An open-source GPU-accelerated application of the elastodynamic finite integration technique (EFIT) to three-dimensional wave propagation and scattering in anisotropic materials of arbitrary geometries

As ultrasonic testing (UT) becomes increasingly widespread, accurate numerical simulations of the complex wave propagation behavior in solids become increasingly useful. This is especially true for complex geometries and material properties created by new manufacturing processes such as those use to create Additively Manufactured Metals (AMMs). Here, we present an open-source fully-anisotropic Elastodynamic Finite Integration (EFIT) implementation written in the Julia language which can be deployed to high-performance computers for large-scale parallel simulations. Results of benchmarks against existing isotropic implementations, published data, and collected measurements will be presented.
