Requesting output for Noise and Vibration analyses

You use a MATV Vibro-Acoustic Output Requests, ATV Vibro-Acoustic Output Requests, or Inverse Numerical Acoustics Output Requests modeling object to request the types of output the software lists to the .sc_h5 file when you solve your Noise and Vibration solution. When you create an output request, you select each type of result you want the solver to output. For example, if you want the software to output acoustic pressure at microphones, select the Acoustic Pressure check box in the Properties group of the MATV Vibro-Acoustic Output Requests dialog box.

Types of output available

The MATV Vibro-Acoustic Output Requests, ATV Vibro-Acoustic Output Requests, and Inverse Numerical Acoustics Output Requests dialog boxes let you select specific output types.

Output request type	Applicable analysis type	Applicable solution type	Description
Acoustic Intensity	Vibro-Acoustic	ATV responseMATV response	Requests output of acoustic intensity.
Acoustic Particle Velocity	Vibro-Acoustic	Inverse numerical acoustics	Requests output of acoustic particle velocity.
Acoustic Power	Vibro-Acoustic	ATV responseMATV response	Requests output of acoustic power.
Acoustic Pressure	Vibro-Acoustic	ATV responseMATV response	Requests output of acoustic pressure.
Element Equivalent Radiated Power	Vibro-Acoustic	ATV response	Requests output of equivalent radiated power on structural elements on all available panels.Note: You can request this output only when you also request output of equivalent radiated power on all available panels.
Equivalent Radiated Power	Vibro-Acoustic	ATV response	Requests output of equivalent radiated power on all available panels.
Modal Acoustic Transfer Vectors	Vibro-Acoustic	MATV response	Requests output of modal acoustic transfer vectors.
Panel Contribution Acoustic Transfer Vectors	Vibro-Acoustic	MATV response	Requests panel contributions to acoustic transfer vectors in contribution analyses.
Panel Contribution Modal Acoustic Transfer Vectors	Vibro-Acoustic	MATV response	Requests panel contributions to modal acoustic transfer vectors in contribution analyses.
