Quality Metrics scenario

The Quality Metrics scenario is an acoustics post-processing scenario that you can use to assess:

• Computational effort and contribution of an element order associated with a frequency response analysis (SOL 108 and SOL 111) using the Simcenter Nastran FEM Adaptive Order method.

• Coupling quality associated with an MATV or ATV response analysis in a Simcenter 3D Noise and Vibration solution.

Computational effort and contribution of an element order

You can visualize the following with the Quality Metrics scenario in an XY plot:

• Analysis time for each frequency

• Memory allocated for each frequency

• Contribution of each element order to the result at a selected frequency

You can visualize the order of each element at a selected frequency in a contour plot.

Coupling quality

You can visualize the following Coupling Quality values with the Quality Metrics scenario in a 3D post view:

• Coupling quality between structural coupled and uncoupled faces

• Coupling quality between fluid coupled and uncoupled nodes

• Distance between structural and fluid coupled faces

Parameters

The following table lists the parameters available for defining Quality Metrics post-processing scenarios in an acoustic solution. They appear in the Parameters node of the Scenario Based Data-Visualization Navigator.

Parameter	Description
Element Order Contribution	Plots the contribution of each element order to the result at a selected frequency.
Order Per Element	Displays the order of each element at a selected frequency in a contour plot.
Time Per Frequency	Plots the analysis time used for each frequency.
Memory Per Frequency	Plots the memory used during the analysis for each frequency.
