This chapter investigates the ability of ChatGPT to generate code in the field of Computational Materials Science, specifically using GPT-4. The focus of this study is on solving the wave equation in 2D, considering elastic wave propagation, and visualizing the results using Python with a finite difference time domain (FDTD) scheme. The wave equation is fundamental in understanding how waves, such as sound or seismic waves, travel through different media. The FDTD method is a numerical technique used to model wave propagation by discretizing both time and space. This involves setting up a computational grid, applying initial and boundary conditions, and iteratively solving the wave equation to simulate the wave’s behavior over time. Visualization of the results helps in interpreting the physical phenomena and verifying the accuracy of the computational model.
