CFX or Fluent for Turbo machinery ?

Posted May 27, 2011 at 03:03 by Far

First I would like to say that both flow solvers tend to provide the similar results if the mesh is of good quality and has appropriate no.of nodes and yplus values.

Therfore the first and the most important rule is to make, in any simulation of turbo machinery in particular and external flows in general, high quality mesh with all appropriate parameters e.g. yplus.

Now lets come to the difference

1. CFX has good turbulence models, although after merger...

Building Code Documentation on OpenFOAM 2.0.0/x

Posted June 24, 2011 at 18:06 by wyldckat
Updated August 30, 2014 at 08:18 by wyldckat (A note about Ubuntu 10.10 and above)

For now, these are only instructions for Ubuntu (11.04 to be exact, but they should work for 10.04 and above), and it shouldn't be all that different for OpenSuSE.

Note: I've discovered the other day, thanks to a fellow user of this forum, that Doxygen 1.7.1 on Ubuntu 10.10 does not build the code documentation for OpenFOAM 2.0. Nonetheless, a solution is already known (two actually) and is shown here:

Building OpenFOAM 2.0.1 on old Linux OSes - test case Ubuntu 8.04

Posted October 17, 2011 at 17:49 by wyldckat
Updated February 8, 2012 at 17:41 by wyldckat

This blog post will try to detail and complement the OpenFOAM 2.0.1 building process on old machines, where my test case was with two Ubuntu 8.04 - one i686 and one x86_64 - in two separate virtual machines with 1.6GiB of RAM and 4 processors each.

This post will detail a lot more information than the official instructions, specially because the official instructions are meant for Linux OSes that are modern'ish, such as Ubuntu 10.04 and above.

NOTE: 2011-02-08 - finally...

Getting ANSYS 14 Fluent, Windows 8.1 and VS2013 to compile UDFs

Posted October 27, 2013 at 18:00 by trollreign

1. Goal

I am a beginner at Fluent, and even more so concerning UDF's. I am facing a problem where I have to use a velocity profile at my inlet boundary and later I would like to write code to model an actuator disk. After reading the corresponding sections of the Fluent 14 UDF Manual I felt like I am ready to face the task.

Things didn't go half as smooth as I expected and in the end I spent a weekend getting it to work.
