sources_fft

class ansys.fluent.core.solver.tui_241.main_menu.define.models.acoustics.sources_fft(service, version, mode, path)

Bases: TUIMenu

Enters the acoustic sources fast Fourier transform (FFT) menu, to compute Fourier spectra from acoustic source data (ASD) files, create postprocessing variables for the pressure signals, and write CGNS files of the spectrum data.

Classes:

clean_up_storage_area(service, version, ...)	De-allocates memory used to store the pressure histories and their Fourier spectra, as well as any created surface variables for the visualization.
compute_fft_fields(service, version, mode, path)	Computes FFT of the read pressure histories.
fft_surface_variables(service, version, ...)	Enters the menu to create surface variables from the computed Fourier spectra for visualization.
read_asd_files(service, version, mode, path)	Reads ASD files to perform FFT of the pressure history field.
write_cgns_files(service, version, mode, path)	Writes surface pressure spectra in CGNS format, which can be used for one-way coupling with Ansys Mechanical in the frequency domain.

class clean_up_storage_area(service, version, mode, path)

Bases: TUIMethod

De-allocates memory used to store the pressure histories and their Fourier spectra, as well as any created surface variables for the visualization.

class compute_fft_fields(service, version, mode, path)

Bases: TUIMethod

Computes FFT of the read pressure histories. The computed spectra replace the pressure histories in memory.

class read_asd_files(service, version, mode, path)

Bases: TUIMethod

Reads ASD files to perform FFT of the pressure history field.

class write_cgns_files(service, version, mode, path)

Bases: TUIMethod

Writes surface pressure spectra in CGNS format, which can be used for one-way coupling with Ansys Mechanical in the frequency domain.
