SBR+: HFSS to SBR+ time animation

This example shows how you can use PyAEDT to create an SBR+ time animation and save it to a GIF file. This example works only on CPython.

Perform required imports.

Perform required imports.

import os
from ansys.aedt.core import Hfss, downloads

Set AEDT version

Set AEDT version.

aedt_version = "2024.2"

Set non-graphical mode

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

non_graphical = False

Launch AEDT and load project

Launch AEDT and load the project.

project_file = downloads.download_sbr_time()

hfss = Hfss(project=project_file, version=aedt_version, non_graphical=non_graphical, new_desktop=True)

hfss.analyze()

Get solution data

Get solution data. After simulation is performed, you can load solutions in the solution_data object.

solution_data = hfss.post.get_solution_data(expressions=["NearEX", "NearEY", "NearEZ"],
                                            variations={"_u": ["All"], "_v": ["All"], "Freq": ["All"]},
                                            context="Near_Field",
                                            report_category="Near Fields")

Compute IFFT

Compute IFFT (Inverse Fast Fourier Transform).

t_matrix = solution_data.ifft("NearE", window=True)

Export IFFT to CSV file

Export IFFT to a CSV file.

frames_list_file = solution_data.ifft_to_file(coord_system_center=[-0.15, 0, 0], db_val=True,
                                              csv_path=os.path.join(hfss.working_directory, "csv"))

Plot scene

Plot the scene to create the time plot animation

hfss.post.plot_scene(frames=frames_list_file, gif_path=os.path.join(hfss.working_directory, "animation.gif"),
                     norm_index=15, dy_rng=35, show=False, view="xy", zoom=1)
