fft_multi_harmonic_minmax class

Namespace: Ans.DataProcessing.operators.math

Summary

Evaluate min max fields on multi harmonic solution. min and max fields are calculated based on evaluating a fourier series sum wrt rpms and using the gradient method for adaptive time steping

available inputs: fields_container (FieldsContainer), rpm_scoping (Scoping) (optional), fs_ratio (Int32) (optional), num_subdivisions (Int32) (optional), max_num_subdivisions (Int32) (optional), num_cycles (Int32) (optional), use_harmonic_zero (bool) (optional), calculate_time_series (bool) (optional), substeps_selector (IList int, System.Collections.IEnumerable) (optional)

available outputs: field_min (FieldsContainer), field_max (FieldsContainer), all_fields (FieldsContainer)

Example

Inputs

fields_container

Type: LinkableInput

rpm_scoping

rpm scoping, by default the fourier series sum is evaluated using all the rpms

Type: LinkableInput

fs_ratio

field or fields container with only one field is expected

Type: LinkableInput

num_subdivisions

connect number subdivisions, used for uniform discretization

Type: LinkableInput

max_num_subdivisions

connect max number subdivisions, used to avoid huge number of sudivisions

Type: LinkableInput

num_cycles

Number of cycle of the periodic signal (default is 2)

Type: LinkableInput

use_harmonic_zero

use harmonic zero for first rpm (default is false)

Type: LinkableInput

calculate_time_series

calculates time series output (output pin 2), setting it to false enhance performance if only min/max are required (default is true)

Type: LinkableInput

substeps_selector

substeps to evaluate (frequencies), by default the operator is evaluated using all the available steps

Type: LinkableInput

Outputs

field_min

Type: LinkableOutput

field_max

Type: LinkableOutput

all_fields

Type: LinkableOutput
