Virtual Elements for the Navier-Stokes problem on polygonal meshes [PDF]
, 2017 A family of Virtual Element Methods for the 2D Navier-Stokes equations is proposed and analysed. The schemes provide a discrete velocity field which is point-wise divergence-free.

Review of calibration strategies for discrete element model in quasi-static elastic deformation
Scientific Reports, 2023 This study first reviewed theories of the mechanical response of structures under loading, and the discrete element method provides a route for studying mechanical response including elastic deformation and structure failure.

Fully discrete finite element data assimilation method for the heat equation [PDF]
, 2017 We consider a finite element discretization for the reconstruction of the final state of the heat equation, when the initial data is unknown, but additional data is given in a sub domain in the space time.

Механика машин, механизмов и материалов, 2023 The article presents a procedure for constructing mechanical and mathematical models to describe the stress-strain state of one type of block element, taking into account its own deformation. On the basis of this type of block element, it seems promising

The soft discrete element method
Granular Matter, 2021 In order to accelerate simulations of assemblies of highly deformable grains, a novel numerical approach, called Soft Discrete Element Method (SDEM) is presented. It consists in extending the classical DEM by introducing the deformability of the grains in a simplified way.

Visualization of Results Received with the Discrete Element Method [PDF]
Computational Methods in Science and Technology, 2009 The output of discrete element simulations includes thousands of time-frames and millions of interacting particles (bodies) in each frame. A single simulation can include terabytes of results, which may lead to very large, very complex data sets. Visualizing them is coupled with difficulties caused by either the number of particles, the number of time ...

Application of Breakage Models to Particle Speeds Simulated by Discrete Element Methods [PDF]
Journal of Applied and Computational MechanicsSimulations that calculate the breakage of a given material allow for estimating the particle size produced by comminution equipment. However, conducting these simulations requires a significant amount of time and incurs high computational costs due to ...

Pointwise best approximation results for Galerkin finite element solutions of parabolic problems [PDF]
, 2016 In this paper we establish a best approximation property of fully discrete Galerkin finite element solutions of second order parabolic problems on convex polygonal and polyhedral domains in the $L^\infty$ norm.
