give me an example for setting of a cell for run-time in swak type

could anyone send me an example on how a dictionary for obtaining a value in a cell by using swak4FOAM type during run?

That is called probes and you don't need swak for this. Have a look in the tutorials: OpenFOAM-2.2.x/tutorials/incompressible/pisoFoam/les/pitzDaily/system/controlDict

thanks.but the outputs of swak4FOAM functions I use are better arrange(I have nine probes)
current output is like so:

at not a good order.there isn't any swak function for probes?

Not sure what your problem with this output is. The only similar thing that swak offers is set with the type cloud. But that "only" allows you calculations and one output (or output with the dumpVariables-functionObject)

its like the attachment not arranged like in CODE tag.
and I dont know how to plot variables for each point.
couldn't it be in separated folders like swak's?

do you mean it doesn't have an output of value lists?just one result number in each time step or what?
isn't it appropriate by adding a expression?

Code:

createThrePointSet

    {

        type createSampledSet;

        outputControl timeStep;

        outputInterval 1;

        setName threePoints;

        set {

            type cloud;

            axis x;

            points (

                (0.1 0.14 0.0001)

                (0.0 0.02 0.0001)

                (-0.1 0.02 0.0001)

            );

        }

        writeSetOnConstruction true;

        autoWriteSet true;

        setFormat vtk;

    }

I don't understand you obsession with separate files for each point. You can always have a probe for each point separately .... done. Otherwise: load the file with all nine points into the Spreadsheet and delete the columns you don't need.

ok.resolved.thanks.
how can write in each time step like what swak does not each writing time?

Code:

probes

    {

        type            probes;

        functionObjectLibs ("libsampling.so");

        enabled         true;

        outputControl   outputTime;

        outputInterval  1;



        fields

        (

            p

            T

            U

        );



        probeLocations

        (

            ( 0 0.0005 0 )

            ( 0.0345 0.0005 0 )

            ( 0.069 0.0005 0 )

            ( 0 0.002 0 )

            ( 0.0345 0.002 0)

            ( 0.069 0.002 0 )

            ( 0 0.0035 0 )

            ( 0.0345 0.0035 0 )

            ( 0.069 0.0035 0 )

        );



    }



}

could you tell me a bit about type cloud?
