Design and Verification of an Electrostatic MEMS Simulator
Thermal solvers can be used for the simulation of electro-static problems as well, since the main equations to be solved are the same: the so-called field equation. There are numerous thermal solvers on the market, [...]
Improved O(N) Neighbor List Method Using Domain Decomposition and Data Sorting
The conventional Verlet table neighbor list algorithm is improved to reduce the number of unnecessary interatomic distance calculation in molecular simulations involving many atoms. Both of the serial and parallelized performance of molecular dynamics simulation [...]
Parallelization of BEM Electrostatic Solver Using a PC Cluster
In this paper, the application of parallel-processing techniques for electrostatic calculation is presented. Evaluating the pre-conditioner used for inverting the system matrix of a boundary-element-method (BEM) electrostatic solver (Fastlap) is one of the most time [...]
Corner Charge Singularity of Conductors
In this paper, we investigate a diffusion-based simulation method for the corner singularity of a conducting object, rapidly evaluating the power-law singularity associated with the corner of the conducting object for the computation of capacitance [...]
InAs/GaAs Quantum Ring in Energy Dependent Quasi Particle Effective Mass Approximation
Considered is three-dimensional In/As quantum ring using energy dependent quasi-particle-effective-mass approximation. This model was first used by Y. Li et al. (Y. Li, O. Voskoboynikov, C.P. Lee, 2002 Technical Proceedings of International Conference on Modeling [...]
A Numerical Algorithm for Complex Biological Flow in Irregular Microdevice Geometries
Trebotich D., Colella P., Miller G.H., Nonaka A., Marshall T., Gulati S., Liepmann D., Lawrence Livermore National Laboratory, US
We present a numerical algorithm to simulate non-Newtonian flow in complex microdevice components. The model consists of continuum viscoelastic incompressible flow in irregular microscale geometries. Our numerical approach is the projection method of Bell, Colella [...]
Simulation of Carbonaceous Mesophases Micro-Textures
Carbonaceous mesophases are liquid crystalline precursor that can be spun into carbon fibers using the melt spinning process; the manufacture optimization requires a better understanding of the principles that control the carbon fiber structure development [...]
Decay of Nanostructures
The thermal relaxation of isolated (single layer) homoepitaxial islands and craters and of isolated nanomounds is simulated using a 2+1 dimensional step flow model. Numerical simulations based on adaptive finite elements are used to study [...]
New Computational Methods for Long-Range Electromagnetic Interactions on the Nanoscale
The Flexible Local Approximation MEthod (FLAME) proposed recently by one of the authors is shown to be efficient for the simulation of long-range electromagnetic interactions between nanoparticles. Other promising applications of FLAME include charge or [...]
