Numerical Methods for Chemical Engineers: 2D Lattice Vibrations

Chemical engineering and materials science often require analyzing complex molecular structures at the atomic level. Understanding how two-dimensional lattices vibrate is key to predicting thermal and mechanical properties. This text-based course guides you through the foundational math and programming concepts needed to solve these physical systems numerically. You will start by mastering the essential physics of lattice dynamics, learning how to set up governing equations of motion, and translating these physical laws into robust matrix formulations. What you'll learn: Understand the core principles of 2D lattice dynamics and molecular vibrations; Configure mass-spring systems into governing differential equations; Formulate system matrices and apply eigenvalue analysis to find vibrational modes; Implement modern numerical solvers and write clean, readable code with proper type hints; Analyze computational results to determine stable and unstable physical states. The course begins with foundational definitions of lattice structures and matrix algebra before moving into system setup, numerical solver implementation, and analysis of vibrational modes. This course is designed for chemistry, physics, and chemical engineering students new to computational modeling, with no advanced prerequisites required.
