Hi,

I am trying to create boundary layers around some walls in my model but there is something screwing up.

1. When I run the code only with BoundaryLayer 1 it works. But if I run it with both BoundaryLayers it only creates BoundaryLayer 2.

2. BoundaryLayer 2 isn't working correct (see picture).


Does anyone know how the soultion of my problems could be.

capillary = 0.0001;
Jet_Disrupter = 0.0001;
Walls = 0.001;

Point(1) = {0, 0, 0, capillary};
Point(2) = {0.006, 0, 0, capillary};
Point(3) = {0.006, 0.000254, 0, capillary};
Point(4) = {0.006, 0.0008, 0, Walls};
Point(5) = {0.004, 0.0008, 0, Walls};
Point(6) = {0.004, 0.0064, 0, Walls};
Point(7) = {0, 0.0064, 0, Walls};
Point(8) = {0, 0.0123, 0, Walls};
Point(9) = {0.0045, 0.0123, 0, Walls};
Point(10) = {0.0595, 0.0123, 0, Walls};
Point(11) = {0.1043, 0.0011, 0, Walls};
Point(12) = {0.1045, 0.0011, 0, Walls};
Point(13) = {0.1045, 0.0123, 0, Walls};
Point(14) = {0.1300, 0.0123, 0, Walls};

Hello,

Thanks for sharing your script/code, I found your post really helpful to make an boundary layer, have you tried been successful in your case? Any further comment will be a great help, thanks in advance.
