ATV response workflow

Note:

For a workflow that creates an ATV Set, see ATV set workflow.

Step	Summary	Detailed help topic
1.	Open a Simulation file.	Open an existing Simulation file that contains a component FEM or assembly FEM file.The Simulation file can be the same one that was used for computing the ATV Set.	Simulation fileCreate a new Simulation file
2.	Replace the FEM component or assembly FEM with the ATV Set by editing the FEM representation.	Right-click the component FEM or assembly FEM that you will use as an ATV set and choose Edit Representation.Note: If you want to compute the response for a new ATV Set that, for example, contains different results, you reference the new ATV Set in the FE Model Component Representation dialog box or external file in the Acoustic Transfer Vector Set dialog box.

3.	Create the solution.	Create a new solution with Solver set to Simcenter 3D Noise and Vibration, Analysis Type set to Vibro-Acoustic, and Solution Type set to Acoustic Transfer Vector (ATV) Response.Alternatively, you can create a solution directly from a predefined load recipe to apply loads from an external file (for example, containing measurement data) to the simulation model.Note: Time-domain data must be first converted to frequency domain data or waterfall of time data with the Model and Load Pre-processing solution process.	Create or modify a solutionCreate a solution from a load recipeTransforming time-domain to frequency
4.	Define forcing frequencies.	Add Forcing Frequencies to the solution or solution subcases to excite the model.	Specifying forcing frequencies for a frequency response analysis
5.	Create output requests.	Request the desired output, such as acoustic pressure, panel contributions to acoustic pressure, and so on with the ATV Vibro-Acoustic Output Requests modeling object.	Requesting output for Noise and Vibration analyses
6.	Define the vibro-acoustic solution parameters.	Create a Fluid-Structure Interface Modeling Parameters modeling object, where you can specify parameters that control the fluid-structure interface (coupling) for the analysis.	Define fluid-structure interface modeling parameters (Noise and Vibration)
7.	(Skip this step when a solution created from a load recipe exists)Create load recipe.	Reference an external file, such as a Nastran (.op2), PCH (.pch), Simcenter HDF5 Data File (*.sc_h5), and so on that contains frequency, order, or RPM data.Note: Time-domain data must be first converted to frequency domain data or waterfall of time data with the Model and Load Pre-processing solution process.
8.	Solve the model.	Solve the model to generate the ATV response results.During this step, the pre-solver used by Simcenter 3D Noise and Vibration writes the results to a simulation_file_name-solution_name.sc_h5 file.	Solve the model
9.	Post-process the results.	Select the vibro-acoustic results and choose Post-processing Scenario.	Scenario-based post-processing
