Multigrid iterative algorithm using pseudo-compressibility for three-dimensional mantle convection with strongly variable viscosity
Masanori Kameyama, Akira Kageyama, Tetsuya Sato
A numerical algorithm for solving mantle convection problems with strongly variable viscosity is presented. Equations for conservation of mass and momentum for highly viscous and i…
A Note on the Dipole Coordinates
Akira Kageyama, Tooru Sugiyama, Kunihiko Watanabe +1
A couple of orthogonal coordinates for dipole geometry are proposed for numerical simulations of plasma geophysics in the Earth's dipole magnetic field. These coordinates have prop…
The "Yin-Yang Grid": An Overset Grid in Spherical Geometry
Akira Kageyama, Tetsuya Sato
A new kind of overset grid, named Yin-Yang grid, for spherical geometry is proposed. The Yin-Yang grid is composed of two identical component grids that are combined in a complemen…
Design and optimization of tapered structure of near-field fiber probe based on FDTD simulation
Hiroaki Nakamura, Tetsuya Sato, Hirotomo Kambe +2
The finite-difference time-domain method was employed to simulate light propagation in tapered near-field fiber probes with small metal aperture. By conducting large-volume simulat…
Rigidity of Orientationally Ordered Domains of Short Chain Molecules
Hiroaki Nakamura, Susumu Fujiwara, Tetsuya Sato
By molecular dynamics simulation, discovered is a strange rigid-like nature for a hexagonally packed domain of short chain molecules. In spite of the non-bonded short-range interac…
Relaxed States of a Magnetized Plasma with Minimum Dissipation
B. Dasgupta, P. Dasgupta, M. S. Janaki +2
Relaxed States of a slightly resistive and turbulent magnetized plasma is obtained by invoking the principle of minimum dissipation which leads to curl curl curl B = λB . A solutio…
