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,…
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
Hi, I am new to Evolve, I was wondering if there is a shortcut 'repeat' command, similar to that of autocad ? For example: When I finished drawing a nurbs curve and exited that command, I wanted to draw another nurbs curve elsewhere, I find that each time I have to draw a new curve I have to go to toolbar and click it…
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…
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…
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
have anybody done quasistatic analysis on a structure. i am a bit stuck about boundary conditions
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…
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…
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'
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…
When I do EDEM-HypyeStudy coupling, I want to load a custom optimization algorithm in HyperStudy. Do you have any related video tutorials or graphic tutorials or official cases. Thank you
Hello, I am trying to find the python code which could be used to set the parameters (see attached image) in the implicit meshing menu of an implicit body that I generated. I am unable to find it in the documentation. Thank you, Aashish
Hello, I am running the same simulation in LTspice and PSIM (AC Analysis), but I am getting different results between the two simulations. I would like to understand where this difference could come from. It is also possible that I have not fully understood how the Parameter Sweep block works in PSIM, so I would appreciate…
