Hi all,

I am trying to read a csv file into the velocity boundary conditions (FOAM_CASE/0/U), and below is what I did.

    mainJet
    {
      type            timeVaryingMappedFixedValue;
      offset          csvFile;  
      csvFileCoeffs
      {
            nHeaderLine         0;
            refColumn           0;  
            componentColumns    (1 2 3); 
            separator           ",";
            mergeSeparators     no; 
            fileName            "myDataFile"; 
            outOfBounds         clamp; 
            interpolationScheme linear; 
       };
       setAverage      off;
    }

I have attached the csv file that I intend to read.
Can some one tell me what is the problem with my csv file and csvFileCoeffs settings?

Everytime when I try to run the case I get the following error message from OpenFOAM:

--> FOAM FATAL IO ERROR: 
Cannot open CSV file for reading.

file: myDataFile at line 1.

    From function CSV<Type>::read()
    in file lnInclude/CSV.C at line 82.

FOAM exiting

Thanks in advance!
Longfei

Hi,
You should give the path of the file where you didn't mention it.

it should be like this

fileName "$FOAM_CASE/mydataFile";


and you should place your file in the case folder.
