How to Get Helicity & Q-Criterion in ANSYS CFD Post-Processing | Visualizing Turbulence

In this ANSYS CFD-Post tutorial, we go beyond basic velocity vectors and pressure contours to visualize the true rotational mechanics of turbulent flow. Learn how to accurately extract and plot the Q-Criterion and Helicity to find true vortex cores and track swirling fluid motion. Whether you are analyzing aerodynamics, pipe flow, or mixing tanks, these two parameters are essential for understanding complex fluid dynamics. 📌 What you will learn in this video: • How to set up domain transparency for better internal flow visibility. • How to create a Q-Criterion Isosurface to isolate the solid core of a vortex. • How to map Helicity on a contour plane to track right-handed and left-handed spiral motion. • The physical meaning behind both parameters explained in simple, practical terms. 💡 Quick Concept Recap: • Q-Criterion: Strips away the sliding/shearing motion of the fluid to highlight only the areas where the fluid is genuinely spinning in a circle. • Helicity: Measures the "corkscrew" nature of the flow, pinpointing exactly where the fluid is moving forward and twisting at the same time. 👍 If you found this tutorial helpful, please leave a LIKE and let me know in the comments what fluid dynamics parameters you want me to cover next! 🔔 Subscribe to ANSYS Tutor for more step-by-step engineering simulation guides! #ANSYS #CFDTutorial #FluidDynamics #EngineeringSimulation #ANSYSFluent #CFDPost #Aerodynamics #Vortex Join this channel to get access to perks:    / @ansystutor
