Description: I am trying to use the new version of HyperMesh 2026 to create a segment set for the faces on my obstacle, but it is not working. When I export the model to a Radioss file, the segment set does not appear there. Instead it goes under sets/general. Could you help me understand what might be causing this issue…
I am using Altair Compose 2025 to run a PSIM netlist (.cct file) through the command-line interface using PsimCmd.exe, e.g.: "PsimCmd.exe" "… .cct" The simulation runs successfully when I use ideal switches (SSWI), and the results are correct. However, when I replace the switches with MOSFET Level-2 models, the simulation…
I installed Simlab 2026 from the Altair marketplace. After installation, the tool worked and I was able to import my design then mesh it. I saved my progress for the day. The next day when I tried to open the tool again, the Simlab window opens for a second and then the program crashes. On investigating further, I see that…
Hello everyone, I am currently performing a simple breakage test in EDEM and trying to compare the simulation results with experimental PSD data. I would appreciate some guidance regarding the most appropriate way to process and compare the particle size distributions. In the experiments, I only have D10, D50, and D90…
Description: AI Studioにて10^-8程度のすごく小さい値を使用する方法を教えてください。 まず、小さい値が入ったcsvファイルを読むと添付したBoxPlot.pngファイルのように統計プロット中ではきちんと数値として認識しているように見えます。 しかし、その後にNormalizeで規格化すると、添付した規格化結果.pngファイルのように小さい値の入った部分（”PreCoe1, 2”）だけ規格化が上手く動作していません。 この原因、対策を教えていただけると助かります。 （逆に10^+8のようなすごく大きい値では上手く動作しているようです） よろしくお願いいたします。 Product/Topic Name : Altair…
Is there a way to force managed license AU to be freed ? Since AU seem to sometimes be blocked from beeing released (after e.g. closing AMDC-Browser session). This is somewhat needed if Units for specific features dont level or are hosted by Altair One. When working with the minimum needed AU for my applications, it is…
Dear Altair Support, I am currently encountering an issue when trying to activate my Altair license. The system displays the error message: "This license was already activated using different HostIDs." I had a lot of difficulty with installation and it seems now that there is an error with the host computer. Could you…
Hi Altair Support, I am getting the error "This license was already activated using different HostIDs" when trying to activate my student license for RapidMiner / AI Studio. I had to reset/reconfigure my system and cannot bypass this locally. Could you please deactivate the previous activation on my account so I can reuse…
Hi Altair Community / Altair Support Team, I am a student currently using the PSIM Student Edition. I recently had to completely format my PC and reinstall Windows. Because my old OS is completely wiped, I cannot access the License Manager to deactivate my license myself. Now, when I try to activate PSIM on my fresh…
Hello Altair Support Team, I am trying to activate my Altair 2026 Student Edition software on my laptop using my activation key (L4441-5RNBZ-33Z3Q-Z958N), but I am getting the error: "This license was already activated using different HostIDs." Because of a system reinstall/network change, my current HostID does not match…
Hello, With Radioss 2025 I have two specific questions about composite elements : The composite is modeled using 3D P6_SOL_ORTH elements with LAW12. Is it possible to have a different coefficient of thermal expansion (THERM_STRESS) for each of the 3 composite directions? For post-processing with HyperView 2025, how do I…
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…
Description: Installation/Launch Problems Product/Topic Name : Altair HyperSpice 2026 Hi, has anyone encountered installation issues with Altair HyperSpice 2026? I successfully activated the license and installed the software, but the app is not available in the apps list, I needed to open in from the program files folder…
Altair SLC enhanced openradioss tensile strength simulation python no gui no mouse surfing A complete enhanced self-contained reproducible example is presented that is entirely scripted, no GUI or mouse surfing required. Results are choppy because I created only 41 frames, good for testing. Physics is scaled down to limit…
Hi, I am working on a TPMS geometry and I would like to evaluate the pressure drop and the outlet temperature of an air flow through a gyroid unit cell. I followed the tutorials on conjugate heat transfer and on the gyroid heat exchanger. However, in my case I would like to model only the fluid domain using implicit…
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):…
