Meshing Complex Geometry | Virtual Topology, Defeaturing & Pinch Control (ANSYS Meshing)
#VirtualTopology #Defeaturing #PinchControl #AnsysMeshing
🎯 Learn how to mesh complex geometries efficiently in ANSYS Meshing — even when dealing with detailed CAD models from SolidWorks or CATIA 🛠💻
🚀 In this complete step-by-step tutorial, you’ll discover three essential geometry cleanup tools that every CFD engineer must know:
🔹 🧽 Defeaturing → Automatically removes tiny holes, short edges, and unnecessary CAD details.
🔹 🧠 Virtual Topology → Merges multiple faces & edges to simplify boundary condition assignment.
🔹 🧲 Pinch Control → Fixes extra edges and geometric gaps directly in the mesher for perfect grid
📘 What you’ll learn:
✅ How to clean complex CAD models in Ansys
✅ Improve mesh quality while preserving geometry accuracy
✅ Solve common CAD import and meshing issues
✅ Use “Create Pinch Control” for surface cleanup
