If you’re looking to download and install OpenFOAM on Windows 11, you’ve come to the right place. OpenFOAM is one of the most powerful open-source CFD tools available today, but beginners often face difficulties setting it up on Windows.

In this guide, I’ll walk you through:

• ✅ The difference between OpenFOAM Foundation (org) and ESI-OpenCFD (esi) versions.
• ✅ Step-by-step installation on Windows 11.

1. Which OpenFOAM Version Should You Download?

There are two main distributions of OpenFOAM:

  • Community-driven, academic focus.
  • Frequent updates, widely used in universities.
• ESI-OpenCFD (openfoam.com)
  • Industry-oriented version by ESI Group.
  • More stable for production environments.

👉 Both versions work on Windows 11 — so it depends on whether you want an academic or industry flavor.
