Abstract: An explicit time-domain finite-difference technique for modeling zero-thickness Huygens' metasurfaces based on generalized sheet transition conditions (GSTCs) is proposed and demonstrated ...

In this work, a finite volume formulation developed for two-dimensional models is extended to deal with axisymmetric models of heat conduction applications. This formulation uses a vertex centered ...

Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can ...

First-order derivatives: n additional function calls are needed. Second-order derivatives based on gradient calls, when the "grd" module is specified (Dennis and Schnabel 1983): n additional gradient ...

In this work a Finite-Difference Frequency-Domain (FDFD) propagation method for complex urban environments is proposed. The formulation starts from the discretization of the Helmholtz equation for the ...

Estimating the trend (derivative) at a specific point in a noisy time series is difficult because naive approaches like computing differences between consecutive observations amplify noise rather than ...

Building Finch requires Cabana, Kokkos & MPI (Cabana dependencies), and json (for input files). A simple example for building on CPU is shown below. # First build ...

What Are FEM, FDM and FVM? FEM, FDM and FVM differ from one another in important ways. Understanding these distinctions is key to selecting the method most appropriate for your purposes. The ...
