plfar

Mapdl.plfar(lab='', option='', phi1='', phi2='', nph1='', theta1='', theta2='', ntheta='', val1='', val2='', val3='', **kwargs)

Plots pressure far fields and far field parameters.

APDL Command: PLFAR

Parameters
lab

Parameters to plot :

PRES - Acoustic parameters

PROT - Acoustic parameters with the y-axis rotated extrusion

option

Plot option, based on the specified plot parameter type:

phi1, phi2

Starting and ending φ angles (degrees) in the spherical coordinate system. Defaults to 0.

nphi

Number of divisions between the starting and ending φ angles for data computations. Defaults to 0.

theta1, theta2

Starting and ending θ angles (degrees) in the spherical coordinate system. Defaults to 0 in 3-D and 90 in 2-D.

ntheta

Number of divisions between the starting and ending θ angles for data computations. Defaults to 0.

val1

Radius of the sphere surface. Used only when Option = SUMC, SUMP, PHSC, PHSP, SPLC, SPLP, SPAC, SPAP, PSCT, PSPL, TSCT, or TSPL.

val2

When Option = SPLC, SPLP, SPAC, or SPAP: Reference rms sound pressure. Defaults to 2x10-5 Pa.

val3

When Lab = PRES: Thickness of 2-D model extrusion in the z direction (no default).

Notes

The PLFAR command plots pressure far fields and far field parameters as determined by the equivalent source principle. Use this command to plot pressure and acoustic parameters. See the HFSYM command for the model symmetry and the HFANG command for spatial radiation angles.

When Option = PWL no plot is generated, but the sound power level appears in the output.

To retrieve saved equivalent source data, issue the SET,Lstep,Sbstep,,REAL command.
