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, that is, 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, so that the probing wave resembles a plane wave. In such cases, including the source would require a 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 how to use the obtained solution as the known incident field for a subsequent study solving the scattering problem.
