The Open-Source Electromagnetic Broadband Simulator OpenSEMBA

Hope you had a great start to the year and enjoyed the holiday season!

 

What better way to start the year than by introducing one of the key tools that will be used for research at the University of Granada: The Open-Source Electromagnetic Broadband Simulator OpenSEMBA (Simulador Electromagnético de Banda Ancha).

 

OpenSEMBA is an open-source repository of codes for solving electromagnetic problems. It includes solvers based on Finite-Difference Time-Domain (FDTD), Discontinuous Galerkin Time-Domain (DGTD), Multiconductor Transmission Line (MTLN), Finite Element Method (FEM), and mesh generation tools. This repository has been mainly developed and maintained by the Group of Electromagnetism of Granada (GeG) at the University of Granada, reflecting more than 30 years of collaborative development.

In addition to the repository, a FreeCAD-based workbench developed by Elemwave provides a user-friendly visual interface for setting up electromagnetic problems without writing code. The workbench allows users to associate geometries with materials, sources, and lumped elements, define regions of interest for field, current, or voltage measurements, and generate the computational mesh. Once the model is fully defined, the workbench calls a SEMBA solver to compute the electromagnetic response of the system.

Within the iSense project, OpenSEMBA will serve as the main numerical simulation tool for the research activities associated Carlos J. Ramos-Salas (DC14). All algorithmic developments and methodological improvements made during this research will be fully integrated into OpenSEMBA, ensuring that they remain open, accessible, and reusable by the wider scientific community.

By combining decades of collaborative development, open science principles, and active research contributions, OpenSEMBA represents a powerful resource for both scientific discovery and training in computational electromagnetics.
