If you are working with finite wire-based structures and (perhaps) ground planes, you are probably better off using a MoM based simulator rather than a FDTD based simulator like openEMS. There are other modeling approaches, each with their own strengths and weaknesses (not to mention hybrids). A solution using the Method of Moments (MoM) is probably more suited to wire antenna structures.

Ref:įDTD is probably more suited to things like patch microwave antennas and other planar oriented structures. After all, in the end any sort of classical domain elecromagnetic simulation is based on Maxwell’s Equations. wires, as well as the boundries of your simulation. very simply put: consider surfaces/structures vs. Hence you need to understand/decide if FDTD is best suited to the type of simulation you are doing. OpenEMS uses the Finite Difference Time Domain (FDTD) method. Like any tiered development chain, I recommend you start by installing openEMS in a virtual machine (VM) first before openEMS is allowed to affect a production system (dependency collisions, environment var corruption, etc. Installation of openEMS is not for the faint hearted. OpenEMS is an interesting open Computational Electromagnetics (CEM) suite that’s been around for a couple/few years at my comment time (now end-July 2017). Posted in Wireless Hacks Tagged antenna, electromagnetic fields, ems, modeling, openems, simulation Post navigation If you prefer your models more concrete and less abstract, perhaps you should work at Lincoln Lab. If you want to start with something more intuitive for electromagnetic field visualization, this might help. You can download it for Windows or Linux.
#Fdtd wikipedia software
The software uses Octave or MATLAB for scripting, plotting, and support. Our advice? Start with the waveguide and work your way up from there.
In fairness, though, the project does provide a good set of tutorials, ranging from a simple wave guide to a sophisticated phased array of patch antennas.
In one sense, yes, but you still need to know what you are doing.
But that’s like saying Microsoft Word makes it easy to write a novel. We would like to tell you that OpenEMS makes doing things like antenna analysis easy. Enter OpenEMS, a free and open electromagnetic field solver. Not only is it a rare specialty, but it requires a lot of high-powered math. However, one of the darkest arts of the electronic sects is dealing with electromagnetic fields. Neither of those guys are likely to be the ones you want building an instrumentation amplifier. However, we know that the guy you want wiring your industrial furnace isn’t the guy you want designing a CPU. To ordinary people electronics is electronics.
