Hello everyone,

I am faced with an error I couldn't solve. I am trying to feed a csv file into my temperature boundary condition to obtain a time and space varying temperature field. The problem is that I get an error like the following although the file is not empty:

--> FOAM FATAL IO ERROR: 
Table read from "Heat_fluxes_nadir1.csv" is empty


file: Heat_fluxes_nadir1.csv at line 2.

The BC for one of the patches in my T file is as follows:

    plusX
    {
    type         uniformFixedValue;
    uniformValue
    {
        type             tableFile;
        format           csv;
        nHeaderLine      0;              // number of header lines
        refColumn        1;              // time column index
        componentColumns (2);            // data column index
        mergeSeparators  yes;             // merge multiple separators
        file             "Heat_fluxes_nadir1.csv";
    }
    }

What could the error be? Why do you think it reads my file as "empty".

Can't say at all, without knowing what your case setup is and what your file contents are. (A minimal test case). This probably why nobody has answered.

I just changed the separator from dot to comma and it worked.

Dear Utkan,

I have a question abot using csv files in openfoam and I would be thankful if you help me.
I am doing some experimental research and I have the velocity vector in a domain in a csv file. I would like ti read this file in the paraview in order to postprocess it. As far as I know, after importing the file, I need to use "table to point" filter. I did it successfully. Now, I would like to plot velocity over a line, but it does not work. I think there are some missing seteps in between in order to be able to post process further. I would be thankful if you share your opinion with me.

Best regards
