hi foamers!

I have a problem with my surfacelayers. i use to simulate a flow over a endless circular cylinder. How you can see on the picture my layers do not go till the frontAndBack-patches. Is it normal that the layers where built from the outside-patches? I am new in OpenFOAM please help me!

// Settings for the layer addition.
addLayersControls
{
relativeSizes true;

// Per final patch (so not geometry!) the layer information
layers
{
geodata1_patch0
{
nSurfaceLayers 7;
}
}

// Expansion factor for layer mesh
expansionRatio 1.0;

//- Wanted thickness of final added cell layer. If multiple layers
// is the
// thickness of the layer furthest away from the wall.
// Relative to undistorted size of cell outside layer.
finalLayerThickness 0.9;

//- Minimum thickness of cell layer. If for any reason layer
// cannot be above minThickness do not add layer.
// Relative to undistorted size of cell outside layer.
minThickness 0.1;

//- If points get not extruded do nGrow layers of connected faces that are
// also not grown. This helps convergence of the layer addition process
// close to features.
nGrow 1;

best regards
Wolfgang
