Boundary layers along edges and embedded lines
Hi and thanks for a good software.
I am interested in creating boundary layers around boundaries in combination with boundary layers around embedded lines that touch the boundary. What would be the best way to set up gmsh for this? Any hints would be much appreciated! I've tried various fields, but to no avail, but perhaps I have not tested them extensively enough.
This model problem is in 2D, but ultimately I am interested in 3D with multiple embedded, possibly intersecting surfaces that touch external and/or internal boundaries.
Below is a picture with an embedded line. This is nice, but missing the boundary layers:
Below is a picture where there is a boundary layer on the edge, but the line is not embedded. It may be possible to "fake" embedding, since the line is aligned with the boundary layer mesh lines, but I'd like to avoid this special solution. I don't think this is viable since I also want boundary layers on the embedded line.
Here's the code where I used BoundaryLayer
to create boundary layers.

Thank you.
