An advection-robust Hybrid High-Order method for the Oseen problem [PDF]
, 2018 In this work, we study advection-robust Hybrid High-Order discretizations of the Oseen equations. For a given integer $k\ge 0$, the discrete velocity unknowns are vector-valued polynomials of total degree $\le k$ on mesh elements and faces, while the ...

Models for some irreducible representations of so(m,C) in discrete Clifford analysis [PDF]
, 2016 In this paper we work in the `split' discrete Clifford analysis setting, i.e. the m-dimensional function theory concerning null-functions of the discrete Dirac operator d, defined on the grid Zm, involving both forward and backward differences.

Discrete elements for 3D microfluidics [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Microfluidic systems promise to improve the analysis and synthesis of materials, biological or otherwise, by lowering the required volume of fluid samples, offering a tightly controlled fluid-handling environment, and simultaneously integrating various chemical processes.

Multiscale Discrete Element Modeling
Symmetry, 2021 A multiscale approach to discrete element modeling is presented. A distinctive feature of the method is that each macroscopic discrete element has an associated atomic sample representing the material’s atomic structure. The dynamics of the elements on macro and micro levels are described by systems of ordinary differential equations, which are solved ...

Accelerating Polyhedral Discrete Element Method with CUDA
The Astronomical Journal, 2023 This paper presents an efficient CUDA-based implementation of a nonspherical discrete element method where irregular particles are described by using polyhedrons. Two strategies are employed to exploit the parallelism of the numerical method.
