Altair Engineering has long been known as a leading software solutions provider for mechanical engineering, offering products such as Altair HyperMesh, Altair OptiStruct, and Altair HyperWorks. However, what many users may not realize is that Altair also provides a suite of products for electrical and electronics engineering, including electromagnetics – both high and low frequency (EMC/EMI), PCB verification, power electronics simulation and electrification.

In this blog post, we will explore these electrical engineering solutions in more detail and highlight their competitive differentiators, but before we jump into the different solutions, I wanted to highlight a few things that are universal with all Altair software solutions:

  1. Altair Units licensing model. This allows end users to access all the following tools at a lower cost than what you might expect for a single software solution with competitive tools.
  2.  No Cost Training. Altair also offers no cost training options for every customer that can be self-paced, or instructor led. Allows users to get up to speed faster and be more efficient.
