Hello,
I'm running some simulations for my thesis with openfoam. I started with the motorbike file (simpleFoam simulation) and I changed geometry with mine. There are two different geometry files.
I didn't find any problem with the snappyHexMesh command but now I'm trying to run the simulation and I have this error message:

I checked every file and I didn't find anything wrong for what i know. Where should I check?


Hope someone can help me! Thank you!

Hello,

Your error seems to be related to the function objects used in controlDict, and more specifically the patches parameter of the function near:

[4] Wrong token type - expected word or string, found on line 0: punctuation '{'
[4]
[4] file: stream.functions.near.patches at line 0.

If you have updated this parameter, make sure there is no syntax issue with it.

Regards,
Yann

Thank you for your reply!
I think I found the mistake in system/wallBoundedStreamLines, where I define the near function. I wrote:


near
{
type nearWallFields;
libs (fieldFunctionObjects);

writeControl writeTime;

executeControl writeTime;

fields
(
(U UNear)
);

patches
(
{
name wheelGroup;
}

{
name alaanterioreGroup;
}
);

distance 0.001;
}


The problem should be with the brackets in patches, am I right? But what's the correct way to write it?

[Yann]

This is it indeed, this is not the proper way to write it, you just need to give a list of patches or groups:

patches (wheelGroup alaanterioreGroup);

You can have a look at the documentation for more details: https://doc.openfoam.com/2306/tools/...earWallFields/

Cheers,
Yann
