Description

This course contains the use of artificial intelligence.

If you are new to STAR-CCM+ and want a clear, practical path into CFD—this course is built for you. In this beginner-focused training, you will learn the complete STAR-CCM+ workflow step-by-step: from understanding the interface and creating simple geometries, to building regions, generating meshes, setting up physics, running solvers, and finally post-processing results in a professional way. The course is designed to remove the typical confusion beginners face and replace it with a structured process you can repeat confidently for your own projects.

- Learn boundary-layer meshing fundamentals and quality drivers
- Compare different meshing approaches and identify common pitfalls
- Detect and remove low-quality cells to improve robustness and accuracy

Why this course is different

This course is not just a collection of tool explanations. It is a workflow-first course:

You learn STAR-CCM+ the way engineers actually use it in real projects
You practice correct surface naming, region creation, solver setup, and post-processing
You learn how to judge mesh quality and convergence, not just how to click “Run”
Every topic connects to what you will do next—so you always know why you’re doing something

Who this course is for

Absolute beginners who want to learn STAR-CCM+ from scratch
Engineering students preparing for CFD projects, assignments, or thesis work
New engineers and interns who need practical STAR-CCM+ skills quickly
Anyone moving to STAR-CCM+ from another CFD tool and wanting a structured foundation

Prerequisites

No prior CFD or STAR-CCM+ experience is required. You only need:

A PC/laptop capable of running STAR-CCM+
STAR-CCM+ installed (student/academic/company license)
Basic computer skills

By the end of this course, you will be able to set up your own beginner CFD simulations in STAR-CCM+ with confidence—and you’ll have a repeatable workflow you can apply to more advanced cases later.

Who this course is for:

Absolute beginners who want to learn STAR-CCM+ from scratch with a clear, step-by-step workflow.
Engineering students (mechanical, aerospace, automotive, energy, etc.) who need practical CFD skills for coursework, projects, or thesis work.
New engineers and interns who want to become productive quickly in STAR-CCM+—from geometry and meshing to running simulations and reviewing results.
