impedance_data_fitting

class ansys.fluent.core.solver.tui_231.main_menu.define.boundary_conditions.impedance_data_fitting(path, service)

Bases: TUIMenu

Enters the impedance data fitting menu, which provides text commands that can be helpful when you are using the impedance boundary condition (IBC).

Methods:

absorption_data(*args, **kwargs)	Reads an input file with experimental absorption coefficient data in the frequency domain and then computes the terms needed for an approximation of the reflection coefficient as a series of poles / residues in the time domain.
convergence_tolerance(*args, **kwargs)	Sets the convergence tolerance, which is an accuracy that is used for completing the iterative fitting procedure in the calculations performed from the define/boundary-conditions/impedance-data-fitting/ text command menu.
impedance_data(*args, **kwargs)	Reads an input file with experimental specific impedance data in the frequency domain and then computes the terms needed for an approximation of the reflection coefficient as a series of poles / residues in the time domain.
import_parameters(*args, **kwargs)	Reads a pole / residue file with impedance parameters in the time domain and applies them to a specified boundary condition.
iterations(*args, **kwargs)	Sets the number of internal iterations used for the calculations performed from the define/boundary-conditions/impedance-data-fitting/ text command menu.
reflection_data(*args, **kwargs)	Reads an input file with experimental reflection coefficient data in the frequency domain and then computes the terms needed for an approximation of the reflection coefficient as a series of poles / residues in the time domain.
residue_tolerance(*args, **kwargs)	Sets the residue tolerance, which is the minimum value of residues that are kept in the fitting performed from the define/boundary-conditions/impedance-data-fitting/ text command menu.
verbosity(*args, **kwargs)	Sets the verbosity of the progress messages during the fitting performed from the define/boundary-conditions/impedance-data-fitting/ text command menu.

absorption_data(*args, **kwargs)

Reads an input file with experimental absorption coefficient data in the frequency domain and then computes the terms needed for an approximation of the reflection coefficient as a series of poles / residues in the time domain. The resulting terms are printed in the console, and can be written to a pole / residue file (which can be imported and the impedance parameters applied to a boundary condition using the define/boundary-conditions/impedance-data-fitting/import-parameters text command). You can also write a file with fitted frequency / impedance data, which can be compared to the input data to evaluate how well it fits.

convergence_tolerance(*args, **kwargs)

Sets the convergence tolerance, which is an accuracy that is used for completing the iterative fitting procedure in the calculations performed from the define/boundary-conditions/impedance-data-fitting/ text command menu. By default, the tolerance is set to 1e-6.

impedance_data(*args, **kwargs)

Reads an input file with experimental specific impedance data in the frequency domain and then computes the terms needed for an approximation of the reflection coefficient as a series of poles / residues in the time domain. The resulting terms are printed in the console, and can be written to a pole / residue file (which can be imported and the impedance parameters applied to a boundary condition using the define/boundary-conditions/impedance-data-fitting/import-parameters text command). You can also write a file with fitted frequency / impedance data, which can be compared to the input data to evaluate how well it fits.

import_parameters(*args, **kwargs)

Reads a pole / residue file with impedance parameters in the time domain and applies them to a specified boundary condition.

iterations(*args, **kwargs)

Sets the number of internal iterations used for the calculations performed from the define/boundary-conditions/impedance-data-fitting/ text command menu. By default, the number of iterations is set to 20.

reflection_data(*args, **kwargs)

Reads an input file with experimental reflection coefficient data in the frequency domain and then computes the terms needed for an approximation of the reflection coefficient as a series of poles / residues in the time domain. The resulting terms are printed in the console, and can be written to a pole / residue file (which can be imported and the impedance parameters applied to a boundary condition using the define/boundary-conditions/impedance-data-fitting/import-parameters text command). You can also write a file with fitted frequency / impedance data, which can be compared to the input data to evaluate how well it fits.

residue_tolerance(*args, **kwargs)

Sets the residue tolerance, which is the minimum value of residues that are kept in the fitting performed from the define/boundary-conditions/impedance-data-fitting/ text command menu. This residue check helps to eliminate parasitic poles. By default, the tolerance is set to 1e-6.

verbosity(*args, **kwargs)

Sets the verbosity of the progress messages during the fitting performed from the define/boundary-conditions/impedance-data-fitting/ text command menu. Setting this to 1 results in messages being printed in the console as the fitting calculation progresses. The default value of 0 suppresses this output.
