wrong token type - expected word, found on line 80 the punctuation token '('

hasha · May 17, 2019, 12:01

Hello,
I am trying to create 2 blocks in a wedge of 5 deg, wedge radius of 7 mm and width of 5 mm. I have written my blockMeshDict when i am running this in openFoam 6 i am getting an error like this

wrong token type - expected word, found on line 80 the punctuation token '(' .

I have attached my blockMeshDict zip file, please help me i got stuck with this from a week.
I have 2 questions to you guys
1. Do the trailing spaces in blockMeshDict file causes any problem?
2. How should i define a interface boundary condition in case of multiple blocks?

Thanks a lot.

Just a hint

Ensure to leave an empty space before every $-sign in order to avoid the combination of signs to be interpreted as whole. For instance:

*$ - > * $
/$ -> / $
+$ -> + $
-$ -> - $
($ -> ( $

Except for:
"$ .... this should be fine.

Hello guin,
Thanks for writing back, I have done the same as you said but the error was same. please find the modified blockMeshDict and error reported.
The error it was showing at line 80 but i dont find any extra parenthesis there(highlighted line 80) . could you please help me out.

The error is due to a a missing semicolon at line 74 right at the end of "faces"-list, from "front" patch.
Nevertheless, you will get further errors. Take a look at the order of the points for the generation of the hex-blocks https://cfd.direct/openfoam/user-guide/v6-blockMesh/
Best,

I have checked the blocks the numbering is righthanded every where in the block i even changed it to another style but the error wont change. some body help me

, is it a bug why it is showing a wrong token type - expected word, found on line 71 the punctuation token '(' .
