Dear Fellows

I have a rectangular -shaped grid which its bottom should be a wall with discontinuous distribution of one of scalars. In other words, for defining Ue (scalar) on the bottom wall of my grid I want to use a discontinuous distribution as follows:

At the bottom wall I have: y=0

-3<x<-2      Ue=0

-2<x<-0.5     Ue=1
-0.5<x<0.5     Ue=0
0.5<x<2       Ue=-1
2<x<3        Ue=0

I have attached the picture of the grid. I tried to use the following boundary condition to read the distribution from file:

downWall       
    {
    type            uniformFixedValue;
          uniformValue    csvFile;
          csvFileCoeffs
        {
                fileName         "$FOAM_CASE/myDataFile"
                outOfBounds      clamp;
                hasHeaderLine    true;
                refColumn        0;
                componentColumns 1; // vector example
        }
    }

I am using OF 2.1.x and the point is that I have looked at $FOAM_CASE /constant/polyMesh boundary file and my downwall has 95 faces:

downWall
    {
        type            wall;
        nFaces          95;
        startFace       3780;
    }

So I defined 95 rows in one colum as attached, however I am facing this error during execution:

Reading field Electric Potential Ue

Can Anybody hint me how is the correct way to read this boundary for downwall from a .CSV type file?
