Simulate the propagation of sound in viscous medium via the MP command.

Apply the various analytic sources (in an acoustic radiation or scattering analysis) to the inside or outside of the model via the AWAVE command. Analytic sources include plane wave, monopole/pulsating sphere, dipole, bare loudspeaker, and back-enclosed loudspeaker sources.

Apply the various mass sources to the model via the BF, BFK, BFL, BFA and BFV commands. Mass sources include point, line, surface, and volume sources.

Apply the surface normal velocity to the exterior surface of the model via the SF and SFA commands.

Apply the impedance boundary to the acoustic-structural interface via the SF and SFA commands.

Apply the impedance sheet load to the inside of the model via the BF and BFA commands.

Apply the Robin boundary condition to the exterior surface of model for radiation or scattering analysis via the SF and SFA commands.

Select the symmetric algorithm for FSI modal analysis via KEYOPT(2) = 2, or for full harmonic FSI analysis via using KEYOPT(2) = 3, when using fluid elements FLUID30, FLUID220 and FLUID221.

Select the total-field method for acoustic scattering analysis with analytic wave sources and PML or Robin boundary condition.

Select the pure scattered-field method for either acoustic scattering or radiation analysis with analytic wave sources and PML or Robin boundary condition via the HFSCAT command.

Define a sloshing surface via the SF and SFA commands.

Plot and print near- and far-field pressure, sound pressure level, directivity, sound power level, far-field scattered pressure, and target strength values via the PLNEAR, PLFAR, PRNEAR, and PRFAR commands.

Plot and print the nodal sound pressure level (SPL) and contour pattern via the PLNSOL, PRNSOL, NSOL, PLVAR and PRVAR commands.

The pressure L²-norm squares are stored in the element summable miscellaneous table for fluid elements FLUID30, FLUID220 and FLUID221.

The FSI surface between the acoustic elements and solid structural elements can be automatically identified if the SF command is not issued.

The equivalent source surface for near- and far-field can be automatically identified if the SF command is not issued.
