This article goes through the most popular electromagnetic solvers for periodic structures, describing their optimal use cases, advantages and disadvantages. As a practical example, a 4x4 mmWave cavity antenna array is simulated using a Time Domain Solver, Direct Frequency Domain Solver and Domain Decomposition Solver. The goal is to compare the available 3D solvers and find the most optimal settings for simulations of periodic structures.

Altair announced the release of its latest simulation solutions, which focus on next-generation connectivity, architecture, engineering and construction, as well as  a myriad of updates to Altair’s traditional solutions. 

There are some excellent updates for COMSOL Multiphysics® version 6.0. The overall emphasis in these updates was the Democratization of Simulation. It allows everyone to utilize the tools and provide feedback through the entire process of developing a model to feedback directly from production. Learn more about this release.

It may have gone somewhat unnoticed but for the first time ever, Ansys released software into the open source late last year. The software is PyAnsys, a family of Python packages providing a new, unified programmable interface to the company’s proprietary simulation stack. Learn more about this development.

A schematic editor and frequency-domain circuit solver in the latest release of XFdtd® 3D EM Simulation Software, enabling today’s most advanced antenna matching network and corporate feed network analyses.

Together with Electro Magnetic Applications, Inc. (EMA), Ansys added EMA3D Charge to its industry-leading simulation solution portfolio, addressing critical design and safety needs for applications ranging from space exploration to everyday commutes.
