This webinar provides a practical look into how Simcenter PSIM's 1D magnetics library and motor models work and how they should be used in system‑level simulations. We will explore essential modeling concepts like: Saturable cores Hysteresis effects Winding and core loss mechanisms Spatial harmonics in motors and their…
Focused on power electronics, this session shows how Simcenter Simlab’s PE and SCAC toolchains support parasitic extraction, detailed loss computations and model building for complex modules and inverter stacks. We’ll explain best practices for extracting parasitic inductances/capacitances, coupling electrical and thermal…
This webinar explores the simulation and analysis of lightning strike effects on aircraft structures using Simcenter Feko. The session will cover the fundamentals of lightning interactions with aircraft, modeling approaches for representing lightning-induced electromagnetic effects, and methods for analyzing current…
I have a polyurethane screen panel. Using MotionView, I’m not able to reproduce its motion, and the panel also needs to interact with bulk material. Therefore, I am considering using OptiStruct as the solver. However, I feel that OptiStruct does not provide as many explicit analysis control options as Radioss. So I would…
Hello, I wanted to ask how the overhang constraint is defined (within the Topology optimisation design variable card) within Altair HyperMesh when running a topology optimisation. I am designing a part for metal 3D printing and the printer cannot print within 30 degrees of the build plate, as shown in number 3. However the…
Description: Thw window selection modes "inside", "outside" and "intersect" seem to be availabe when right clicking in the view box. This inside selection mode works great, but has a caviat. When selecting lets say surfaces or elemets (something not 1 dimensional), then even if a single pixel of the specific entity is…
Hello team, I would like to check if there is a direct method available in HyperMesh 2024 (Abaqus profile) to create a set containing all properties associated with a specific part. Currently, properties are assigned at the component level, and components can be selected using “by part”. However, I am looking for: A direct…
Hi, I'm simulating the steering force and boost force when the car is stationary and simulating steering according to a sinusoidal event. The results show that the steering force when stationary is smaller than when the car is moving according to a sinusoidal event, whereas it should be larger. I'm wondering where I'm…
Is there an API/documentation for S-frame 2026? not S-foundation but S-frame itself?
Hi, I have Marc files (in *.dat format), Can I import it in Hypermesh (version 2025.1) to see the model and make some changes if required ?? Please Help, Thanks !
Could anyone advise on how to force this field to appear, or how to correctly update the template within HyperMesh?
Hello, My Altair One student account is locked due to too many failed password reset attempts. I am not receiving the verification/reset email on my university address (@alunos.utfpr.edu.br), so I cannot unlock the account by myself. Could someone from Altair support please manually unlock my account or update the email…
I am working in Simlab and have a very simple cylindrical "air" capacitor. It's comprised of: Outer housing with ID = 6.00 inches and a thickness of 0.125 inches Solid inner conductor with OD = 5.00 inches that's it, all suspended in air. I am able to extract s-parameters from the solution parasitic extraction, however…
Hello, I have installed SimLab on a remote Windows machine. The issues is that when I start the program it silently crashes. I tried the same steps on my personal windows machine and it worked. Any ideas why this might happen? When I go into windows Event Viewer I get this error Faulting application name: hwx.exe, version:…
I would like to ask whether PSIM provides a 4-terminal MOSFET model with separate Gate, Drain, Source, and Body (Bulk) terminals. I have checked several MOSFET models available in PSIM, including the built-in MOSFET models, and they all appear to have only three terminals, with the body terminal internally connected to the…
Description: Hello, I am running multi-material topology optimization in OptiStruct and I want to retrieve the results into HyperMesh to run validation analysis. Is there a way with the OSSmooth tool to get a unified result but with mesh distinction (not different size but different component assigned or property) for each…
Description: Hello, I am a student doing a master's thesis on multi-material and multi-objective topology optimization. I have successfully done both separately using Altair Hypermesh and OptiStruct, but now I was trying to achieve multi-material multi-objective topology optimization. I am trying a thermo-mechanical…
My groupmate attempted to click 'Update' in the solver settings, but we received the attached error message. Any ideas on what is causing this?
