writeFormat and timeFormat in functions subDict in controlDict

deal foamers,

i am wondering if we can set the writeFormat and timeFormat in functions sub-dictionary in the controlDict.

the functionObjects i am using are faceSource and cellSource. and i test with

Code:

writeFormat bababa;

timeFormat bababa;

both not work. no error message. and the timeFormat and writeFormat set in controlDict seem not valid for data output by functionObject.

if there is a method to do this, please give me some hints.

thanks for your attention.

Quick answer: I've checked the source code and those controls are not available independently for each function object.

As for the format... yeah, it's hard-coded to a specific format: https://github.com/OpenFOAM/OpenFOAM...jectFile.C#L39

Please report this in the bug tracker: http://www.openfoam.org/bugs/

i will report it right now.

Hi,

have there been any changes for the most recent versions?

I found a source for OpenFOAM V2006

(https://www.openfoam.com/documentati...8H_source.html)

which says to use

Code:

     surfaces 

     {

 

         type            surfaces;

 

         fields          ( p );

 

         surfaceFormat   boundaryData;

 

         formatOptions

 

         {

 

             boundaryData

 

             {

 

                 format  binary;

 

             }

 

         }

 

         surfaces

 

         {

 

             outlet

 

             {

 

                 type            patch;

 

                 patches         (outlet);

 

                 interpolate     false;

 

             }

 

         }

 

     }

but it does not work for v1902 (the files are still in ASCII format).

I found the file OpenFOAM-v1912/tutorials/incompressible/pimpleFoam/LES/vortexShed/system/controlDict

in which the same code is used for ensight. It works for e.g. the ensight format but not for boundaryData which is just written in ASCI.

Code:

    cuttingPlane

    {

        type            surfaces;

        libs            (sampling);

        writeControl    timeStep;

        writeInterval   1;

        timeStart       0;



        surfaceFormat   boundaryData; //ensight;

        formatOptions

        {

            boundaryData //ensight

            {

                format binary;

                collateTimes true;

            }

        }

        fields          (U);



        interpolationScheme cellPoint;



        surfaces

        (

            zNormal

            {

                type            cuttingPlane;

                planeType       pointAndNormal;

                pointAndNormalDict

                {

                    point       (0 0 -0.01);

                    normal      (0 0 1);

                }

                interpolate     false;

            }

        );

    }

I might give OpenFOAM V2006 a try.

Best regards,

Lukas
