Learn how to efficiently model step skew in electric machines and generate an optimized extrusive mesh using Altair SimLab. This tutorial walks you through the full process—from geometry preparation to mesh refinement—for more accurate 3D electromagnetic and NVH simulations.…
Highlights of the 2025.1 Release The Feko 2025.1 release features extensions to many different solvers - enhancing Feko's capabilities in propagation modelling, network planning as well as general and specialist EM analysis application areas. There are various performance improvements, interoperability, and API extensions,…
Background In aerodynamic design, particularly for aircraft with delta or highly swept wings, accurate lift prediction is not just a convenience; it’s a necessity. At high angles of attack, traditional linear lift models fail to capture a critical phenomenon: vortex lift. This blog post explores vortex lift correction,…
The step by step procedure to create a parameterized 3D model from a 2D sketch of Radial IPM is demonstrated in the below video. Key steps in 3D model creation of Radial IPM: 1 Exporting 2D Geometry : The video begins by utilizing 2D sketch of the IPM motor. This sketch includes 2D components such as the stator, rotor,…
Continuing with the Short Webinars initiative from the AEC Global Technical Team (GTT), on May 29th a new instance took place. This event, titled "Tapered Section Modeling and Analysis using S-FRAME," focused on a highly illustrative workflow that demonstrates how this feature can be used effectively. Starting from the…
In this video we walk through the various functions of S-FRAME's Move Tool. This includes translation of geometry, rotation, reflection/mirroring, scaling, sloping, and more. https://www.youtube.com/embed/PHdhY6YSlKU?si=RiiPq-Luwx91Fs58
Altair Unit Licensing – A Quick Guide To clarify how Altair Units (AUs) work: Each Altair application or solver consumes a specific number of Altair Units (AUs). 1 AU equals 1000 license features. You can run any Altair product as long as enough license features are available and the required product license features are…
Abstract In this post, I explain the rule of Radioss default value of input cards. Rules No. 1: Blank → 0 When we create Radioss cards, we notice that there are many parameters which we do not input. Radioss treats those blanks as 0. No.2: 0 → Default value Radioss sets the parameters which we set to 0 or leave blank to a…
In the previous article we described the setup for the optimization of a buck converter with a Type 3 Controller. This workflow uses measurements from the output waveform to qualify the controller. But, what about the frequency domain characteristics? In this article we’ll show how to add Phase Margin and Crossover…
This session shows how to build surrogate AI models of PSIM power converters using Altair romAI. These AI reduced-order models (ROMs) can be used to run system simulations much faster, while still capturing system dynamics with high accuracy. Power converters in battery charging applications are often computationally…
