Error using delaunayTriangulation when calling mesh() on a pcbStack

Hi! this is the first time I ask a question here I hope im doing everthing right. Well, I’m trying to simulate the EH fields of a 2 layer pcb coil, I import the files and make the pcbStack with the following code:
P = gerberRead("gerber/6L_planar_transformerv3-F_Cu.gbr", …
"gerber/6L_planar_transformerv3-In1_Cu.gbr", …
"gerber/6L_planar_transformerv3-PTH.drl");
pb2 = pcbStack(P);
f_cu=pb2.Layers{2};
in1_cu=pb2.Layers{4};
p = pcbStack;
p.BoardThickness=0.203e-3*1+1e-3;
p.ViaDiameter=0.1e-3;
d1 = dielectric("FR4");
d1.Thickness = 0.203e-3;
air = dielectric("Air");
air.Thickness = 1e-3;
p.BoardShape = antenna.Rectangle(Length=60e-3, Width=60e-3,Center=[0.1187 -0.0775]);
%p.Layers = {f_cu,d1,in1_cu,d1,in2_cu,d1,in3_cu,d1,d1,in4_cu,d1,b_cu};
p.Layers={air,f_cu,d1,in1_cu,air}
p.FeedDiameter = 0.1e-3;
p.FeedLocations = [146.1e-3 -72e-3 2;]
p.ViaLocations = [143e-3 -77.5e-3 2 4;
117.5e-3 -77.5e-3 2 4]
show(p)

The reason I’m importing the pcbStack like that is that I’m planning on simulating a planar transformer EH fields and the gerberRead() only allows for 2 layered pcb, this way i can add more layers by importing more gerber files. However when I run
mesh(p)

After some 20 minutes of the program running, it returns the following errors:
Error using delaunayTriangulation
Enforcing Delaunay constraints leads to unstable repeated constraint intersections.
This may be due to near coincident intersecting constraints or near duplicate points.

And since some functions of the RF toolbox like current() EHFields() first call mesh() I cant run simulations of my design. I don’t know if the size could be the reason of the delaunayTriangulation failure or something is wrong with my setupHi! this is the first time I ask a question here I hope im doing everthing right.
