Abstract Altair Feko supports extensive cable modeling features, and this article will describe the latest features in more detail. The main cable feature is the combined MoM/MTL schematic link functionality. This allows accurate modelling of non-ideal (pigtail) shield connections to a device and radiation from common mode…
1.0 Introduction Discrete Element Method (DEM) simulations offer excellent insights into bulk material behavior under various operating conditions and find application in many industries like pharmaceuticals, agriculture, construction and mining, etc. Explore EDEM applications through webinars However, such high-fidelity…
This white paper shows how Altair® Feko® and Altair® WRAP™ are used to design antennas that achieve a required communication data rate between a geo-stationary satellite and an aircraft.
For deactivating and activating an entity using Altair Radioss, there are different approaches: Time to start and to stop Modify function curve Sensors Engine keywords (/BCS, /BCSR, /INIV) – Example for that: In this article, we will present SENSOR, that is another way to activate and deactivate entities, and have some…
In this video, we will be exploring how to use S-FRAME's Truss Generation wizard to produce trusses with various geometry, spans, and more.
Close-In Explosions generate high-pressure shock waves that can result in significant structural damage, including spalling, cracking, or complete failure of the slab. The study of such phenomena is crucial for designing concrete structures that are resilient to blast events, especially in high-risk areas such as military…
We’re thrilled to announce the release of Inspire Extrude 2025. It has powerful new features, enhanced accuracy, and improved workflows. This release is designed to optimize performance, streamline processes, and provide more precise analysis. Top 3 Key Highlights: New Profile Nose Cone Animation: Visualize and analyze the…
Altair romAI uses neural networks and systems theory to create Reduced Order Models (ROMs) from existing simulation data or field tests. Even though it is an easy-to-use tool, when I first started using it, I often found myself unable to train ROMs properly. With some research and a little bit of trial and error, I’ve…
Introduction In order to model fluid-structure interaction with OS one should consider the type of fluid he wants to study. One way is to look at the bulk modulus of the material that can be defined as: where ρ is the density and c is the speed of sound. Since compressibility is the inverse of the bulk modulus, fluids with…
Simulating Radio & Radar Coverage and Evaluating Interference This second part shows further cases how the radio & radar coverage can be predicted and the interference can be evaluated using Altair Feko with WinProp and WRAP technologies. Case 4: 6G Reconfigurable Intelligent Surfaces and Non-Terrestrial Networks Including…
