How to Create Professional Meshes in STAR-CCM+ | Meshing Mastery – Part 7 | Beginner to Advanced

In this video, you begin a complete STAR-CCM+ Meshing Mastery series, designed to take you from fundamental concepts to professional-grade meshing skills used in real CFD projects.

Part 1 focuses on building a strong foundation for meshing in STAR-CCM+, explaining how the meshing workflow works and how to think like an expert before generating any cells.

By the end of this series (Parts 1–10), you will be able to:

Create high-quality polyhedral and prism layer meshes

Control mesh resolution using Automated Mesh, Default Controls, and Custom Controls

Generate meshes suitable for heat transfer, turbulence, and industrial CFD

Avoid common meshing mistakes that lead to poor convergence or inaccurate results

Confidently prepare meshes for professional simulations and commercial projects

In this video (Part 1):

STAR-CCM+ meshing philosophy and workflow

Automated Mesh overview

Core mesh vs boundary-layer mesh

When and why mesh quality matters

How this series will lead to full meshing mastery

This tutorial is practical, step-by-step, and based on real STAR-CCM+ projects, not simplified academic examples.

Who this series is for:

CFD beginners starting with STAR-CCM+

Engineers who want clean, reliable meshes

Students preparing for industry-level simulations

Anyone aiming for true meshing mastery, not trial-and-error

Automated Mesh Operation Overview

We are using the Automated Mesh operation.
This meshing approach consists of three main algorithm groups:

1. Surface Mesher
2. Volume Mesher
3. Boundary Layer Mesher

All meshing algorithms are defined within this single automated operation.

---

Surface Mesher

The first algorithm is the Surface Mesher.

This option is especially useful when:

You import a part into STAR-CCM+ that was already meshed in another software
For example, when importing a surface mesh from ANSYS Fluent

By selecting the Surface Mesher, you allow STAR-CCM+ to:

Re-mesh the imported surface
Rebuild the mesh based on your own parameters

This gives you full control over mesh quality and consistency.

---

Volume Mesher Options

For the volume mesh, we have two main choices:

Polyhedral Mesher
Trimmed Mesher
Tetrahedral Mesher

Each has different characteristics in terms of:

Cell quality
Numerical stability
Computational cost

---

Boundary Layer Mesher Options

For the boundary layer, STAR-CCM+ provides two options:

Prism Layer Mesher
Advanced Layer Mesher

To demonstrate the differences, let’s change the boundary layer method from Prism Layer to Advanced Layer Mesher.

---

Advanced Layer Mesher – Key Behavior

If you look at the image, you will notice that the mesh displayed previously corresponds to prism layers.




After switching to Advanced Layer Mesher and executing the operation, the mesh is regenerated.

What immediately stands out is the transition region between:

Boundary layers
Core volume mesh
