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,…
Hello, I imported a 3D model from Dragonfly into HyperMesh 2024.1, as shown below. The model already contains a 2D surface mesh. I am trying to generate a coarser 3D tetrahedral mesh. However, after increasing both the average and minimum element size, the number of 3D elements does not decrease significantly beyond a…

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…
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…
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'
Mon ordinateur portable est récemment perdu, alors j’en ai acheté un nouveau. Malheureusement, je n’ai plus accès à l’ancien ordinateur portable, ce qui signifie que je ne peux pas suivre moi-même les instructions pour désactiver la licence Altair Student Edition. Serait-il possible de désactiver la licence associée à mon…
Hello Altair Support Team, I am using Altair HyperMesh/OptiStruct Student Edition on my laptop. I am getting the following error when I try to activate my license: “Error activating license: This license was already activated using different HostIDs.” I was previously able to use the Student Edition on this same laptop.…
So far one has to go to 3D to see an overlayed map (tiff, or bmp of the area under study). Can this be done simply in the 2D viewer as well?
Hello Support Team, My laptop recently broke down, so I purchased a new one. Unfortunately, I no longer have access to the old laptop, which means I cannot follow the instructions for deactivating the Altair Student Edition license myself. Would it be possible for you to deactivate the license associated with my previous…

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…
