Technical Guide to the CFD Process: From problem definition to results validation

This book provides a structured and practical guide to the complete Computational Fluid Dynamics (CFD) simulation process, from the initial understanding of the physical problem to the verification, validation, and communication of results through a technical report. Rather than focusing on the use of a specific software package, the book emphasizes engineering judgment, physical reasoning, and good practices that are essential for obtaining reliable and defensible CFD results.Throughout the chapters, the reader is guided step by step through each stage of a CFD study: problem definition, computational domain selection, geometry preparation, mesh generation, solver configuration, simulation execution, result visualization, analysis, validation, and reporting. Common mistakes, real-world lessons learned, and practical recommendations are presented to highlight how incorrect decisions at any stage can compromise the entire simulation, even when numerical convergence is achieved.This book is intended for engineering students, researchers, and practicing engineers who want to strengthen their understanding of CFD as an engineering process rather than a black-box tool. It is especially useful for those seeking to apply CFD responsibly in academic, industrial, or consulting environments, where results must be physically consistent, well justified, and clearly communicated.
