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…
Join us for a community conversation on how High-Performance Computing (HPC) and Simcenter PSIM work together to meet the increasing demands of modern power electronics simulation. During this one-hour technical session, you'll discover how leveraging HPC can speed up simulations, improve scalability, and empower engineers…
I've used S-CALC in the past but it wasn't installed when my employer updated my computer. Help Desk told me to find it online and install it. I found the S-CALC installation on the Seimens site and downloaded it. When I attempt to install, it says it cannot find MS Access Database Engine 2016 (x64). It then offers to…
Hello everyone, I am using Altair EDEM 2026 and HyperStudy 2026 (27.3232714) with the EDEM–HyperStudy Connector 2026.d9a3774. When I run the model definition in HyperStudy, the following occurs: HyperStudy successfully writes the input parameters to the EDEM model. EDEM runs normally and reaches 100%. The log reports…
I just downloaded the student version of Inspire. I activated my student license and trying to use the motion profile and it is saying license error. All the other profiles work except this one, which is the one I need most. Any way to fix this?
Hello everyone, I am attempting to build a dynamic model of a semi-trailer using a "slipper spring" suspension system. This type of leaf spring assembly lacks a fixed shackle mount on the chassis; instead, the spring end simply slides against a contact surface on the chassis. When constructing the dynamic model, I applied…
Hello, I am conducting an optimization run with Optistruct. The MINDIM size parameter of DTPL is calculated, according to the Guide, from the average mesh size and must not be less than 2-3 times the average mesh size. Regarding this, the average mesh size is calculated from all model or just from the components included…
Hi everyone, I’d like to know what the good specifications are for a computer that can run Hypermesh and OptiStruct student edition without any problems? I’d also like to know how I could recover my license key since my computer was stolen.

Dear Support Team, I am currently experiencing an error with my PSIM license, and I am unable to use the software properly. Could you please reissue or reset my PSIM license so that I can use the software again? Please let me know if you need any additional information from me. Thank you for your assistance. Best regards,
Hi everyone, I am currently working with the Create AFM (Axial Flux Machine) tool in Altair SimLab 2026 to generate an axial flux motor model. https://help.altair.com/simlab/help/en_us/topics/analysis/Coils/CreateAFM.htm After generating the initial model, I need to modify some dimensions of the components (such as…
Hello, I would like to request the permanent deletion of my Altair One account associated with this email address (choong1.lee@samsung.com). I am unable to delete it myself, as it appears to be a corporate-managed account and the delete option is not available in my profile settings. Thank you for your assistance.
Hi, my Student Edition license is currently activated on a Linux installation that is no longer accessible due to filesystem corruption. I have installed Windows on the same laptop, but I cannot deactivate the previous Linux activation. Could you please reset/deactivate the previous activation so that I can activate my…
I'm using Simlab to model a vacuum machine, and in coupling with EDEM the particles should be moved upwards once it touches certain part of tube. How do i define the face to give particle velocity in Simlab 2025 Optistruct solver? Thanks Qin
Hi everyone, Looking for installers for HyperWorks 2022.1 Seems the cut off is 2024 the earliest version
How does Tdelay works for /SENSOR/NOT/ in Radioss solver in Hypermesh 2025.1? I read about in solver help and it only says Time delay. What I want to set up is to apply velocity on a crush plate untill the require force is reached and stope after a time delay. So, i set up the velocity to work untill the force is reached…
Usage Logs Menu I am no longer receiving emails containing the licence usage logs. Is this feature still active?
