The user can set parameter and compute the ERP.
Figure 1 Calculation dialog box
•Radiation Loss Factor (RLF): The default is 1.0.
•Sound Velocity (C): The default is 340,000 mm/s.
•Air Density (RHO): The default is 1.293e-9 kg/mm^3.
•Sampling Frequency: The default is 100 Hz. The Sampling Frequency is used for the scope data.
If the Sampling Frequency is used 1000 Hz, then the sampling time is set with 1.0/1000=0.001 s. Therefore, the computed time interval is defined as the 0.001s for the scope data.
•Patch Set: Selects some patch sets any flexible (FFlex and/or RFlex) bodies.
•Add/Remove: Adds and removes some patch sets.
•Add Row: Adds a row for adding a patch set.
•Delete Row: Deletes a row for remove a patch set.
•Modal ERP: Accesses the Mode Selection dialog box as shown in the below figure. If the selected Patch-Set belongs to the RFlex, the user can select modes to calculate a Modal ERP. The selected modes appliy equally to all Patche-Sets that belong to the same RFlex body
Figure 2 Mode Selection dialog box
•Simulation Time: Selects number of animation frames.
•Start Frame and End Frame: Sets start animation frame and end animation frame with a slider control.
•Time: Shows simulation time each selected the Strat Frame and End Frame.
•Frame: Sets frame number. (A natural number is available.)
•Base Directory: Shows the base directory which has animation data and target directory for generating results files. Acoustics toolkit generates following files.
•*.ACS file: has scope data (raw data).
•*.ERP file: has ERP data (raw data).
•*.ARD file: has a ERP contour data on a flexible body.
•*.AMMX file: has a Min. and Max. ERP data for contour on a flexible body.
The Acoustics result files should exist on the base direction.
•Base Name: Sets result name. The Base Name is a model name.
•Import: If previous calculated Acoustics result exists, then the Acoustics Result List dialog shows available list. The user selects a previous calculated Acoustics result. Note that the user should have previously selected the Patch-Set used at the time of the calculation of the selected result.

•Calculation: Calculates Acoustics results. And the calculated result is imported. If the base name exists in the base directory, then the results are changed with latest parameters.
