Where is Fluent located and how do I access it?

Please note: The FAQ pages at the HPCVL website are continuously being revised. Some pages might pertain to an older configuration of the system. Please let us know if you encounter problems or inaccuracies, and we will correct the entries.

We have two versions of FLuent installed on our systems.

The "legacy" version of Fluent is 6.3. This version is installed to be run on our main production M9000 cluster. Note that this is not a recent versaion of Fluent, but is provided as the last version that is supported on the Solaris/Sparc platform. Note that this version will be de-comissioned in 2014. We recommend to use newer versions if you are just starting off using Fluent. The programs of this Fluent package are located in the directory/opt/fluent/Fluent.Inc/ on sflogin0 and the Solaris nodes.

The most recent version of Fluent is Ansys-14 Fluent. This version is installed to be run under Linux on the "software" (Linux) cluster. It will not work on the Solaris production nodes. The programs of this Fluent package are located in the directory/opt/fluent/ansys-14.0/ on sw0010 and the Linux production nodes.

To use Fluent on any of HPCVL's clusters, you have to be a trained University User of Fluent. It is furthermore required that you read our licensing terms, and sign a statement. We will confirm your statement, and you will then be made a member of a Unix group fluent, which enables you to run the software. Contact us if you are in doubt of whether you qualify to run Fluent on our system.

The Fluent license is "seat limited" and "process limited". At present, there are the following licensing limits on our systems:

  • 25 program runs plus 200 parallel processes on the Solaris platform. This is the "legacy version" 6.3 Fluent. It will be available until June 2014.
  • 25 program runs plus 200 parallel processes on the Linux platform. This is the recent Ansys-14 version of Fluent that is only supported on the Linux platform.

i.e. at most 50 separate sessions can be run simultaneously (serial or parallel). In addition, it is possible to run up to 200 "parallel only" processes in total. One scenario would be 50 users have 5-process parallel jobs running, each with one master (i.e. seat) and 5 slaves (parallel only), thus using up all available Fluent resources.
