PlotDirectivity

Plots the directivity graph of the specified DIR_ID

Overview

➡️ Plots the directivity graph of the specified “DIR_ID”

Arguments

Mandatory inputs

confDirId — Directivity Index

Identifier of the directivity sphere from “tableSourceDirectivity” parameter or train directivity if “tableSourceDirectivity” parameter is not filled (INTEGER) In case of train, you can use these values:

  • 0 = OMNIDIRECTIONAL

  • 1 = ROLLING

  • 2 = TRACTIONA

  • 3 = TRACTIONB

  • 4 = AERODYNAMICA

  • 5 = AERODYNAMICB

  • 6 = BRIDGE

Type: Integer

confFrequency — Frequency

Frequency to plot (INTEGER). 63, 125, 250, 500, 1000, 2000, 4000, 8000 (should match with the column of tableSourceDirectivity

Type: Integer

Optional inputs

confScaleMaximum — Maximum scale attenuation (dB)

Maximum scale attenuation (in dB)

Type: Double

Default: 0

confScaleMinimum — Minimum scale attenuation (dB)

Minimum scale attenuation (in dB)

Type: Double

Default: -35

tableSourceDirectivity — Source directivity table name

Name of the emission directivity table.🛠 If not specified the default is train directivity of CNOSSOS-EU The table must contain the following columns:

  • DIR_ID : identifier of the directivity sphere (INTEGER)

  • THETA : [-90;90] Vertical angle in degree. 0° front 90° top -90° bottom (FLOAT)

  • PHI : [0;360] Horizontal angle in degree. 0° front 90° right (FLOAT)

  • LW63, LW125, LW250, LW500, LW1000, LW2000, LW4000, LW8000 : attenuation levels in dB for each octave or third octave (FLOAT).
