A novel technique for implementing the finite element method in a shallow water equation
MethodsX, 2023 We presented a novel approach to investigate the two-dimensional shallow water equation in its primitive form. Its employs the P1NC−P1 element pair to simulate various cases: standing waves, dam-break planar, and wave absorbing with embedded radiation ...

Discrete and Continuous Models and Applied Computational Science, 2022 The problem of the correct asymptotic construction of the radial structure of linearly unstable ion-sound electrostatic eigenmodes is studied. The eigenvalue problem with boundary conditions of the first and second kind (electrodynamic and hydrodynamic ...

Absorbing boundary conditions for numerical simulation of waves [PDF]
Proceedings of the National Academy of Sciences, 1977 In practical calculations, it is often essential to introduce artificial boundaries to limit the area of computation. Here we develop a systematic method for obtaining a hierarchy of local boundary conditions at these artifical boundaries. These boundary conditions not only guarantee stable difference approximations, but also minimize the (unphysical ...

Energies, 2023 When solving open-region electromagnetic scattering problems using the standard finite element method, the infinite region exterior to the scatterer must be truncated with an artificial outer boundary. In the interior or finite part of the domain, finite

Absorbing boundary conditions for inertial random processes [PDF]
Physical Review E, 1996 A recent paper by J. Heinrichs [Phys. Rev. E 48, 2397 (1993)] presents analytic expressions for the first-passage times and the survival probability for a particle moving in a field of random correlated forces. We believe that the analysis there is flawed due to an improper use of boundary conditions.

OpenCL-Based FPGA Accelerator for 3D FDTD with Periodic and Absorbing Boundary Conditions
International Journal of Reconfigurable Computing, 2017 Finite difference time domain (FDTD) method is a very poplar way of numerically solving partial differential equations. FDTD has a low operational intensity so that the performances in CPUs and GPUs are often restricted by the memory bandwidth. Recently,

Assessment of a PML Boundary Condition for Simulating an MRI Radio Frequency Coil
International Journal of Antennas and Propagation, 2008 Computational methods such as the finite difference time domain (FDTD) play an important role in simulating radiofrequency (RF) coils used in magnetic resonance imaging (MRI). The choice of absorbing boundary conditions affects the final outcome of such

Absorbing boundary conditions [PDF]
, 1995 The GIBCs discussed in the preceding chapters were designed to simulate the surface properties of a scatterer, thereby eliminating the need to consider fields interior to the body. There is, however, another purpose for approximate boundary conditions, and this is to create a boundary which does not perturb a field incident upon it-in effect, to ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
