Questions of model refinement and FLOW-WAVE coupling

Youngling Post: 1 Join Date: 9/6/12 Recent Posts
I am new to delft-3D and I am starting a project that needs FLOW and WAVE coupling.
The DEM has 3 level of refinements (coarse, medium and fine). The finer grids are totally inside the coarser grids.
My questions are:

1. Should I use domain-decomposition or nesting to achieve the model refinement?

2. One wave model could only couple one FLOW model. I heard domain-decomposition could not be used for WAVE. Then if I choose domain-decomposition for FLOW, should I build several corresponding WAVE models as well? If I use nesting, the grid for WAVE should be the same as FLOW or not?

3. How about the DEM inconsistency between each level of refinement?

Hi You Yao,

 

Did you receive a reply, or find the answers to your questions. I'm looking for similar answers!

I want to have a coarse and fine grid of my study area, but am unsure whether the FLOW or WAVE model should have coarse-fine nesting and if wave, whether the finest resolution needs to be the same as the FLOW.

 

Thanks

Chloe
