FfdSolutionDataExporter

class ansys.aedt.core.visualization.post.farfield_exporter.FfdSolutionDataExporter(app, sphere_name, setup_name, frequencies, variations=None, overwrite=True, export_touchstone=True, set_phase_center_per_port=True)

Class to enable export of embedded element pattern data from HFSS.

An instance of this class is returned from the ansys.aedt.core.Hfss.get_antenna_data() method. This method allows creation of the embedded element pattern files for an antenna that have been solved in HFSS. The metadata_file properties can then be passed as arguments to instantiate an instance of the ansys.aedt.core.ansys.aedt.core.visualization.advanced.farfield_visualization.FfdSolutionData class for subsequent analysis and postprocessing of the array data.

Note that this class is derived from the FfdSolutionData class and can be used directly for far-field postprocessing and array analysis, but it remains a property of the ansys.aedt.core.Hfss application.

Parameters:

appansys.aedt.core.Hfss

HFSS application instance.

sphere_namestr

Infinite sphere to use.

setup_namestr

Name of the setup. Make sure to build a setup string in the form of "SetupName : SetupSweep".

frequencieslist

Frequency list to export. Specify either a list of strings with units or a list of floats in Hertz units. For example, ["9GHz", 9e9].

variationsdict, optional

Dictionary of all families including the primary sweep. The default value is None.

overwritebool, optional

Whether to overwrite the existing far field solution data. The default is True.

export_touchstonebool, optional

Whether to export touchstone file. The default is False. Working from 2024 R1.

set_phase_center_per_portbool, optional

Set phase center per port location. The default is True.

Examples

>>> from ansys.aedt.core
>>> app = ansys.aedt.core.Hfss(version="2025.2", design="Antenna")
>>> setup_name = "Setup1 : LastAdaptive"
>>> frequencies = [77e9]
>>> sphere = "3D"
>>> data = app.get_antenna_data(frequencies, setup_name, sphere)
>>> data.plot_3d(quantity_format="dB10")
