Join us for a community conversation on the impact of rotor deformation on the performance of high-speed permanent magnet synchronous motors (PMSMs). As these machines operate at increasingly higher speeds, centrifugal loading can deform the rotor and reduce the machine air gap. This session presents a simulation-driven,…
Join us for a community conversation to discover how integrated simulation can help analyze radiated electromagnetic emissions in EV powertrain systems. This session will demonstrate how Simcenter Feko and Simcenter PSIM work together to estimate emissions from a three-phase cable and assess their impact on nearby…
Join us for a community conversation on accelerating power electronics design, where you'll learn how to leverage the fast simulation capabilities of Simcenter PSIM alongside the powerful design exploration and optimization features of Simcenter HEEDS. In this webinar, we’ll show how engineers can move beyond manual…
Join us for a community conversation on Pulse Width Modulation (PWM), a fundamental technique in electric motor control, and explore how different PWM strategies can yield significantly different results. This webinar provides a comparative analysis of various PWM methods and their effects on motor efficiency, torque…
Join us for a community conversation to discover the Advanced Iterative Solver(AIS) in Simcenter Feko and its application to electrically large and computationally demanding electromagnetic models. The session will provide a general overview of how iterative solution methods can help improve efficiency of large scale…
Hello, how are you? Product: EDEM v2025.1.1 I want to get into the EDEM-FLUENT capabilities for some studies I need to perform. Following the tutorial (https://learn.altair.com/learn/course/cfd-dem-coupling-edem-and-fluent-elearning/table-of-contents/introduction-to-the-edem-fluent-coupling?page=1), when executing the…
My course requires me to create an Altair account and install Altair AI Studio 2024.10., but I ran into this error. After I clicked "Configure Altair License" and added my credentials, I also ran into this issue.
Hello, I exported a 3D model with a tetrahedral mesh from Dragonfly into HyperMesh. The model contains a very high number of elements, so I need to make the mesh coarser. I first tried to remesh the 3D elements directly, but I was not able to reduce the number of elements significantly. I then found a discussion on the…
Hello, My main target is to perform a ray tracing simulation that would account for diffraction and reflection from terrain with a 3D ray tracing simulation. Ground means only terrain, no obstacles like buildings for the moment. This triggers two questions: is it true that SRT does NOT account for diffraction from terrain,…
If you’re interested in our books, Phil and I will be sharing interesting chapters and highlights from them every week. You can also find more information about our books through the links below: https://hollandnumerics.org.uk/book-table https://www.lulu.com/spotlight/hollandnumerics
Hello, Simulating the propagation of a phased array antenna into a rural environment, I imported the far field from Feko to Winprop Proman. I see that Proman discards information concerning the far field phase. In other words, it retains only the magnitude out of the complex Feko far field data. I could retrive this…
以前のバージョンでは、拘束や荷重を設定する際にサーフェスを選択するとそのサーフェスが赤くなっていたように記憶しているのですが、ver.2026でオレンジ枠のみに変更となったのでしょうか？ プロパティエディターでの色変更は矢印のみに適用されているように見えます。 ver2026.15308
안녕하세요. Ansys Fluent와 Altair EDEM을 이용하여 CFD-DEM 연성해석을 진행하고자 버전 호환성과 관련해 문의드립니다. 현재 저희가 보유하고 사용 중인 버전은 Ansys Fluent 2024 R1 및 2025 R2 입니다. 각 Fluent 버전과 연성해석이 가능한 EDEM 버전 범위와 권장 조합을 확인하고 싶습니다. 세부적으로 아래 사항에 대해 안내해 주시면 감사하겠습니다. Fluent 2024 R1과 공식적으로 연동이 지원되는 EDEM 버전 및 권장 조합 Fluent 2025 R2와 공식적으로 연동이 지원되는 EDEM 버전 및 권장 조합 해당…
Hello, I am using PSIM Professional 2026.1.0.8096 with an Altair Student Edition license. I am currently experiencing the following issues: PSIM opens, but New Schematic and other functions are disabled. In Help → About PSIM, the Active Features section is completely empty. The Options → License Setup menu is missing, so I…
I would like to ask for advice regarding a CFD simulation in Altair Inspire. My goal is to analyze the airflow generated by an axial fan operating in still air (no ambient airflow). However, even when using an axial fan geometry, the streamlines extend almost entirely in the radial direction and show very little axial…
I have trouble opening the Hypermesh 2025.1 after downloading and installing it from Altair One, my Altair One account is valid and activated. I am attaching the screen short of the message i am getting which trying to access Hypermesh. Any help regarding this would be really appreciated. Thanks
