OpenFOAM Wind Around Buildings Tutorial | CFD Simulation Step-by-Step | CFD Simplified

In this tutorial, we explore the windAroundBuildings case in OpenFOAM, where we simulate how wind flows around buildings in an urban environment. This type of CFD simulation is widely used in urban planning, pedestrian comfort studies, environmental analysis, and HVAC design, making it highly relevant for real-world engineering applications. In this video, we go step by step through the complete workflow — from case setup and mesh generation to running the simulation in parallel and visualizing airflow patterns around the buildings. 🔍 What you’ll learn in this video: Understanding the building geometry and domain Mesh generation using blockMesh Case setup and boundary conditions Running simulation using simpleFoam Parallel execution using mpirun Post-processing and flow visualization 🎯 Who is this for? CFD beginners OpenFOAM users Engineering students and professionals Anyone interested in urban airflow simulation 💡 Why this case is important: The wind around buildings simulation helps you understand real-life airflow behavior in urban environments, which is essential for designing safer and more efficient spaces. 📢 Don’t forget to: 👍 Like the video 💬 Comment your questions or suggestions 🔔 Subscribe to CFD Simplified for more practical CFD tutorials #CFD #OpenFOAM #UrbanFlow #WindSimulation #CFDTutorial #Engineering #Simulation #HVAC
