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(
    project=project_full_name,
    design="Cassegrain_",
    solution_type="SBR+",
    version=aedt_version,
    new_desktop=True,
    non_graphical=non_graphical
)

source = pyaedt.Hfss(project=target.project_name,
                     design="feeder",
                     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 0x000001E924140430>

Assign boundaries#

Assign boundaries.

target.assign_perfecte_to_sheets(["Reflector", "Subreflector"])
target.mesh.assign_curvilinear_elements(["Reflector", "Subreflector"])
<pyaedt.modules.Mesh.MeshOperation object at 0x000001E9241401F0>

Plot model#

Plot the model

source.plot(show=False, output_file=os.path.join(target.working_directory, "Source.jpg"), plot_air_objects=True)
target.plot(show=False, output_file=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")
<pyaedt.modules.report_templates.FarField object at 0x000001E92411BC10>

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()
