Does anyone know how to do this in Hypermesh? I can't find a setting in preferences or parameters. The meshing tools remember what options were used last but this doesn't seem to apply to the auto remesh. Thanks
I activated my student edition license using the almutil_gui.exe program on my computer. I got confirmation that it was activated, and my activation key now exists in the license store. However, the license log on Inspire Cast shows a "failed to activate" message. Has anyone experienced this before? What is the solution?
I've used S-CALC in the past but it wasn't installed when my employer updated my computer. Help Desk told me to find it online and install it. I found the S-CALC installation on the Seimens site and downloaded it. When I attempt to install, it says it cannot find MS Access Database Engine 2016 (x64). It then offers to…
Hello, my old computer where I first installed Altair has stopped working and I cannot deactivate my license there to activate it in my new laptop. Is there any way I can get a new license as if I renewed? Thank you in advance.
Hello, My 2025 S-frame was working but when I updated to 2026 I encountered several errors: I can't create new models. It gives me the following error and I can't proceed: When I open existing models, the steel database is missing from the sections tab and settings… Should I just revert back to 2025? Thank you, Kendrick
S-frame 23 unable to open file and show BS5950.DAT does not exist!
How does Tdelay works for /SENSOR/NOT/ in Radioss solver in Hypermesh 2025.1? I read about in solver help and it only says Time delay. What I want to set up is to apply velocity on a crush plate untill the require force is reached and stope after a time delay. So, i set up the velocity to work untill the force is reached…
안녕하세요 Altair 지원팀, 현재 PSIM 학생용 라이선스를 사용 중입니다. 최근 가상머신(UTM)의 윈도우 OS에 오류가 발생하여, 기존 가상 디스크를 삭제하고 윈도우를 새로 설치했습니다. 이로 인해 시스템의 Host ID(MAC 주소)가 변경되었으며, 기존 활성화 키를 입력하면 "Error: Unable to access license store"라는 오류 메시지가 나타납니다. 기존 가상 디스크가 완전히 삭제되었기 때문에 제가 직접 라이선스를 비활성화(deactivate)할 수 없는 상황입니다. 새로운 시스템에서 라이선스를 다시 등록할 수 있도록 초기화(Reset)를…
Hello Altair Support Team, I am currently using the Altair Student License for PSIM. Recently, the Windows OS on my virtual machine (UTM) crashed, so I had to delete the virtual drive and install a fresh Windows OS. Because of this, my system's Host ID (MAC address) has changed. When I try to enter my activation key, I get…
Hello, I registered my Altair One account using my official university email address. In Altair One > Managed Licenses, I can see the HWPSIMPowerSupply license, and an expiration date is shown. However, when I launch PSIM 26.0, I get the following error: Feature: PSIMPowerSupplyFeature Error Code: -29 Requested CT/TTF…
Is there a way to represent missing values in a .hwascii file that contains multiple scalar results? I tried leaving blank fields for elements that do not have a value for a specific result. However, it seems that HyperView does not interpret empty fields correctly. Instead, it shifts to the next available value in the…
Hi everyone, I’d like to know what the good specifications are for a computer that can run Hypermesh and OptiStruct student edition without any problems? I’d also like to know how I could recover my license key since my computer was stolen.
Hello I have some issues when modelling a fan at the exhaust of a rack server. I don't know if my setup is correct for modelling the fan, because it was really hard to converge. Are the issues come from the mesh or the setup itself? Also, what is immersed boundary? I always find this error when I tried to do a frozen flow…
(hypermesh 2025.1) I would like to simulate some Ergall ribs bonded to a carbon fiber shell. What is the best way to simulate this bonding? Until now, I have used freeze contacts, but with this method the bonding becomes infinitely stiff. Since I am using ductile adhesives that can bridge gaps of up to 3 mm (in my case…
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…
Hi all, The EDEM 2026.1 Windows installer (AltairEDEM2026.1_win64.exe) extracts to 100% ("InstallAnywhere is preparing to install...") and then closes without the setup wizard appearing. It fails the same way in GUI mode, console mode (-i console), and Windows 8/7 compatibility mode, run as administrator. Running it with…
Hello, I have a PSIM student license and I get the error: This license was already activated on another machine. I activated this license on my university lab PC. The lab computer has automatic system restore. After class, when I shut down the PC, all local license records are erased automatically. I cannot return to that…
I would like to cancel my request to delete my account.
