Hands-On CFD Analysis Using Open-Source Tools

Hands-On CFD Analysis Using Open-Source Tools free download

Accelerate Your Research Workflow by Integrating FreeCAD, Gmsh, OpenFOAM, ParaView, and Cloud Computing

This course provides a practical introduction to a complete open-source simulation workflow designed to empower researchers and engineers in computational modeling and analysis. Participants will learn how to use FreeCAD for creating detailed, parametric 3D models; Gmsh for generating high-quality, customizable meshes essential for accurate simulations; OpenFOAM for setting up and executing a basic computational fluid dynamics (CFD) simulation; and ParaView for visualizing, analyzing, and interpreting simulation results. Rather than focusing in-depth on any single tool, the purpose of this course is to provide a broad overview of an integrated workflow, demonstrating how these tools can be combined effectively from start to finish. As a practical example, we will perform a CFD simulation of flow past a cube entirely from scratch — starting with CAD modeling in FreeCAD, then mesh generation with Gmsh, followed by solving the flow problem in OpenFOAM. Additionally, we will introduce Docker to facilitate reproducible installation and deployment of OpenFOAM on remote servers or different computing environments, ensuring portability and ease of use. Finally, participants will visualize the results in ParaView and perform fundamental engineering analyses such as lift and drag computations. Through a mix of lectures and guided exercises, students will develop foundational skills in CFD workflow management and reproducibility, preparing them to tackle real-world engineering and scientific challenges efficiently. This course is ideal for graduate students, researchers, and professionals across STEM disciplines seeking to integrate powerful open-source simulation tools with modern cloud and container technologies to accelerate their research.
