displacement

Asked by 403175147 on 2013-11-28

Hi
       I would like to use the manifold cover concept of the numerical manifold method in YADE, So I want to know the particle displacement function source code. It is that displacement function is the function used to represent the particle movement. Which is the source of displacement function of particle motion in yade? What information do I need to learn?

Hi,

I am not sure, that my answer will be useful. Please, have a look at
newtonintegrator [1]. Maybe it will give you some ideas.

Hi,

I just discovered this manifold numerical method you spoke about. It seemed to me as having, at least some, common features with FEM. So, I do not know if it would be possible for you to use it with Yade.
In Yade, particles move according to contact forces (from other particles), computed with force-displacement contact laws. For more details, give maybe a look to Yade documentation (part "DEM background").

Can you help with this problem?
