Join us for a community conversation on Simcenter PSIM, designed to help engineers and simulation users overcome common challenges when building PSIM schematics and running simulations. Many issues labeled as "PSIM Solver Issues" are often rooted in controls design, model definition, setup, or general simulation practices.…
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…
Hello, I installed Altair PSIM 2026 and activated my Altair Student Edition license. The activation appears successfully in Altair One, and the license is valid until September 2027. However: PSIM opens, but I cannot create a New Schematic. After a while, PSIM displays: “Connection to the license server is lost. The…
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…
My laptop with my Student Edition license activated on it has stopped working. Could someone please deactivate my license so I can activate it on another computer? My registered email is s225519768@deakin.edu.au License key: LJJS5-DZ6C2-CV3CM-A71SD
Hello, Months into using PSIM, I got a popup saying I had 30 days left on my license. My student edition license activation key should be valid well into 2027. I looked for my license file, and it has disappeared. I haven't touched the license file and its not in my recycling bin. I tried to create a new license with my…
Hello, I have a trajectory and I wanted to specify it above mean sea level, or independent from the terrain. Switching choice from this menu has no effect and the trajectory is systematically interpreted above ground. What could be the reason? I use v.2026. Thanks, Nicolo'
Hello, I previously activated my altair student edition license on an old computer. I have no longer access to the old computer and I have installed Flux and FluxMotor on a new PC. I am unable to activate my student license because it is still associated with the hold hostID. Could you please deactivate/reset the previous…
Hi, everyone! Currently I am working on a simulation of cold plate. This is my first project in HM. Can you help me out with how I can learn HM for pre-processing? My current needs are 1D meshing, Surface meshing, volumetric meshing and quality check. Do you have like recommendations about resources and what things I…
Hello! I'm a university student who's currently using Altair AI Studio for one of my courses. I originally installed and activated AI Studio about 6 weeks ago using the Student Edition instructions provided by my university. Everything was working normally during this time. Here's what I did for my initial set up: Created…
Hi, I’m experiencing the same issue as other colleagues with PSIM installation. The installer reaches 100%, but the installation wizard never opens. I’ve already tried all the solutions suggested in other discussions, including the recommended Java versions and running the installer with LAX_VM, but the issue persists.…
I am interested in seeing the forces applied to a model. Since Hypermesh has the internal Loads Summary Tool i used this to sum up all the forces and moments (about the origin) due to the applied load (in a selected load collector). I was then confused by the results, because: The total vertical force was only equivilant…
I want an idea on Altair SAO Since we have 2021, we wanted to know if any recent change has been done as I see only 2022 as the latest version and Its been named Insight Pro
Hi Altair Community, In HyperMesh 2025, after using a command/tool and completing the operation, I often need to use the same command again. Is there any keyboard shortcut that can recall or repeat the last-used command without having to select it again from the ribbon or toolbar? For example, if I use a meshing or editing…
Dear Altair Support, I had FEKO installed on another PC, so I can't activate the license. The screen displays the message "Error activating license. This license was already activated using different HostIDs". If you can help me solve the problem, I would be grateful. Best regards. Pablo
Hello Altair team, I am using PSIM 2024.1 (24.1.0.3323) with the PSIM embedded Python 3.12 API for an academic DAB/CLLC converter study. Before using a physical switching model in the converter study, I performed one preregistered smoke test only on the unmodified official Wolfspeed C3M0032120K SPICE DPT example bundled…
I want to perform a topological optimization on a solid component. I performed an initial analysis by meshing the entire solid and then selecting only a few mesh elements, to which I assigned a "non-design space" property. Since the manual selection was too time-consuming and inaccurate, to correctly divide the mesh…
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…
