Hello everyone,
I am trying to model a helical coil as shown in the Tutrial.
The following is the script that I am running.
from netgen.occ import *
from ngsolve import *
from ngsolve.webgui import Draw
cyl = Cylinder((0,0,0), Z, r=0.01, h=0.03).faces[0]
heli = Edge(Segment((0,0), (12*pi, 0.03)), cyl)
ps = heli.start
vs = heli.start_tangent
pe = heli.end
ve = heli.end_tangent
e1 = Segment((0,0,-0.03), (0,0,-0.01))
c1 = BezierCurve( [(0,0,-0.01), (0,0,0), ps-vs, ps])
e2 = Segment((0,0,0.04), (0,0,0.06))
c2 = BezierCurve( [pe, pe+ve, (0,0,0.03), (0,0,0.04)])
spiral = Wire([e1, c1, heli, c2, e2])
circ = Face(Wire([Circle((0,0,-0.03), Z, 0.001)]))
coil = Pipe(spiral, circ)
coil.faces.maxh=0.2
coil.faces.name="coilbnd"
coil.faces.Max(Z).name="in"
coil.faces.Min(Z).name="out"
coil.faces.col=(184/256, 115/256, 51/256)
coil.mat("coil")
crosssection = coil.faces.Max(Z).mass
ea = { "euler_angles" : (-130, -73, 0), "radius" : 0.025 }
Draw (coil, **ea)
When I run the script in JupyterHub, the drawing appears collapsed.
It is ok with JupyterLab. Does anyone know how to solve this?
