Definitions

Argument Options Description
format <H3D, PCH, blank>
H3D
Results are output in Hyper3D format (.h3d file).
PCH
Results are output in Punch format (.pch file).
Blank (Default)
Results are output in all active formats for which the result is available.
option <YES, ALL, NO, NONE, SID>
YES, ALL (Default)
Intensity is output for all acoustic grids.
NO, NONE
Intensity is not output.
SID
If a set ID is given, the acoustic intensity is output only for the fluid grids listed in that set.

Comments

  1. The expression for acoustic intensity is related to the nodal pressure ( p MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbwvMCKf MBHbqefqvATv2CG4uz3bIuV1wyUbqedmvETj2BSbqefm0B1jxALjhi ov2DaebbnrfifHhDYfgasaacH8srps0lbbf9q8WrFfeuY=Hhbbf9v8 qqaqFr0xc9pk0xbba9q8WqFfea0=yr0RYxir=Jbba9q8aq0=yq=He9 q8qqQ8frFve9Fve9Ff0dmeaacaGacmGadaWaaiqacaabaiaafaaake aacaWGWbaaaa@39CC@ ) and the complex conjugate of the particle velocity ( ν * MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbwvMCKf MBHbqefqvATv2CG4uz3bIuV1wyUbqedmvETj2BSbqefm0B1jxALjhi ov2DaebbnrfifHhDYfgasaacH8srps0lbbf9q8WrFfeuY=Hhbbf9v8 qqaqFr0xc9pk0xbba9q8WqFfea0=yr0RYxir=Jbba9q8aq0=yq=He9 q8qqQ8frFve9Fve9Ff0dmeaacaGacmGadaWaaiqacaabaiaafaaake aacqaH9oGBcaGGQaaaaa@3B3D@ ), given by:(1)
