With OpenFOAM v8, when running a case, which works fine with OpenFOAM v7, it failed with an error message that uniformValue doesn't have type csvFile. Does anyone have the same issue? I attach the inlet boundary condition below.

 
 inlet  
  {  
      type         uniformFixedValue;  
      uniformValue  
      {  
          type             csvFile;  
          nHeaderLine      4;              // number of header lines  
          refColumn        0;                // time column index  
          componentColumns (1);     // data column index  
          separator        ",";               // optional (defaults to ",")  
          mergeSeparators  no;        // merge multiple separators  
          file             "dataTable.csv";  
     }  
  }

Hi,

Could you try to reproduce the issue with a standard tutorial? If it can be reproduced by others, would be nice to submit a bug ticket.

Thanks for your time.

Thanks Herpes,

Attached is a pitzDaily of pimpleFoam. I revised the inlet of U to include csvFile.

The model runs fine with OpenFOAM v7. When it is run with OpenFOAM v8, it failed with the following error message.

Please check and confirm. Note, in OpenFOAM v8 User Guide page U-150, csvFile is listed as an option.

Reading field U

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

Valid Function1 types are:

11
(
coded
constant
one
polynomial
scale
sine
square
table
tableFile
uniform
zero
)

The convention for specifying data from a csv changed, see e.g. the fixedProfile.H file (fixedProfile). You'll now use the tableFile option with format csv.

Thanks for your check, Caelan.

As you can see, I'm using csvFile for boundary condition type uniformFixedValue, which is different from fixedProfile. Both can read csv file but one is a profile over time and the other is a profile over space.

Is it a bug that Function1 uniformValue misses the type csvFile?

[clapointe]

The fixedProfile was just an example of how the code changed -- it is clear, I think, that tableFile has replaced csvFile in version 8.

Thanks Caelan. Yes, you are right and I made it work per your instruction.

In version 8, there is no csvFile type. Below is the script to use tableFile.

    inlet
    {
        type      uniformFixedValue;
        uniformValue   tableFile;
        uniformValueCoeffs
        {
            format              csv;
            nHeaderLine         0;          // number of header lines
            refColumn           0;          // reference column index
            componentColumns    (1 2 3);    // component column indices
            separator           ",";        // optional (defaults to ",")
            mergeSeparators     no;         // merge multiple separators
            file                "data/velocity.csv";  // name of csv data file
            outOfBounds         clamp;      // optional out-of-bounds handling
            interpolationScheme linear;     // optional interpolation scheme
        }
    }

In order to use tableFile, we do in the following way as being told in How to use 2 tableFile?

<entryName> tableFile;
<entryName>Coeffs
         {
             ...
         }

In my case, the <entryName> is uniformValue.

Happy that Caelan could act before me (thanks) - sorry for being late.

Having said that I couldn't find any particular commit in the .org repo which deprecated the "csvFile" option (or at least stating it in a commit message). Might be worth to double check if necessary.

[Marpole]

Thanks again, Herpes, for paying attention to this thread.

The User Guide (v8) still have type csvFile printed. This could cause some confusions. I installed OpenFOAM v8 a few months ago. Because of this, I moved back to OpenFOAM v7 to work on my projects until I have time now to investigate this issue.

[HPE]

I would stick with v8 (or even the develop branch) instead of v7 just merely because of bug fixes involving in the newer version. Just my humble opinion.

Good luck.
