Скачать или смотреть How to Mesh Periodic Turbomachinery Geometry in ANSYS Fluent (Poly-Hexcore + Sliding Mesh)

In this tutorial, I generate a high-quality mesh for the previously created compressor blade sector using ANSYS Fluent Meshing (Watertight Geometry Workflow).

We create a Poly-Hexcore mesh with periodic boundary conditions, which significantly reduces the total cell count while maintaining accuracy for turbomachinery simulations.

In this video, you will learn:

How to set up periodic boundary conditions in Fluent Meshing

How to correctly assign boundary types for turbomachinery CFD

How to prepare the mesh for Sliding Mesh simulations

Why we should NOT use Share Topology when rotating and stationary zones are present

How to define four non-conformal interfaces between rotating and stationary domains

To properly apply the sliding mesh approach, interfaces must exist between rotating and stationary zones. For this reason, topology sharing is avoided, and non-conformal interface mapping is defined between the zones.

This workflow is essential for simulations involving rotating machinery, compressor stages, and sector-based periodic modeling.

If you're working on turbomachinery CFD and want a structured, efficient meshing strategy — this tutorial will help you avoid common mistakes and reduce computational cost.
