Implementation of Coherent Structure sgs Model for LES

Lorenzo92 · January 12, 2020, 06:13

Hello everybody,

I wanted to ask you if anyone among you, more advanced users, have never implemented the Coherent Structure Model for LES in OpenFoam (version >= 4.0) ?
The model has been developed by Kobayashi (The subgrid-scale models based on coherent structures for rotating homogeneous turbulence and turbulent channel flow , 2005) .
I would definetely be grateful if someone could post a template of source files if available of course, so as to have a starting template to work on, since this would be my first serious implementation of a new sgs model in Foam.

Thank you very much in advance

Lorenzo

I think I did it

Hello Lorenzo,

I am implementing the Sigma SGS model by Nicoud (2011) . I think I have the code correctly implemented but I still get errors while complining. The errors are probably in how I set up my Make files. Did you hapen to find a template or reference guide for how the implementation is correctly carried out in OpenFOAM?

I am using openFOAM 7. Would appreciate your feed back.

Thank You,
Farouk

Dear Lorenzo,
It's been a long time, but I'd like to ask if you implemented the Sigma SGS model and tested well. If possible, whether I can get the source code, I am very interested in testing this model.
