Hello all,
I have a question about one of jet flow simulation in OpenFoam.
I try to run the Jet flow work but when I run the code, I get an error. please Can you help me?
Thank you so much
The error: (I remark the line 56 in the error)

--> FOAM FATAL IO ERROR:

Hi,

The error message informs you there is an issue with scalarTransport function which is included just before line 56:

#includeFunc scalarTransport

It also tells you what you should do:

The function entry should be:
scalarTransport(field = <fieldName>)

If you did not intend to use this function in the first place, just remove it from your controlDict.

Also, please be careful to give a proper title when you create a new thread. (How to give enough info to get help)

Regards,
Yann
