Abstract In this paper, a model of the heterogeneous anelastic seismic wave problem is proposed in three-dimensional (3D) cylindrical coordinates. We use the velocity-stress formula to describe the ...

An implicit finite-difference time-domain method in cylindrical coordinates is developed using the locally one-dimensional (LOD) scheme. The Sherman-Morrison formula is utilized to solve a cyclic ...

This module covers coordinate systems, vector fields, and parametric equations. It also includes applications to electrical and gravitational attraction, electric and magnetic field diagrams, and ...

A cylindrical-grid finite-volume (FV) algorithm for the solution of time-harmonic Maxwell's equations in fully three-dimensional (3-D) anisotropic media is presented. To circumvent ill-conditioning ...
