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, I am trying to train a model in PhysicsAI 2026.0 and I am facing this error. I have used the same dataset previously to train a model using PhysicsAI 2025 and it completed fine. Anyone know what's causing this error and how to fix this? [09:58:39] (INFO): [09:58:39] (INFO): Validation records : 0 [09:58:39] (INFO):…
Does EDEM execute the full broadphase every step?
Hey, I'm an FSAE student and was simmulating our current suspensions which are double wishbone pushrod to dampers (Both front and rear), When I used the data provided from BAJA and SAE libraries, I am being able to simulate the Front SLA Susp with push rod, but as I model the rear susp I am only being able to simulate…
how can we add friction in ptcv advance joint. I see no option here Thanks and regards
I would like to know if there is a way to use Hypermesh to convert old .dat (FEMAP Nastran) files with "glue" or "Linear contact" definitions to Optistructs "TIE" or "Contact" cards. Currently even importing .dat files results in the "BGSET, BGPARAM, BCPARAM, BCSET and BCRPARA" not beeing recognised / iterpreted as…
Hello everyone, I would like to use the Streamer Criterion tool for my electrostatic simulation. The issue is that when I run it I get an error saying "Failed to compute some of the streamers". I suspect the problem is that the UI does not allow me to select my Air Bounding Box as the "Region of propagation". The input box…
When I used MotionView for the coupling of rigid and flexible components, after the simulation was completed, I used HyperView to view the relevant forces. However, in the post-processing interface of HyperView, there was a situation where the Contour (cloud map) displayed "No Result" and the Result type was empty. I don't…
Dear Altair Support Team, My name is Nguyen Nhat Huy, and I am currently studying Electrical and Electronic Engineering at Ho Chi Minh City University of Technology and Education. I am writing to request a HostID reset for my PSIM Student Edition license. I recently had to reinstall my Windows operating system, which…
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
Could anyone advise on how to force this field to appear, or how to correctly update the template within HyperMesh?
Altair SLC OpenRadioss Python Scripted Steel Ball Impact Plate Simulation No GUI A complete self-contained reproducible example is presented that is entirely scripted, no GUI or mouse surfing requeried. The entire simulation is done without ALtair Radioss subscription.. Openradioss simulation (if using win 11 media player,…
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 !
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 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…
