How to Create Multizone Structured Mesh in Ansys ICEM CFD – Simplified Guide

In this tutorial, learn how to create a high-quality multizone structured mesh using Ansys ICEM CFD in the easiest way possible. This video covers: 1- Geometry generation: I demonstrate how to create the geometry of a tube, including fluid and tube thickness domains. Surfaces are assigned meaningful names to serve as boundary conditions in the solver. 2- Blocking: The block is created, and associated with edge parameters, and the number of nodes along each edge is specified. 3- Multizone approach: A new block is assigned for the solid thickness of the tube and assigned a separate name. Interfaces between the two zones are carefully considered. 4- Mesh extraction: Pre-mesh is shown before extracting the mesh for Fluent. 5- Quality checks: Mesh quality is evaluated, and verification of the multizone mesh is performed in Fluent, ensuring thermally coupled interfaces are properly generated. This video offers a detailed and beginner-friendly walkthrough of creating structured meshes for coupled thermal simulations. Please subscribe to our YouTube channel for more videos and support us.
