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.

All about the PIMPLE algorithm - Part II

Posted October 21, 2014 at 17:55 by Tobi
Updated September 28, 2016 at 05:04 by Tobi (Some errors and mistakes)

## Case 3.1 ##

Now we will use the following fvSolution file:
Code:
PIMPLE
{
    nCorrectors            1;
    nOuterCorrectors    2;
}
Compared to Case 2 there is not a big difference. The only difference is that we calculate the pressure - momentum coupling in one time step twice:
  1. Calculate momentum
  2. Calculate pressure
  3. Recalculate momentum from new pressure
  4. Recalculate pressure from new momentum
Calculation in OpenFOAM is like:...

OpenFOAM: Interesting cases of bad meshes and bad initial conditions

Posted September 15, 2013 at 06:03 by wyldckat

This year (2013) has been an interesting one for me, regarding OpenFOAM. Even beyond the amazing features that OpenFOAM 2.2 brought to the world (at least to my world) and everything that I keep discovering about it.

This blog post is about the various threads/posts were I took the time to diagnose what was specifically wrong with the case and where the bad results are astonishingly wrong... simply because the details were not easily seen. The list might get updated along time, as I...
