Feasibility of deep-sea mining simulation using Yade

Hi Ziyu,

I would call Yade a multibody dynamics software :)

What effects do you want to include? Does it need to be a coupled simulation? Maybe you can start with a kinematically driven tool made of facets. Next step of complexity would be making a dynamic clump of facets and drive the tool with force controlling function (programmed in Python). Alternatively, one can add such a function in the C++ source code to speed up the simulation.

Cheers,
Karol

Hello,

I would say it is possible.

If it is feasible, it depends on maaaaany factors. Mainly definitions of:
- "deep-sea mining problems", expected results, model and simplification used, .....
- "feasible"
and other factors, like role of water, model spatial and time scale, ...
Also time and other resources available, if an existing material model can be used or a new one needs to be developed (from scratch or just implement)......
Really many many factors.

Depends on definitions of:
- "realize"
- "the simulation"
- "seabed soil particles"

> 2.

Depends on definitions of:
- "the interaction"
- "the seabed mining car"

YADE is actually abbreviation of Yet Another DYNAMIC Engine

> Does Yade include a multi-body dynamics module

It depends on definition of "a multi-body dynamics module".
From certain point of view, Yade itself can be viewed as "a multi-body dynamics module".

> to simulate the tracked motion of the mine car?

what is "the tracked motion"?

> can Yade be coupled with other dynamics software?

Yes (strongly depending on definition of "can").
Just now as it is? With little changes? With significant changes?

Basically it depends on the other software.
Yade uses Python interface, it is possible to couple Yade in the Python layer.
It is also possible to couple Yade in C++.

Hi,Karol and Jan,thanks for your kindly answer!

>Maybe you can start with a kinematically driven tool made of facets. Next step of complexity would be making a dynamic clump of facets and drive the tool with force controlling function

Do you mean to regard the mine car tracks as facet particles for dynamic research?
(track:Wheels of mining car)

>If it is feasible, it depends on maaaaany factors.

Yes,I can understand what you mean.I think the key to my question is whether Yade can realize the simulation of the interaction between the mine car track motion and the soil particles.If so,are there any papers or sample scripts?

>what is "the tracked motion"?
This means the dynamic movement process of the mine car track(the wheels of mining car).

Best wishes!

Yade can realize simulation between rigid body and spherical packing.
Rigid body can be made of facets, boxes, ... more options here

See e.g. bulldozer example [1]. The example is very simple, the bulldozer has prescribed velocity, but in general it can have variable velocity or be dynamic, or be composed of multiple parts, or ...
