The remainder of this note gives you some information about the V2009.4 software release. Please read on to learn more about the updates and let us know if you have any comments or questions.

IMPORTANT NOTE: If you are running V2008.x or earlier software versions, then you may require a new license to run V2009.x versions! If you are currently running V2009.0 or V2009.2, then you will NOT need a new license to run V2009.4. ESI licensing policy requires licensing to the version of the software. This means that if you currently have a V2008.x (or earlier) license file, you will need to replace it with a V2009.x license file. These are available upon request from your ESI license or sales representative. If you are not sure who that is, you should contact This e-mail address is being protected from spam bots, you need JavaScript enabled to view it . Please include your existing V2008.x license file for the quickest service.

V2009.4 Installation

The V2009.4 software will be installed parallel to your existing V2009.2 (or earlier) installation. This means that you will have access to all versions should you desire. However, only V2009.4 will be supported going forward, so you should use V2009.4 to get access to future software issue resolutions and feature improvements. Step-by-step instructions for the download and installation of V2009.4 software can be found in the Getting Started Guide (located in the Knowledge Base section of the ESI CFD Portal - login required).
