Numerically simulating impact disruptions of cohesive glass bead agglomerates using the soft-sphere discrete element method
Asteroids, Surfaces Collisional physics Geological processes Regoliths
2015/12/25
We present our implementation of cohesion in the parallel N-body code pkdgrav in order to model small bodies that are not fully monolithic but that have at least some degree of cohesion. Small bodies ...
An implementation of the soft-sphere discrete element method in a high-performance parallel gravity tree-code
Bulk solids Solar system DEM Hopper SSDEM
2015/12/25
We present our implementation of the soft-sphere discrete element method (SSDEM) in the parallel gravitational N-body code pkdgrav, a well-tested simulation package that has been used to provide many ...
Numerical simulations of granular dynamics:I. Hard-sphere discrete element method and tests
Asteroids, Surfaces Collisional physics Geological processes Regoliths
2015/12/25
We present a new particle-based (discrete element) numerical method for the simulation of granular dynamics, with application to motions of particles on small solar system body and planetary surfaces....

The orientation preserving topological symmetry group of
a graph embedded in the 3-sphere is the subgroup of the automorphism
group of the graph consisting of those automorphisms which can be
induc...

ON SIMULTANEOUS LINEARIZATION OF DIFFEOMORPHISMS OF THE SPHERE
DIFFEOMORPHISMS SIMULTANEOUS LINEARIZATION
2015/9/29
Let R1, R2 . . . Rm be rotations generating SOd+1, d ≥
2, and f1, f2 . . . fm be their small smooth perturbations. We show
that {fα} can be simultaneously linearized if and only if the assocated ran...

In this paper we propose a method associated with an algorithm for
generating uniformly scattered points on the the Lp-norm unit sphere and
discuss its applications in statistical simulation, repres...
Frustrated Spin Model as a Hard-Sphere Liquid
D topology antiferromagnetic ising model triangle lattice hard sphere fluid to the quantum spin dynamics
2014/12/20
We show that one-dimensional topological objects (kinks) are natural degrees of freedom for an antiferromagnetic Ising model on a triangular lattice. Its ground states and the coexistence of spin orde...
Soft spheres interacting via a hard core and a range of attractive and repulsive ‘soft-shoulder’ potentials self-assemble into clusters forming a variety of mesophases. We combine a mean-field theory ...
A mimetic, semi-implicit, forward-in-time, finite volume shallow water model: comparison of hexagonal–icosahedral and cubed-sphere grids
A mimetic semi-implicit forward-in-time
2014/12/18
A new algorithm is presented for the solution
of the shallow water equations on quasi-uniform spherical
grids. It combines a mimetic finite volume spatial discretization with a Crank–Nicolson ...
A standard test case suite for two-dimensional linear transport on the sphere: results from a collection of state-of-the-art schemes
test case suite two-dimensional linear transport
2014/12/18
Recently, a standard test case suite for 2-D linear transport on the sphere was proposed to assess important aspects of accuracy in geophysical fluid dynamics with a “minimal” set of idealized m...
