You can use the plot_field() function to plot the structure on top of the simulated fields. For example:

# Run the simulation and get the data.
sim_data = tidy3d.web.run(simulation, task_name="task", path="data/data.hdf5", verbose=True)

# Plot the Ex field data and the structure.
ax = sim_data.plot_field(
  field_monitor_name="field",
  field_name="Ex",
  val='real',
  eps_alpha=0.2,
  phase=0,
)
