Hi,

at our institute we did some modifications in fluent for the standard k-epsilon model via 'user defined functions'.
The simplest ones were just to modify the source terms.
Doing those modifications should be pretty easy in OpenFoam too; at least I expect that for an opensource code.

Now, I took a look at the files in
OpenFOAM-1.1/src/turbulenceModels/incompressible/kEpsilon
there are two sections for the dissipation and kinetic energy eqn.
Is this the only place I should care when adjusting the model or are there more to look at?
Then a Allwmake for the source should do the job to integrate the new code!?

Best Greetings!

You are right. All the code sp
 
You are right. All the code specific to the incompressible k-epsilon is in that directory.

Better even would be to create a copy of those files and rename them (and the class inside them). Make sure you change the TypeName in the .H file as well. Compile them (change Make/files) and you'll have your own turbulence model.

Hi Mattijs, thanks! That so
 
Hi Mattijs,

thanks! That sounds great!
I think that helps to convince my Prof. using it :-)

Greetings!
