RE: DFlow-FM Bathymetry exported from Delft3D-Flow model

Combination View Flat View Tree View

Hi all!

I am converting a D3D-Flow model into a DFlow-FM model and I was wondering about the following:

I exported a samples file (*.xyz) from the original D3D-Flow depth file (*.dep) using Quickin and used the samples file as input bathymetry in DFlow-FM (all in cell centres).

Right now I am comparing the results and the initial bathymetry of both models appears slightly different (+/- 1-2 cm).

I am wondering what may cause these differences. Anyone who knows more about this?

Kind regards,

Dear Roy,

As you are likely aware, the interpolation can be influenced by the difference in your grid/network between Delft3D Flow and Delft3D Flexible Mesh. Additionally, the sample set selection and location of samples versus the selected interpolation method can also have an impact. I presume between sample files and depth file you had no differences.

Could you please let me know which version of Delft3D Flexible Mesh are you using?

Kind regards,
