Hello REEF 3D team,

I have a few queries,
1. How to implement ghost cell method in REEF 3D model? Is it X 13 ?
2. How to incorporate the relaxation coefficient (Kr)? Please look into the file i have attached.
3. How to implement the k-omega SST model? Is it T 10 22?

I am also waiting for the query that I have posted previously. if possible could you please look into that because I am facing the same issue again and again.

Thank you

1. The ghost cell method is already implemented in REEF3D is the primary method for REEF3D to manage all the solid-fluid boundaries.

2. I need more context for this, I have never seen this before

3. REEF3D does not have the SST model. T 10 22 is k-w for URANS while T 10 2 is k-w for RANS. T 10 2 includes limiters that are sufficient for wave simulations.
T 36 introduces a free surface turbulence boundary condition as described in this paper

Hello Kamath,
Thanks for response

https://doi.org/10.1080/19942060.2018.1438924
In this paper, the author mentions the relaxation coefficient (kr) (equation no. 16) also, in Paragraph no. 2.2.1.1, he mentions that he used the k-omega SST model in REEF 3D.

If possible, can you please review this paper and clarify my doubt?

Thanks

The equations they show correspond to T 10 2, but there is no SST there.

With regards to the Kr coefficient, get in touch with the corresponding author of that paper as I am not aware of the changes they might have made to the source code for their work. It is not implemented in the official REEF3D releases
