    Status: Open => Needs information

Jan Stránský requested more information:
Hello,

thanks for some info (although it is still very general).

> ocean structure

What kind of structure?
Some massive, possible to simulate as a rigid body?
Or some not so stiff/strong and also the structure would need actual simulation (deformation, collapse)?

> the fracture process of sea ice in engineering scale

What is "engineering scale"?


Why do you want to use DEM and not e.g. FEM or some of its derivatives (XFEM)?

I **personally** see the advantage of DEM for the scenarios, where you have massive fragmentation / crushing and the products of crushing influences significantly the further process.
For the case of ice, I would expect cracking and splitting of the ice into a few pieces, which do not significantly influence each other.
Do you have some experimental results or references?

What is / do you expect the typical "mode" of fracture?
E.g. local ice crushing due to local pressures of the ocean structure, splitting an iceberg into a few smaller icebrgs, ...


How would you simulate water?


Of course, ice breaking can be somehow modeled by DEM or DEM-like method(s), just some brainstorming..

Cheers
Jan
