Cable modeling#

The Cable Modeling module includes several methods to work with the Cable Modeling HFSS Beta feature:

  • create_cable to create all available types of cables: bundle, straight wire and twisted pair.

  • update_cable_properties to update all cables properties for all cable types.

  • update_shielding to update only the shielding jacket type for bundle cable.

  • remove_cables to remove cables.

  • add_cable_to_bundle to add a cable or a list of cables to a bundle.

  • create_clock_source to create a clock source.

  • update_clock_source to update a clock source.

  • remove_source to remove a source.

  • remove_all_sources to remove all sources.

  • create_pwl_source to create a pwl source.

  • create_pwl_source_from_file to create a pwl source from file.

  • update_pwl_source to update a pwl source.

  • create_cable_harness to create a cable harness.

They are accessible through:

cable_modeling.Cable

Contains all common Cable features.

Cable bundle creation example:

from ansys.aedt.core import Hfss
from ansys.aedt.core.generic.DataHandlers import json_to_dict
from ansys.aedt.core.modules.cable_modeling import Cable

hfss = Hfss(projectname=project_path, specified_version="2023.1",
             non_graphical=False, new_desktop_session=True,
             close_on_exit=True, student_version=False)
# This call returns a dictionary out of the JSON file
cable_props = json_to_dict(json_path)
# This example shows how to manually change from script the cable properties
cable_props["Add_Cable"] = "True"
cable_props["Cable_prop"]["CableType"] = "bundle"
cable_props["Cable_prop"]["IsJacketTypeInsulation"] = "True"
cable_props["CableManager"]["Definitions"]["CableBundle"]["BundleParams"]["InsulationJacketParams"][
            "InsThickness"
        ] = "3.66mm"

            "JacketMaterial"
        ] = "pec"

            "InnerDiameter"
        ] = "2.88mm"
cable_props["CableManager"]["Definitions"]["CableBundle"]["BundleAttribs"]["Name"] = "Bundle_Cable_Insulation"
# This call returns the Cable class
cable = Cable(hfss, cable_props)
# This call creates the cable bundle
cable.create_cable()

Clock source creation example:

cable_props["CableManager"]["TDSources"]["ClockSourceDef"]["ClockSignalParams"]["PulseWidth"] = "23us"
cable_props["CableManager"]["TDSources"]["ClockSourceDef"]["TDSourceAttribs"]["Name"] = "clock_test_1"
# This call returns the Cable class
cable = Cable(hfss, cable_props)
# This call creates the clock source
cable.create_clock_source()

Cable harness creation example:

from ansys.aedt.core import Hfss
from ansys.aedt.core.generic.DataHandlers import json_to_dict
from ansys.aedt.core.modules.cable_modeling import Cable

# This call returns a dictionary out of the JSON file
cable_props = json_to_dict(json_path)
# This example shows how to manually change from script the cable harness properties
