I would like to simulate the operation of a machine traveling along a curved track, as shown in the picture. I would like to model the system using joints and motion, but I am not sure how to set it up because I believe that conventional joints may not be able to represent this type of track. Could you please advise me on…
I do not know why I could not access marketplace to download PSIM software. Do my account have any restrictions or licensing issues preventing access? Alternatively, if there is a direct download link available for the current version of PSIM, please share it with me. Thanks
Dear community, I recently run a winprop simulation with SRT on a vecttorized terrain landascape, and the same one with UTD in Feko (wallman produced the corresponding nasran mesh). I am a bit puzzled when I see that winprop can locate very few reflections at the surface polygons of my topography whereas feko can properly…
Dear Altair Support Team, I am teaching a CEA course using Altair HyperWorks this semester in Korea. For my class, I regularly generate Auth Codes through Altair One to authorize the classroom computers. Our classroom computers are configured to reset to their original state after every reboot. Therefore, I need to…
Since the marketplace is blocked, can i have a instalation file for edem 2026.1?

When I try to access the marketplace, the screen below appears and I cannot connect. What should I do?
Hello, I have a design of printed LPDA (100MHz - 2GHz) designed from first principles and the results are okay. The design is implemented on FR4, wih top and bottom feedlines, therefore no groundplane. However, I need to make it compact to be able to fabricate, as a result, I have reduced the spacing factor and the s11…
Hello, I am using Altair EDEM 2026.1 through the Altair Student Edition on Ubuntu 26.04.1 LTS. EDEM was working previously with this same Student Edition license, but it has stopped checking out the EDEMGUI feature. EDEM reports: License Error -29: Requested CT/TTF license not found for given customer ID I checked the…

다음과 같은 Boost converter 회로를 구현한 후 제어기를 달아 확인하기 위해 저항에 12/8.333 부분을 반부하 12/(8.333/2) 형식으로 update하였습니다. 하지만 이 과정에서 출력 전력이 원하는 100W → 50W 가는 것이 아닌 12W로 떨어지는 현상을 발견하였습니다. 해당 파형은 아래와 같습니다. 하지만 이러한 문제는 수식 형태가 아닌 상수의 형태로 실험을 진행하게 되면 문제가 없는 것으로 확인했고, 또한 open loop의 형태로 실험했을 때도 같은 문제가 있음을 확인했습니다. 혹시 이것이 PSIM 2026 시뮬레이션 자체의 문제인지 아니면…
I'm setting up a link between HyperStudy and SimLab to run a DOE. The goal is to vary the positions of components in the SimLab model and see how the responses change. The workflow runs, and HyperStudy writes parameters.xml correctly for each evaluation. However, the parameters in the SimLab simulation don't change, so…
Hi, I'm using the Personal Edition which was also designed for companies: " The Altair SLC Personal Edition can be used by everyone! It offers standard features suitable for business use, personal projects, academic research, nonprofit organizations, or anyone interested in exploring product performance using our robust…
I am trying to run a drop analysis using Hypermesh with the Radioss solver (version 2026) and I am struggling to tie together the interface shown. If I use TYPE2 connectors, I get the error that the master surface is in multiple groups. I have tried the line batch tool (set to rigid link) that graphically shows me what I…
Hello, I am working on a transient thermal analysis in SimLab 2026.1 (OptiStruct thermal). My objective is to implement a temperature-controlled heating strategy. More specifically, I would like the applied heating power to be adjusted according to the temperature measured at a given sensor location, similarly to a…
Hello everyone, I am a master's student in Power Electronics. I recently activated my Altair Student Edition license and installed Altair Flux 2026.1 on a new laptop. The Flux Supervisor / GUI opens correctly and shows the license as "Activated". However, whenever I click on "Start new project" (Flux 2D), the splash screen…
Hi I am part of a student Initiative. We get our Licenses from Siemens and can manage them over the altair one admin site. Some member are getting Error 15 and -29 when opening the program.

Hi all, I'm trying to import a periodic unit-cell mesh (Abaqus .inp format) into Multiscale Designer 2025 via New Multiscale Model > User-defined > Mesh File > Import, and it consistently crashes with: "An exception of class NilObjectException was not handled. The application must shut down." This happens even with the…
I am using Altair Inspire 2025.1 to simulate airflow generated by an axial fan operating in quiescent air. The fan geometry consists of helical (screw-type) blades designed to generate axial flow, and the fan is modeled using Rotating Components. The surrounding fluid domain is sufficiently large, and only a very small…
