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…
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'm trying to install hypermesh on another pc, using the same altair one account and license, is this related?
Hello, My main target is to perform a ray tracing simulation that would account for diffraction and reflection from terrain with a 3D ray tracing simulation. Ground means only terrain, no obstacles like buildings for the moment. This triggers two questions: is it true that SRT does NOT account for diffraction from terrain,…
Hi @Rahul_P1, I am using a student/academic licence to run the Feko suite, but it seems that the licence is not activated for WRAP. This issue has been discussed in other posts on the community, but has not been solved: The following error is issued: There is no issue running all of the other Feko components nor the…
Hello, I exported a 3D model with a tetrahedral mesh from Dragonfly into HyperMesh. The model contains a very high number of elements, so I need to make the mesh coarser. I first tried to remesh the 3D elements directly, but I was not able to reduce the number of elements significantly. I then found a discussion on the…
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…
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…
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…
Hi I'd like to confirm how shear strength, ØVcz , for walls in out of plane direction is calculated in S-CONCRETE. I checked the S-CONCRETE Help and calculate shear strength manually following it. However, the results didn't match the value form S-CONCRETE. I'd like to know the reason. Thank you.
Hello, how can I get the total sum of my simulation model in case of the inertia and mass? The model used a super element and 3d-model. I like to get the sum of both to compare the reduced structure with the full 3d structure. In addtion like to compare the center of gravity. thanks
Hello, I am using PSIM 2026 Student Edition. I recently changed my computer and I no longer have access to my previous computer, where my PSIM license was activated. When I try to activate PSIM on my new computer, it says that the license is already activated on another HostID. Could you please deactivate/reset the…
Hello I have this error message Failed to create OpenGL RenderContext. when I want to display the results of my test on PhysicsAI.
Hallo everybody, I am trying to launch a topology optimization analysis with Hypermesh but I get this error message: "ERROR # 3423 MUMPS solver encountered error with code -72 Please contact support and provide .out and .stat files" I run the static analysis for the same model (with the exception of the optimisation…
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
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…
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
