Abstract

As ultrasonic testing becomes increasingly widespread, education and simulation in UT becomes increasingly useful. This thesis describes development of two simulations - the first, a Finite Difference Time Domain method that can be deployed to consumer GPUs. This simulation is designed to be user-friendly and provide quick interactivity for pedagogical use, for example, in a classroom or industry training. The second simulation is an anisotropic Elastodynamic Finite Integration Technique implementation, which can be deployed to high performance computers for large-scale parallel simulations. This anisotropic simulation is, to the author’s knowledge, the first open-source implementation of anisotropic EFIT.
