Steady-State and Transient Wake Capturing through Mesh Adaption

This Application Best Practice focuses on using adaptive mesh refinement (AMR) in Ansys Fluent® fluid simulation software to accurately capture steady-state and transient wake phenomena in fluid dynamics simulations. It provides guidance on how to apply mesh adaptation techniques to improve solution accuracy and efficiency, especially in regions with complex flow features like wakes, vortices, and shear layers.

Learning Outcomes:

After completing this course, participants will be able to:

1. Understand the principles and benefits of mesh adaption for steady-state and transient wake-capturing simulations.
2. Create and configure cell registers using turbulence and flow-field variables for adaptive mesh refinement.
3. Set up and control steady-state and transient mesh adaption workflows in Ansys Fluent.
4. Monitor mesh quality, cell count evolution, and solution convergence during adaptive simulations.
5. Evaluate wake structures, aerodynamic forces, and flow-field predictions using adapted meshes for improved simulation accuracy.

Please note: These training materials were developed and tested in the 2022R2 release.
