Tecplot cannot read heat flux data from OpenFOAM directly with the OpenFOAM data loader in Tecplot. Below are the steps that I use to read the heat flux data or any other data that is not readable by the OpenFOAM data loader.

1. Open your data in paraview.

2. Export the data from paraview using File>Save Data. This will give you a csv file.

3. Now open the csv file in excel and rearrange the data so that we have variable name in the first row as...

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.

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).

The problem summary:

The 'nixOS has two linker programs ld.bfd and ld.gold. They both are situated in /usr/bin/. The /usr/bin/ld is a link to either. If this...

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, near...
