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.

Error Compiling OpenFOAM .. Linker Error ld "--add-needed is not supported"

Posted October 21, 2013 at 15:44 by Hisham (Notes for OpenFOAM!)

If an error occurs while compiling OpenFOAM from source that has to do with the "linker" ld does not support the --add-nedded option (Read more at: http://www.openfoam.org/mantisbt/view.php?id=685 and http://www.cfd-online.com/Forums/ope...roblem-ld.html).

These are the implementations of two static SGS models, due to Vreman and Nicoud (see the attached files for the detailed references). These models are in the same spirit of the well known WALE model; still, they are different in several aspects.

The models are provided without any kind of warranty; still, no specific problem came up during testing.

For wall bounded turbulent flows in Fluent i strongly suggest the Vreman model due to its specific, theoretically wrong,...

Result line fit really good.
And it's much more better than 2D calculations of the same airfoil
