ASCRES, Opt
Specifies the output type for an acoustic scattering analysis.
Opt
Output option:
TOTAL | — | Output the total pressure field (default). |
SCAT | — | Output the scattered pressure field. |
Use the ASCRES command to specify the output type for an acoustic scattering analysis.
The scattered option (Opt
= SCAT)
provides a scattered pressure output, psc,
required for calculating target strength (TS).
The default behavior (Opt
= TOTAL)
provides a sum of the incident and scattering fields, ptotal = pinc + psc.
Issue the AWAVE command to define the incident
pressure pinc. If the AWAVE command is defined with Opt2
= INT, only
the total pressure field is output regardless of the ASCRES,Opt
command.
