Hello for my flow over an airfoil simulation i get the following error:

Reading field U
-->FOAM FATAL IO erro:
Cannot find patchField entry for airfoil....

My boundry file looks like this:

(
outlet
{
type outlet;
nFaces 132;
startFace 28303;
}
inlet
{
type inlet;
nFaces 216;
startFace 28435;
}
airfoil
{
type wall;
inGroups 1(wall);
nFaces 70;
startFace 28651;
}
frontAndBackPlanes
{
type empty;
inGroups 1(empty);
nFaces 28512;
startFace 28721;
}
)

And my U file (where I guess there is a problem):

dimensions [0 1 -1 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{
outlet
{
type zeroGradient;
}

inlet
{
type fixedValue;
value uniform (19 2 0)
}

airfoil
{
type noSlip;
}

frontAndBackPlanes
{
type empty;
}
}

Does anyone know how to solve this error?
Kind regards TG
