Frequency Selective Surfaces (FSS) Modeling Improvements in Feko Antenna, Radome and RCS Problems Frequency selective surfaces (FSS) are periodic Metasurfaces with identical two-dimensional arrays of elements arranged in a multilayer dielectric substrate. They form a 3D-filter for incident electromagnetic plane waves and…
Highlights of the 2024.1 Release Feko Model Protection Model protection was extended to allow a custom 3D representation to be shown when a protected model is imported by a client. The 3D representation does not get meshed and does not form part of the simulation. The custom representation geometry is specified by the…
1. Introduction The static angle of repose test is a common method of material model calibration for Discrete Element Method (DEM)--based simulation. The test is suitable for evaluating particle interaction properties through bulk matter behavior under dynamic flow regimes. Static Angle of Repose (SAoR) is the cone angle a…

1D, 2D and 3D Lookup Tables in PSIM Aside from its core electronics simulation capabilities, PSIM offers a flexible environment for creating custom signals out of known data and customizing simulations in general. Key tools include controlled sources, math blocks, script blocks, and lookup table blocks. This article…
Learn how to train and use an Artificial Intelligence model using romAI to predict the dynamic response of critical components of a wheel loader in a fraction of the time it takes to run the computationally heavy DEM simulations. By attending this webinar you will learn how to: * Prepare EDEM data for reduced order model…
To install Inspire and manufacturing applications on a machine with no internet access, you will first need to download packages from a machine connected to the Internet, then transfer packages on the target machine and install there. Detailed steps are provided below: On a machine connected to the Internet, download the…
This articles discusses the guidelines for defining a time signal in POSTFEKO. The time signal that can be created depends on the simulated frequency range and frequency sampling. Follow these basic guidelines when defining a time signal: Total signal duration ( ) For a given total signal duration of , the lowest frequency…
Creating tire files is a complex and expensive process. For MF-Tyre/MF-Swift tire files, a minimum of five parameters are required: Magic Formula version number (FITTYP), Free tire radius (UNLOADED_RADIUS), Nominal section width (WIDTH), Nominal rim radius (RIM_RADIUS), and Nominal wheel load (FNOMIN). The remaining…
In this video we will look at how we can determine our support reactions in our model using S-TIMBER. This includes displaying the results graphically, as well as presenting them in a spreadsheet form. For more info on S-TIMBER, check out our website: www.altair.com/s-timber
