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.

Interfacing Finite Element and Boundary Element Discretizations
Applied Mathematical Modelling, 1981 This paper reviews critically various implementation methods for coupling a mechanical finite element model to an infinite external acoustic domain discretized through boundary-element techniques. The associated physical problem is that of a three-dimensional structure submerged in an acoustic fluid, and impinged by a pressure shock wave.

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.

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.

Convergence and Optimality of Adaptive Mixed Finite Element Methods
, 2009 The convergence and optimality of adaptive mixed finite element methods for the Poisson equation are established in this paper. The main difficulty for mixed finite element methods is the lack of minimization principle and thus the failure of ...

Enriched Stone-type dualities [PDF]
, 2017 A common feature of many duality results is that the involved equivalence functors are liftings of hom-functors into the two-element space resp. lattice.
