<div>I want to create a boundar layer at the bottom of the blade, you can see in the attached picture. I tried a lot of things to create it, using surface, edges and nodes, but it doesn´t work. Can you please help me?</div>
<div>Here is my text in the .geo-file. The model i´m using is a .step-file with big dimensions (length 32000mm).</div>

<div>
<div>Mesh.CharacteristicLengthFactor = 1.;<br/>
Geometry.OCCSewFaces = 1.;<br/>
//Geometry.OCCConnectFaces = 1.;<br/>
Geometry.Tolerance = 0.02;</div>

Surface Loop(19) = {5, 8, 7, 1, 9, 2, 3, 6, 4};</div>
<div>Volume(20) = {19};</div>
<div> </div>
<div>Characteristic Length {9, 10, 7, 8} = 200.;<br/>
Characteristic Length {5, 6, 11, 12} = 400.;</div>
<div><br/>
Field[1] = BoundaryLayer;<br/>
Field[1].EdgesList = {6,14,15,16};<br/>
//Field[1].NodesList = {5,6,11,12};<br/>
Field[1].FanNodesList = {5,6,11,12};<br/>
//Field[1].FacesList = {1};<br/>
//Field[1].hfar = 150.;<br/>
Field[1].hwall_n = 50.;<br/>
Field[1].hwall_t = 80.;<br/>
Field[1].thickness = 200.;<br/>
//Field[1].Quads = 0;<br/>
Field[1].ratio = 1;</div>
<div>BoundaryLayer Field = 1;</div>

<div>Thank you, best regards</div>
