Where can I get further help with Fluent?

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.

Fluent is a complex software package, and requires some practice to be used efficiently. In this FAQ we can not explain it use in any detail.

Online documentation for the programs is available on machines where Fluent is installed. On the HPCVL login node, it can be accessed through a webbrowser by typing:

firefox /opt/fluent/Fluent.Inc/help/index.htm

This should give you an index screen to the html version of the docs. You can also use the pdf documentation in


if you prefer a printable version. To look at specific pdf files, you can use acroread, for instance

acroread /opt/fluent/Fluent.Inc/help/pdf/ug/chp01.pdf

shows Chapter 1 of the User's Guide. Unfortunately, the pdf documentation is somewhat unsystematic and one has to guess from the name of the directories (e.g. "ug" for "User's Guide") what they mean.

The documetnation for Ansys-14 Fluent can be access from inside the program GUI by clicking on the "Help" button on the upper right. This is in html format. The pdf version of the docs can be found in 


Fluent documentation is subject to the same license terms as the software itself, i.e. you have to be signed up as a Fluent user in order to access it.

If you are experiencing trouble running a batch command script, check carefully if the sequence of commands is exactly in sync with the program. This might mean typing them in interactively as a test. If you have problems with the GridEngine, read our FAQ on that subject, and maybe consult the manual for that software which is accessible as a PDF file. HPCVL also provide user support in the case of technical problems.
