SBR+: HFSS to SBR+ coupling

This example shows how you can use PyAEDT to create an HFSS SBR+ project from an HFSS antenna and run a simulation.

Perform required imports

Perform required imports and set up the local path to the path for the PyAEDT directory.

import os
import pyaedt

project_full_name = pyaedt.downloads.download_sbr(pyaedt.generate_unique_project_name(project_name="sbr_freq"))

Set AEDT version

Set AEDT version.

aedt_version = "2024.1"

Set non-graphical mode

Set non-graphical mode. You can set non_graphical either to True or False.

non_graphical = False

Define designs

Define two designs, one source and one target, with each design connected to a different object.

target = pyaedt.Hfss(
    projectname=project_full_name,
    designname="Cassegrain_",
    solution_type="SBR+",
    specified_version=aedt_version,
    new_desktop_session=True,
    non_graphical=non_graphical
)

source = pyaedt.Hfss(projectname=target.project_name,
                     designname="feeder",
                     specified_version=aedt_version,
                     )

  self._logger = val

Define linked antenna

Define a linked antenna. This is HFSS far field applied to HFSS SBR+.

target.create_sbr_linked_antenna(source, target_cs="feederPosition", field_type="farfield")

<pyaedt.modules.Boundary.NativeComponentObject object at 0x000002716EE64BE0>

Assign boundaries

Assign boundaries.

target.assign_perfecte_to_sheets(["Reflector", "Subreflector"])
target.mesh.assign_curvilinear_elements(["Reflector", "Subreflector"])

<pyaedt.modules.Mesh.MeshOperation object at 0x000002716EF4E6E0>

Plot model

Plot the model

source.plot(show=False, export_path=os.path.join(target.working_directory, "Source.jpg"), plot_air_objects=True)
target.plot(show=False, export_path=os.path.join(target.working_directory, "Target.jpg"), plot_air_objects=False)

Create setup and solve

Create a setup and solve it.

setup1 = target.create_setup()
setup1.props["RadiationSetup"] = "ATK_3D"
setup1.props["ComputeFarFields"] = True
setup1.props["RayDensityPerWavelength"] = 2
setup1.props["MaxNumberOfBounces"] = 3
setup1["RangeType"] = "SinglePoints"
setup1["RangeStart"] = "10GHz"
target.analyze()

True

Plot results

Plot results.

variations = target.available_variations.nominal_w_values_dict
variations["Freq"] = ["10GHz"]
variations["Theta"] = ["All"]
variations["Phi"] = ["All"]
target.post.create_report("db(GainTotal)", target.nominal_adaptive, variations=variations,
                          primary_sweep_variable="Theta", report_category="Far Fields", context="ATK_3D")

Plot results outside AEDT

Plot results using Matplotlib.

solution = target.post.get_solution_data(
    "GainTotal",
    target.nominal_adaptive,
    variations=variations,
    primary_sweep_variable="Theta",
    context="ATK_3D",
    report_category="Far Fields",
)
solution.plot()

No artists with labels found to put in legend.  Note that artists whose label start with an underscore are ignored when legend() is called with no argument.

Release AEDT

Release AEDT and close the example.

target.release_desktop()

True
