Abstract: We present a new numerical modelling approach for frequency-domain finite-difference (FDFD) wave simulations. The new approach is developed as an extension to standard FDFD modelling schemes ...

The underlying solver algorithms used in power grid (PG) simulation today are derivations of circuit simulation algorithms first developed many decades ago. In fact, the 40 th anniversary of SPICE (a ...

A Python library for solving linear systems using iterative methods, analyzing matrix properties, benchmarking solvers, and visualizing performance. The library is designed to solve large sparse ...

This MATLAB project helps you compare the performance of different methods for solving equations of the form Ax = b. It includes both direct methods like Gaussian Elimination and iterative methods ...

Fast direct solvers have emerged as a transformative approach in the numerical resolution of integral equations pivotal to electromagnetic analysis. These methods are designed to resolve the dense ...

High-frequency electromagnetic simulation has evolved from “wow, now I can see how electromagnetic fields behave” to needing to know how various EM fields interact in large, complex systems. During ...

Under the hood, multiphysics software based on the finite-element (FE) method mathematically models complex engineering and scientific problems in inductive heating, heat transfer, and ...
