High-quality meshes are the foundation of accurate, stable, and efficient CFD simulations. This course provides a practical, hands-on introduction to CFD mesh generation using widely adopted open-source tools within the OpenFOAM ecosystem. Instead of focusing on theory alone, the course emphasizes real meshing workflows, common pitfalls, and best practices that directly impact solver performance and numerical stability.You will learn how to generate both structured and unstructured meshes using tools such as blockMesh, Classyblocks, snappyHexMesh, cfMesh, and Gmsh. Through carefully designed 2D examples, the course demonstrates how different meshing strategies influence solution accuracy, convergence behavior, and computational cost. These simplified cases allow you to focus on meshing fundamentals while still reflecting real CFD challenges.The course combines video lectures, additional reading material, and ready-to-run case files, enabling you to follow along and experiment independently. You will explore techniques for geometry preparation, surface refinement, boundary layer generation, and mesh quality assessment using standard CFD metrics. Each topic is reinforced with practical examples that highlight how poor meshing choices can lead to instability and how to fix them effectively.By the end of the course, you will be able to confidently select and apply the right meshing tool and strategy for a given CFD problem, build reproducible preprocessing workflows, and generate meshes that lead to reliable and efficient OpenFOAM simulations. This course is ideal for students, researchers, and professionals who want to strengthen their meshing skills using fully open-source CFD tools.

This course offers a thorough and practical introduction to SolidWorks, a popular 3D CAD software used in mechanical design, engineering, and product development. It is great for students, engineers, and technical professionals who wish to improve their modeling skills and use them in real-world applications.The course begins with the fundamentals of sketching and feature-based part modeling, then progresses to more sophisticated techniques. Participants will learn how to use parametric design principles to generate precise 3D models, establish feature connections, and efficiently use dimensions and apply materials. The instruction then moves to the assembly environment, where students will learn how to construct whole mechanical systems by joining different components in the right alignment, interaction and applying the required mates.Specialized design tools such as weldments and sheet metal will be provided, allowing students to precisely develop structural frameworks and folded sheet components. The course also offers an introduction to SolidWorks Simulation, which allows students to do basic structural analysis to evaluate and enhance the strength and performance of designs under load.By the completion of the course, students will be able to create and assess precise mechanical designs, comfortably navigate the SolidWorks interface, and use best practices for efficient and professional 3D modeling.
