I want to know how we can solve this problem, because I need to activate the License as soon as posible because I need to use the EDEM software to make simulations. I would like to knew when…
Hello, I'm trying to follow the "Parts and Instances" section of the optistruct User Guide, where is explained the use of BEGIN, FEMODEL and END, FEMODEL to import parts into a solver deck, to then use RELOC and INSTNCE cards to manage part instances in the model. The documentation instructions are as follows: BEGIN,…
I have been lately experiencing issues that the rebuild function does not create the washer split around 2D holes anymore. I have used this function often and found it very useful but irregardless of my hole size there has been more failure than success when using it recently. If anybody can share some light on the matter…
Hello everyone, Is it possible in EDEM to automatically remove a particle from the simulation immediately after it impacts a specified surface, similar to an “escape” boundary condition for discrete-phase particles in Fluent? I would like the particle to collide with the surface and then disappear, without rebounding or…
I have installed the HyperWorks on my laptop, and the student license has been successfully activated. However, when I try to launch HyperMesh, a license popup window appears and the software does not open properly. I have already completed the installation process and activated the license, but the issue persists. The…
My licence has expired during what seems to be an inopportune moment with the Siemens integration, I am currently unable to renew on the Altair Marketplace and the Thea website seems to be down; while on the Siemens website there is no trace of Thea as of yet. Any advice or clarification would be greatly appreciated.
I cannot access the Thea Render website and am unable to complete my purchase. My license expires today, so I would really appreciate any urgent assistance or guidance on how to proceed.
안녕하세요? 인스파이어 2025를 실행해서 조작하다보면 갑자기 인스파이어가 꺼져버립니다. 특히 OptiStruct으로 해석한 후 해석결과를 열어볼때 거의 100% 꺼져버립니다. Simsolid로는 해석도 되고 결과파일도 열어볼수 있습니다. 심솔리드로 해석한 후에 위상최적화를 진행하고 결과도 볼수 있는데 다시 위상최적화 한 결과에서 구조해석을 하면 또 죽어버립니다. 첨부의 그림은 인스파이어가 설치된 컴퓨터정보이고 첨부의 STMOD화일에서 옵티스트럭으로 해석을 진행한후 결과를 열면 인스파이어가 즉시 종료됩니다. 그래픽카드를 오늘 다시 최신버전으로 클린설치를 했는데 동일하네요.…
Hello everyone, I'm having trouble activating the EDEM license, and I would appreciate some help troubleshooting this issue.

Dear Altair Technical Support Team, We are currently performing a one-way CFD–DEM simulation using a steady-state flow field exported from FLOEFD and imported into EDEM. The Schiller and Naumann Drag and Magnus Lift models are used to calculate the fluid forces acting on the particles. The actual particle diameter in our…
