This guide presents a structured methodology for post-processing computational fluid dynamics (CFD) simulation data from ANSYS Fluent using MATLAB. It provides step-by-step procedures for data extraction, file organization, and efficient handling of large datasets through memory-mapped techniques and parallel processing. The document demonstrates key post-processing tasks including contour visualization, spectral analysis, gradient computation, streamline and particle visualization, and video generation for transient flow analysis. Emphasis is placed on reproducible workflows, scientific plotting standards, and practical implementation strategies suitable for both beginners and advanced users. The guide ultimately enables accurate qualitative and quantitative interpretation of flow physics for research and engineering applications.
