your blockMeshDict? A search on the "was not declared in this scope" error can be due to an error in the openfoam build. I guess this can be ruled out if I am able to run blockMesh without errors.

I tried it in a new mesh, and get again an error about a missing scope. I checked it and can not figure out, why its not working. For me it looks fine, i could not find a missing $ or something similar.


Is there any other reason, why this error message could appear?
Thank you a lot!

Hi,

Your problem comes from this line:
Code:
d_ss_x 1; erweiterte Breite
You forgot to comment out the text after ;

So it should be:
Code:
d_ss_x 1; //erweiterte Breite
And it does not give you the $coo_p_x not defined error.

However, I think you still have other missing/incorrectly named variables that you have called while defining your vertices. Check that.

Hope this helps.

Cheers,
Antimony
