How to Create Professional Meshes in STAR-CCM+ | Meshing Mastery – Part 2 | 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

Part 2 – Geometry Creation and Sketch Constraints

In the previous part, we explained that our goal is to evaluate the quality and characteristics of the volume mesh generated around two fins. The first step in doing that is to create the geometry of the problem. As I mentioned earlier, I want to start by working with a sketch inside the 3D-CAD environment.

For this, select the XY plane. In the Features tree, right-click on the XY plane and choose Create Sketch so that we can start drawing our sketch.

As I said, I want to proceed point by point. This is a very simple and effective approach, especially if you want full control over the geometry. You can also directly create lines using the Line tool, which is the option currently active in the toolbar. Click on it, and then start defining the geometry by drawing lines.

At this stage, I am not concerned with exact dimensions yet. I will draw a rough, approximate shape first. Later, we will use constraints to properly define and control the geometry. This is actually a very good exercise to understand how constraints work and how they affect the sketch.

Now I have drawn the overall geometry and created the basic sketch. The next step is to apply constraints.

The first constraint I want to apply is to ensure that these edges all have the same length. To do that, I need to select multiple lines at the same time. Click on the first line, then hold Ctrl and select the other lines.
