Dear friends,
I'm trying to change the structure during the simulation. The code below is
one example. This code gives me a big error message. What is wrong with it?
res = 40 # pixels/um (originalmente, 20)
eps = 9 # dielectric constant of the hole
r = 0.4 # radius of the cylinder
sy = 2 # tamanho da célula na direção y
sx = 2 # tamanho da célula na direção x
cell = mp.Vector3(sx,sy,0)
geom = [mp.Cylinder(radius=r,
center=mp.Vector3(),
material=mp.Medium(epsilon=eps))]
pml_layers = [mp.PML(1.0)]
src = [mp.Source(mp.GaussianSource(0.2, fwidth=0.15),
component=mp.Ez,
center=mp.Vector3(),
size=mp.Vector3())]
def change_mat(sim):
t = sim.meep_time()
fn = t * 0.2
geom = [mp.Sphere(radius=r, center=mp.Vector3(fn))]
mp.set_materials_from_geometry(
sim.structure,
geom,
mp.Vector3(),
sim.eps_averaging,
sim.subpixel_tol,
sim.subpixel_maxeval,
sim.ensure_periodicity,
False,
sim.default_material,
None,
sim.extra_materials
)
sim = mp.Simulation(
cell_size=cell,
resolution=res
)
sim.run(mp.at_beginning(mp.output_epsilon),
mp.at_time(10, change_mat),
mp.at_end(mp.output_epsilon),
until=60)
