From Geometry to Results: A Complete CFD Simulation Workflow From Geometry to Results: A Complete CFD Simulation Workflow Computational Fluid Dynamics (CFD) is a powerful tool used across industries—from optimizing HVAC systems in large facilities[cite: 14] to evaluating building ventilation[cite: 15] and structural dynamics[cite: 1, 2]. However, obtaining accurate and trustworthy simulation results requires following a structured, step-by-step end-to-end workflow[cite: 2, 4]. Whether you are using commercial tools like ANSYS Fluent[cite: 14] or open-source solutions like OpenFOAM[cite: 1, 14] and FDS (Fire Dynamics Simulator)[cite: 1, 15], this guide breaks down the essential stages of a complete CFD simulation workflow: Pre-Processing, Solver Setup, Execution, and Post-Processing . What This Guide Covers Stage 1: CAD Geometry Preparation & Cleanup Stage 2: Mesh Generation & Independence Verification ...
