Add new RASModel kEpsilon modification

ivanwhlau · August 20, 2008, 05:35

Hello,

I am interested in making kEpsilon with Launder-Kato modification or MMK. Or, K-epsilon-phi model.
How can I create my own RASModel? Or, is any of these models above available?
I have already copied kEpsilon folder and made changes insides 'src' folder for LK and MMK. But, i am not sure what to do next?
I changed turbFoam before. But, changing RASModel is not as straightforward.
Please kindly advise.

Thanks in advance,
Ivan

Hi Ivan,
If you made changes under OpenFOAM-1.5/src/turbulenceModels/RAS/incompressible, you usually can add your .C file to Make/files and run wmake libso under the directory.

By the way is there any chance that we can share your code?

Hi, Takuya,

Thanks for your advice.

The code are complied and "working" now, but I am not sure if the result is correct at this moment.

In term of sharing, the works are the properties of university. Therefore, I can't post it here.
However, do you have those research papers? (Let me if you don't) It is actually quite easy to modify, and it should not take too long. I am more than happy to assist you in regards to this modification.

Regards,
iL

Hi Ivan,
Thanks for your kind offer. That's no problem, I have some literature about them and believe their implementations will not be so difficult. Just I was too lazy to code and validate them by myself
