FfdSolutionData#

class ansys.aedt.core.visualization.advanced.farfield_visualization.FfdSolutionData(input_file, frequency=None, variation=None, model_info=None, incident_power=None, touchstone_file=None)#

Provides antenna far-field data.

Read element pattern information in a JSON file generated by FfdSolutionDataExporter() and return the Python interface to plot and analyze the far-field data.

Parameters:

input_filestr: Metadata information in a JSON file.
frequencyfloat, optional: Active frequency in hertz (Hz). The default is None, in which case the first frequency is active.
variationstr, optional: Label to identify corresponding variation.
model_infodict, optional
incident_powerdict, optional: Dictionary with information of the incident power for each frequency. The default is None, in which case an empty dictionary is applied. From AEDT 2024.1, this information is available from the XML input file. For example, the dictionary format for a two element farfield data = incident_power[“1GHz”] data = [1, 0.99]
touchstone_filestr, optional: Touchstone file name. The default is None.

Examples

>>> from ansys.aedt.core
>>> from ansys.aedt.core.visualization.advanced.farfield_visualization import FfdSolutionData
>>> app = ansys.aedt.core.Hfss(version="2023.2", design="Antenna")
>>> data = app.get_antenna_data()
>>> metadata_file = data.metadata_file
>>> app.release_desktop()
>>> farfield_data = FfdSolutionData(input_file=metadata_file)
>>> farfield_data.plot_3d(quantity_format="dB10")
