OpenFOAM Foundations: Practical Numerical Modeling for Fluid Mechanics

Numerical modeling is a critical skill for modern engineers, yet getting started with powerful command-line simulation tools can feel intimidating. This written course breaks down OpenFOAM from the ground up, helping you confidently set up and run your first fluid simulations. By working through structured text explanations and step-by-step case configurations, you will transition from a complete beginner to a practitioner capable of preparing, executing, and troubleshooting basic fluid dynamics simulations. You will also learn how to leverage modern containerized environments to ensure your simulation setups are reproducible and portable. What you'll learn: - Understand the core architecture and directory structure of an OpenFOAM case - Configure boundary conditions and physical properties for classic fluid dynamics problems - Generate and refine numerical meshes using built-in utility tools - Run solvers and monitor simulation convergence through text-based logs - Analyze simulation results using modern open-source post-processing workflows - Apply containerization basics to run OpenFOAM consistently across different operating systems The course begins with foundational concepts of computational fluid dynamics and the OpenFOAM environment, before guiding you through the step-by-step setup and execution of classic fluid mechanics cases. This course is designed for engineering students, researchers, and professionals new to computational fluid dynamics, with no prior OpenFOAM experience required.
