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…
I downloaded the Altair flux software after generating the Student License. I went to the activation application and also entered my license key. But then it shows that no host found.
안녕하세요. PSIM 2026.1 학생용 라이선스를 사용하고 있습니다. 기존 PC에 접근할 수 없어 그 PC에서 라이선스를 비활성화할 수 없습니다. 현재 PC에서 공식 Altair License Utility로 활성화하면 다음 오류가 발생합니다. This license was already activated using different HostIDs. 학생용 라이선스는 2027년 6월 3일까지 유효합니다. 현재 PC에서 같은 키로 활성화할 수 있도록 기존 PC의 활성화 해제를 부탁드립니다. 감사합니다.
We previously had Altair‑PSIM faculty licenses at our university, but we are now unable to install or activate them on new computers. The system does not recognize the license, and the installation cannot be completed. Could you advise on how to resolve this or clarify whether the activation process for academic licenses…
Hello Altair Support, I am still experiencing a license issue with PSIM Student Edition. In the Altair License Utility, when I select “User” as the License Store under the Activation tab, I receive the following error: “Error: Unable to access license store” I have already tried the troubleshooting methods suggested in the…
Hello, I have already carefully followed Steps 3 and 4, and I also performed a complete clean reinstall and license reactivation. I removed the previous PSIM installation, deleted the existing Altair licensing files/settings, rebooted the PC, installed PSIM 2026.1 again, and reactivated my Student Edition license using…
Hello Altair Support Team, I am using the PSIM Student Edition and I recently changed to another computer. I am trying to activate my student license on my new computer, but I receive the following error message: “This license was already activated using different HostIDs.” My student license is currently still activated…
Hi I am getting an error trying to get my student licsence. It says that it's already attached to my previous host id. My last computer broke down meaning that I can't access and deactive it.
Is there a channel to contact Altair directly so they can help me deactivate my license from my old computer allowing me to use my academic license on my new computer? I lost access to it and now I can't activate the software.
Hello, I recently changed my laptop and I am trying to activate my PSIM Student Edition license on my new machine. However, when I enter my Activation Key in the "Activation" tab of Altair License Utility, I receive the following error: "Error activating license: This license was already activated using different HostIDs."…
Hi I have been trying to use EDEM with a student edition license. The license activates properly, but only includes HyperViewTrans, HyperWorksEDU, and romAI. When I try to load EDEM it gives the error message: ERROR : License Error : Altair License Manager: License error Feature(s): GlobalZoneAM, HyperWorks, HWEDEMGUI…
I downloaded Feko 2026.1.2 Windows x86_64 directly from Altair One Marketplace. The downloaded ZIP fails the SHA-256 check and 7-Zip reports a CRC failure. Official SHA-256: 1135fe3e33617f4436e016b0a922590d97e9b556823f9c2289208cd01d5623f7 Downloaded file SHA-256:…
Hi everyone, I’m currently calibrating the Tavares breakage model in EDEM. I have two remaining parameters, A and b, that need to be determined. I have experimental breakage data, and my plan is to determine these parameters by matching the EDEM simulation results with the experimental results. However, manually running…
Description: HyperMeshNVHの機能の中にCorrelationがあり、実験で得られた変形モードを記述したunvファイルとAbaqusで得られたodbファイルを用いてMACの値を算出しています。unvファイルとodbファイルは同じものなのですが、HyperMesh2019とHyperMesh2024で差異があることが判りました。 1.MACの値が変わってしまう理由を教えていただけますか？ 2.HyperMesh2019でMACを算出した際のmvwファイルは残っていますが、HyperMesh2019の環境は既に失っています。HyperMesh2019をインストールするexeファイルを共有いただくことは可能でしょうか？…

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
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
