hi,
I am tring to get how the value of p changes over time at some points(votecies of the cell) ! the mesh is moving(without topology change) ,so I couldn't use "probes" which is stationary .
but I know we could use "sets" in controlDict for example
Code:
functions
{
    somePoints
    {
        type            sets;
        functionObjectLibs ("libsampling.so");
        outputControl   timeStep;
        outputInterval  1;
        setFormat   raw; 
        interpolationScheme cellPointFace;   
        fields
        (
            p
        );

        sets
        (
            movingpoints
            { 
               type            curve;  
               axis            xyz;
               points
               (
                  ( 0  0  0 )
                  ( 0  35 0 )
                  ( 0  70 0 )
                  ( -8 -0 0 )
                  ( -8 35 0 )
                  ( -8 70 0 )
               );
            }
         );
    }
}
then we could get a folder named somePoints in which there are many time folders , and each time folder has a file named movingpoints_p.xy which give the value of p at every point .

but what I really want is a file which we often get when using probes in controlDict . for example
Code:
#           x           -10 
#           y             0 
#           z             0 
#        Time
