vertical layers

Youngling Posts: 5 Join Date: 10/19/20 Recent Posts
Hey guys,I'm new in Delft3D-FM for my studies at university. I'm simulating some waves and flow through the wind in a lake. So I should put vertical layers to get more realistic values for sediment at the bottom and flow from the wind at the water surface. Therefore I want to use the "sigma"-layering. In Delft3d it was possible to define every single layer with a different percentage, in FM it's only linear sectioning e.g. 10 layers á 10%). Is it somehow possible to change that?
I cannot find any information in the manual. Only something that can be done through the MDU file. But how do I get the non-uniformly distributed layer thickness?
FLOW_FM Manual 1.5.0 (12/2019) page 54.Thanks for the help!!

Please use a more recent version of the D-Flow Flexible Mesh user manual. Then, in Chapter 10 ( "3D Modelling") you can find how to specify layer thicknesses. See keyword StretchCoef.
