DBEM Acoustic, IBEM Acoustic, and IBEM Vibro-Acoustic Output Requests dialog boxes (Acoustics BEM)

Modeling Object
Name	Sets the name of the output request.
Label	Sets a unique integer for the modeling object.This label also appears in the Modeling Objects Manager dialog box, and you can filter the objects listed in that dialog box by their label.
Properties
Field Computation	The solver outputs only one acoustic field (scattered or total). This option is valid for all pressure, velocity, and intensity results.Incident+ScatteredComputes both incident and scattered (total) acoustic fields. The resulting total field is the sum of the incident and scattered fields.Scattered OnlyComputes and outputs only the scattered fields.An incident field with acoustic waves propagates toward the surface, and when it touches the surface, it is scattered in many directions. Hence, scattered fields ignore the strength of incident fields.

Function (SORT2)
Function (SORT2) (Pressure)	Specifies the pressure function (SORT2) output requests for a microphone mesh.All Microphone Nodes — Calculates pressure on all microphone nodes.All Isolated Microphone Nodes — Calculates pressure on all isolated microphone nodes.Selected Microphone Nodes — Lets you specify microphone nodes either by group reference or by directly selecting microphone nodes.For more information, see Group Reference options.None — Does not calculate pressure function (SORT2) results on microphone nodes.The following options appear for indirect BEM vibro-acoustic output requests. Panel Contributions to Acoustic Pressure — Computes the panel contributions to acoustic pressure on selected microphone nodes.Structural Modal Contributions to Acoustic Pressure — Computes the structural modal contributions to acoustic pressure on selected microphone nodes.
Acoustic Power
Specifies the acoustic power output requests on 2D microphone elements.
Function (SORT2)	Specifies the acoustic power output requests on 2D microphone elements.All 2D Microphone Meshes — Calculates the acoustic power on all 2D microphone meshes.Selected Groups of 2D Microphone Elements — Lets you specify the 2D microphone elements either by selecting existing group(s) or by creating new group(s).For more information, see Group Reference options.None — Does not calculate acoustic power function (SORT2) results on 2D microphone elements.The following options appear for indirect BEM vibro-acoustic output requests. Panel Contributions to Acoustic Power — Computes the panel contributions to acoustic power on all selected entities.Structural Modal Contributions to Acoustic Power — Computes the structural modal contributions to acoustic power on all selected entities.
Structural Results
Available for Indirect BEM vibro-acoustic output requests.
Vector (SORT1)
Specifies the displacement, velocity, and acceleration output requests on the selected entities.
Displacement	Requests displacement output on structural nodes in vector format.
Velocity	Requests velocity output on structural nodes in vector format.
Acceleration	Requests acceleration output on structural nodes in vector format.
Function (SORT2)
