the problem described by these equations is: at time=0, N particles are dropped onto an infinite plane to diffuse. C(r,t) represents the concentration density of particles
The solution is very simple, but I want to see the procedure.
Thank you very much!
My own DEM(Discrete Element Method) program's solution for static problem seems strange.
I use my program to calculate the displacement of a cantilever under static pressure:
1. it seems my program shows convergence for static problem as the mesh gets denser. As the mesh grows denser(that means the particle becomes smaller), the displacement(of y direction) of the free tip becomes smaller.
Is there any computing module which can compute a heap of disk elements in DEM(discrete element method)?it'd be better if it is written in matlab or C/C++. I'm doing research on the combined DEM-FEM. I need such module so as to save my time.
Thank you
