Submarine Scattering: Time-Domain Simulation and FFT
Application ID: 55921
This model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. Then, a Time to Frequency FFT study is used to transform the results into the frequency domain and the scattered field is analyzed with the Exterior Field Calculation feature.
This model example illustrates applications of this type that would nominally be built using the following products:Acoustics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
