Hello, amazing Altair community! We're buzzing with excitement to welcome you to this dedicated space, created just for you as we embark on an important transition: moving Altair's support infrastructure to the Siemens Support Center. This is a big step, and we're committed to making it as smooth and transparent as…
Hello, Just installed Altair Inspire and my trial period is only 13 days. I read somewhere on the Altair website that as an individual non commercial user, you get a 1 year renewable license? if so, how do i activate this? or is it on case-by-case basis?
In this example circuit, a phase-shifted full-bridge converter is implemented with a synchronous rectifier on the secondary. Peak current-mode control, PCMC, is implemented with a PI controller controlling the output voltage. This example is available in the example library of PSIM with this default path…
Hello, I've just update FEKO from 2025.1 to 2025.1.1. Chan launching a cadfeko file, I got the message : "Your application macro library is corrupted, please contact support" The soft works well however. Any idea how to solve this ? And by the way, do i have compatibility of files between the two versions ? Thanks a lot,…
Hi, Could you please help me with above Hypermesh or CAD files from altair?
We recently released a new eLearning course, Structural Analysis with Inspire. Structural Analysis with Inspire will give you practical experience to explore, evaluate, and optimize designs early in the development process. Use two solvers, leverage Design of Experiments, and practice applying connections, loads and…
Hello, I have trouble selecting the right thickness parameter when applying copper to my structure : I understand the thickness parameter is supposed to be the thickness of my structure. I so have four questions : 1. In the case of a mettalic cube of side 5mm, should i set it to 5mm ? 2. I can read on the tutorial that "It…
Hi, I want to measure an AC component of a DC current at the DC Battery Bus. In physical experiment I can use a rogwoski coil and put the oscilloscope in AC coupled mode to extract the AC current at a DC bus. I am trying to get a similar measurement in PSIM simulation. The current probes available in PSIM includes the DC…
Is it possible to have a particle factory where the particle is forced to start being in contact with a geometry surface? In my case I want a sphere to start rolling down a circular surface, but the particle is either generated outside the geometry or not close enough to the surface. Thank you.

Hello guys, I want to discuss structural non-linear analysis in Optistruct and better ways for it to converge. In my experience, 99% of non-convergence occur due to element distortion. Now, I calculate welded structures and I am usually interested in a certain area of the design, but I also include the environment which…
Hello everybody In order to be efficient in my work, I asked my colleague to apply pressure on my FEM in another file .hm. I export the PLOAD in a .fem file. Then I want to import the file in my own .hm, it doen't regnonize the PLOAD4 in the file. I have the following errors : A valid element for pressure 1 was not found…
Description: 图示传动轴用键连接齿轮传动，我在optistruct中想要分析轴由齿轮啮合冲击带来的振动，请问我怎么让键的网格与轴、齿轮的键槽网格共节点？从而保证连接刚度，还有就是怎样模拟齿轮的啮合冲击通过键传到轴上，希望给出相关的指导意见以及相似的案例，谢谢 Product/Topic Name : Hypermesh2025-Optistruct-振动分析

I modeled a controller for a totem pole PFC in Embed, also using PSIM coupler for plant simulation. This is the top level diagram. This is the inside of "MCU compound". it contains sense signals scaling and processing, inrush control, inner outer PFC loops. This is the inside of "VAC-iL - Bus processing" compound. I'm…
Hi, I am currently working on the design of a broadband V/UHF wire monopole antenna covering the 30–512 MHz frequency range in Altair FEKO. Although I can model a basic wire monopole structure, the antenna exhibits a narrowband response, and I am looking for methods to increase the operational bandwidth. Could you please…
Hi all, Is it possible to map casting simulation results from Inspire Cast for structural analysis? Thanks a lot,
