Hi everyone,

I'm facing an error while running simulations that include a function, whether it's used in controlDict or as an fvOptions. I have compiled OpenFOAM 8 using the source code, and everything else is working perfectly. However, I am facing this issue specifically when trying to utilize a function, which results in the following error:

 
--> FOAM FATAL IO ERROR:
error in IOstream "OSHA1stream.sinkFile_" for operation Ostream& operator<<(Ostream&, const word&)

file: OSHA1stream.sinkFile_ at line 0.

    From function virtual bool Foam::IOstream::check(const char*) const
    in file db/IOstreams/IOstreams/IOstream.C at line 96.

FOAM exiting

OF compiles without errors, and removing the functions simulates the same case without issues. I would appreciate your help with this.

Thank you in advance.
Hamed
