Starting with HyperWorks 2025.1, users can create, edit, and debug HW python scripts using the Altair Compose IDE. How to ? From within the HyperWorks > Developer ribbon, you have a debugger Icon that launches Compose in 2 modes: with no file loaded, where one can start to write scripts and execute them from scratch. From…

Skip Voltage Update Flag: This article aims to present usage of the “skip voltage update” flag in 2024. Let us consider a simple buck converter as an example to understand this feature. Here, we have made two similar buck converter circuits in which one circuit is with ideal switch and the other circuit is with thermal…
Introduction Flutter is a dynamic aeroelastic phenomenon in which the aerodynamic loads on a flexible body couple with its natural modes of vibration to produce oscillatory motions with increasing amplitude. This may lead to catastrophic structural failure and hence structures exposed to aerodynamic loads must be carefully…
Learn how to accelerate your power converter design with automated design exploration using PSIM and HyperStudy. This tutorial walks you through linking the two tools to optimize system parameters and analyze their impact on selected Key Performance Indicators (KPIs). For this workflow, you will need to install: PSIM…
Electromagnetic losses, computed by Feko, become volume heat loads and surface heat fluxes in SimLab. There, OptiStruct is used for the subsequent thermal simulation followed by thermal stress and deformation. This tutorial explains the detailed steps in SimLab. It is intended for Feko users who are not familiar yet with…
In this white paper, the jamming of a radar station and of a communication link by a drone or a swarm of collaborating drones is investigated. This involves ultra-wideband antenna design in Feko and propagation analysis over terrain in WRAP. https://us.v-cdn.net/6038102/uploads/9ZG7HU4UKV9H/agilejammingwithdrones.pdf
This article outlines the steps for importing Altair WinProp indoor database (*.idb) files into Altair SimLab. Indoor databases can be exported from WallMan to the following proprietary WinProp formats: *.idb file: A vector database (binary) for Altair WinProp indoor scenarios. *.ida file: A vector database (ASCII) for…
