Hi,<br><br>I've been successfully using gmsh for some time, but now I would like to specify a much denser mesh around one of the structures in my geometry. I have tried using the boundary layer, box, and attractor fields to control the characteristic length but they seem to be having no effect on the generated mesh.<br>
<br>Attached is my geometry, I would like to have a characteristic length in the region of 1e-8 around the cantilever (or 'diving board') feature in the centre of the geometry. Is this characteristic length too small I wonder? How should I achieve the desired effect? The attached file has the boundary layer that I would like to use, but it has no effect on the mesh density.<br>
<br>Thank You in advance for any pointers you can share with me.<br><br>Regards,<br>John Parkin<br clear="all"><br>-- <br>PhD Student to Dr G. Haehner<br>School of Chemistry<br>
