Elastic Waves, Time Explicit
The Elastic Waves, Time Explicit is used to compute the velocity and strain field in solids with propagating linear elastic waves. In the Add Physics dialog, it is found in the Acoustics branch, under Elastic Waves.
In general, the interface is suited for modeling the propagation of waves over large distances relative to the wavelength, for example, ultrasound propagation for nondestructive testing (NDT), or seismic waves. The interface exists in 2D (generalized plane strain) and 3D.
The interface is based on the discontinuous Galerkin (dG or dG-FEM) method and uses a time explicit solver. The method is very memory efficient and can solve problems with many million degrees of freedom (DOFs). The method is also well suited for distributed computing on clusters.
