AQWA is an underwater acoustic software that can be used to solve hydrodynamic and hydroacoustic problems for a variety of ships and ocean structures. In AQWA, the Far-field method is used to calculate the acoustic scattering of structures. Next, I will briefly introduce how to set up far-field method in AQWA for solving.

1. Create the model
First, create your structure model in AQWA. You can use AQWA's modeling tools to create structures, or you can import models created in other CAD tools.

2, Define the calculation area
In AQWA, you need to define the calculation area, that is, the water around the structure. In AQWA's "Calculation Settings" window, you can set the size and shape of the calculation area, as well as water depth and wave conditions, among other things.

3, select solver
In AQWA, you can choose two kinds of solver: the time domain solver and the frequency domain solver. If you choose the frequency domain solver, you can select the far field method in the Advanced Settings window to perform the calculation.

4, Set the far field method
In the "Advanced Settings" window of AQWA, you need to select the "far field method" option. In the setting of the far field method, you can choose to calculate the far field sound pressure or the far field scattering coefficient of the model, and also set the calculation range and resolution of the far field.

5. Run the calculation
With the far-field method set up, you can run the calculation. After the calculation is complete, you can view the results and post-process the results, such as plotting the sound pressure or scattering coefficient, etc.

It should be noted that the far field method needs to consider the size and shape of the structure and other factors in the calculation, so it requires certain computing resources and time. When using the far-field method, set it according to your computing resources and time requirements to get accurate results.

the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > in AQWA, Far Field Method(Far Field Method) can be used to calculate structure produced in the Far away from the source point of free surface of the waves. If you want to use the far-field method, you need to set the following:

  1. Select the "Program Control" option under the "Define Analysis" menu in AQWA.
  2. In the Program Control window, select the Far Field Method option.
  3. Under "Far Field Method" option, you can set the corresponding parameters, such as calculation range, resolution, maximum frequency, etc. The setting of these parameters will directly affect the accuracy and speed of calculation.
  4. Click the "OK" button and then select "Yes" to confirm that the far-field method is used.

Note that the far field method requires higher computational resources and time, due to the larger calculation range and higher resolution. In addition, when using the far field method, the distance between the structure and the free surface needs to be considered to ensure the accuracy of the calculation results.
