class main_menu.define.models.acoustics.sources_fft(path, service)#

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.

clean_up_storage_area(*args, **kwargs)#

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(*args, **kwargs)#

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

read_asd_files(*args, **kwargs)#

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

write_cgns_files(*args, **kwargs)#

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