Hi everyone,


I'm trying to implement at the Inlet a turbulent flow using ''turbulentDFSEMInlet'' along with text file for the velocity(points, U). The text file ''points'' is located in the directory /constant/boundaryData/inlet/points and the velocity file ''U'' in the directory /constant/boundaryData/inlet/0/U. You can see both files in attachment.


The file ''U'' located in the directory /0/U has the following string for the Inlet:


Inlet
{
type turbulentDFSEMInlet;
delta 0.075;
value uniform (0 0 0);
R uniform (3.5 -3.00E-01 2.07E-02 1.24E-01 3.4E-04 0.7);
L uniform 0;
nCellPerEddy 3;
mapMethod nearestCell;
}




Unfortunately, I got an error message as follow:


--> FOAM FATAL IO ERROR:
error in IOstream "" for operation Foam::Istream& Foam:: operator>>(Foam::Istream&, Foam::List<T>&) [with T = Foam::Vector<double>]

file: at line 1.

From function void Foam::IOstream::fatalCheck(const char*) const
in file db/IOstreams/IOstreams/IOstream.C at line 69.

FOAM exiting



Is anybody here has a clue what could be the issue and how I could troubleshoot / fix this? I thought that could be a memory issue, text files format or digit precision?


Thank you very much for your help!


Best Regards,

I finally found the issue.

The structure of the text files ''points'' and ''U'' was fine.

My only mistake was that the folder ''inlet'' was not matching the exact patch name ''Inlet''. The letter ''I'' in the folder name wasn't in cap.

Everything work fine now!

Thank for reading!

Hi Thibault,

I am facing the following error:

From function Foam::Istream& Foam:perator>>(Foam::Istream&, Foam::doubleScalar&)
in file lnInclude/Scalar.C at line 101.

While starting the run, I found the above error. I fixed each files as you have structured.

Please help me.

Thank You
