Scattered-Field Formulation for Elastic Waves

Application ID: 115741

This model showcases how to solve for the scattered field when knowing the incident field for three different types of scatterer, i.e. an infinitely rigid one, a cavity and an elastic inclusion.

This formulation can be useful when the scatterer is in the far-field of the source, such that the probing wave resembles a plane wave. In this case, including the source would require an unnecessarily huge computational domain to be meshed. Both P and S plane waves are thus used as incident fields in the model.

Moreover, the model shows how to numerically compute the field emitted by a point source, and then use such solution as the known incident field for a subsequent study where the scattering problem is solved.

This model example illustrates applications of this type that would nominally be built using the following products:
