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…
Hello! In FlightStream are the aerodynamic influence matrices stored in the .fsm simulation file? I've been (unsuccessfully) trying to prevent recomputing them when loading from a .fsm. Is there any way to achieve this? Kind regards, Alfonso
Hello, I am having trouble meshing some complex geometrical parts with FlightStream. Are there any best practices to follow when meshing with third-party software, or things I should avoid? Thanks you !
Dear Altair Support Team, I hope this email finds you well. We are currently using the bingham type within the VISCOSITY_MODEL command in AcuSolve to simulate a non-Newtonian fluid and have some questions regarding its parameterization. Upon reviewing the model's governing equation in the AcuSolve documentation, we…
Respected Altair Community, I was using Twin Activate software a few days back and it was working well, but for sometime now i can't able to login with my user credentials, i am getting below message in license log. I was using my Altair username and password and tried to enter i can't enter. I was using this software with…
Right now, I am working on my undergraduate thesis and trying to validate my simulation. However, I am having trouble matching the pressure drop reported in the reference paper. Could you help me identify what I might be doing wrong?
Is it possible to plot: Short Circuit Current / Open Circuit Voltage against the Field Current in Altair Flux/FluxMotor ?
Hello everyone, I am an engineering student at the Federal University of ABC (UFABC) and I have been actively using the Altair Student Edition (specifically HyperMesh) for my academic coursework. Recently, I had to completely format my PC. Unfortunately, I did not deactivate my student license beforehand. Now, when I try…
Description: Hypermesh2025.1でサーフェスメッシュ作成後にボディメッシュ設定が終わったファイル(.hm)をLinux環境のサーバー上でボリュームメッシュ作成を行うためのジャーナルファイルの作成方法を教えて頂けますでしょうか？ Product/Topic Name : Linux環境/ジャーナルファイル/ボディメッシング/バッチ処理
I am using Altair Flux 2D and would like to save or export geometry figures, field distribution plots, 2D graphs (such as torque, back-EMF, and magnetic pressure), and 3D visualization. I want to save/export the results in high-quality image formats such as TIFF (.tif) or PNG (.png).
I am working on a motor vibration / structural analysis workflow. My goal is to compute electromagnetic forces in Altair Flux, and then apply those forces as structural loads in ANSYS Mechanical. I understand that the standard Altair workflow is usually Flux → SimLab / OptiStruct for motor NVH analysis. However, I would…
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…
I would like to understand how PSIM determines the maximum allowable simulation time step for a circuit. According to the PSIM documentation, the allowable maximum time step is calculated automatically and compared with the user-defined time step, and the smaller value is used for simulation. However, I have not found…
i have FEKO 2026. i have a very large model of gulfstream aircraft. the file size is 30MB. if i add simple geometry like a single wire and save the file size increases by 30MB, basically doubling. then if i add another wire and save the file size becomes 90MB. so every time i change geometry FEKO adds 30MB. what do you…
Hii everyone, I tried calculating PSD moments my own for damage calculation and want to compare the hyperlife tool results. I exported PSD stress vs Freq plot for an element. I used statistics in hypergraph it gave the area under curve as 5201.201 which is essentially M0, using the rectangualr integration formula given by…
