Goodmorning,
i'm new to the forum and also to using OpenFOAM.

It's been three days that i'm trying to import a csv file as inlet boundary condition for my simulation.

I think to use the right code string, but i don't understand where can be the error.

The following is the code string:

inlet

{
type uniformFixedValue;
uniformValue

{
type csvFile;
nHeaderLine 0;
refColumn 0;
componentColumns (1);
separator ",";
mergeSeparators no;
file "inlet.csv";
{


}

And the following is the error when i try to run the analysis:

--> FOAM FATAL ERROR:
Unknown Function1 type csvFile for Function1 uniformValue

Valid Function1 types are:

17
(
coded
constant
halfCosineRamp
linearRamp
one
polynomial
quadraticRamp
quarterCosineRamp
quarterSineRamp
reverseRamp
scale
sine
square
table
tableFile
uniform
zero
)



From function static Foam::autoPtr<Foam::Function1<Type> > Foam::Function1<Type>::New(const Foam::word&, const Foam::dictionary&) [with Type = double]
in file /home/ubuntu/OpenFOAM/OpenFOAM-8/src/OpenFOAM/lnInclude/Function1New.C at line 48.

FOAM exiting

If someone has some solution he'll be gratefull.
Thank you, and sorry if someone in the forum has already posted the same question, but i didn't find it.

Hi - you need to provide a bit more information on your problem and case. A good start would be your 0 folder files and some idea of the axial relationships in your geometry. Maybe a pic of your geometry - I assume you've meshed ok.

I solved it. Thank you. It was a problem with the installed version of Openfoam.

Hi Aydan - the idea of sharing in the forums is that if you ask for help and then solve the problem - you share that solution with others so they don't have to suffer the same torture - it's the community thing. Thanks, Regards

Here is a working example of how to read velocity of a boundary condition from csv file:

 inlet    

{
        type       fixedProfile;
        profile    tableFile;

        profileCoeffs
        {
            format              csv;        // Input format
            nHeaderLine         1;          // Number of header lines
            refColumn           11;          // Reference column index
            componentColumns    (0 1 2);        // Component column indices
            separator           ",";        // Optional (defaults to ",")
            mergeSeparators     yes;        // Merge multiple separators
            outOfBounds         clamp;      // Optional out-of-bounds handling
            file                "input/U_k_epsilon.csv";
            interpolationScheme linear;     // Optional interpolation scheme
        }
        direction        (0 1 0);
        origin           0;
  }
