Coupling AcuSolve and EDEM
Dear Altair Team, We meet problems when coupling AcuSolve and EDEM in SimLab and need your support.The coupled simulation cannot be paused but only terminated. Could we resume the simulation from the last time step after terminating the coupling? Waiting for your reply, thanks. Best regards

Altair Inspire Studio: Why does my app keep crashing?
For context, I use the Altair Inspire Studio 2025 R1 version to open my Altair EDEM 2022. 3-version rotary drum calciner slice simulations. At first, they would open fine, and I could work with them. Another issue I have faced is that the tutorial available on the YouTube channel isn't updated for the newest version of the…

SimLab and EDEM coupling erro.
I made a flow solution and worked perfectly, but when added the coupling it just simpliy wont starts and shows a error menssage. I know the coupling server is working beacuse i was able to transfer the geometry to EDEM. Somebody knows how to solve that and what is wrong?

EDEM Force Controller on a group of Geometries
Hi, I have a Model of 3 geometries. One is a wheel rotating about its axis with a torque controller. All 3 geometries are moving under constant velocity in Y direction. Now I would like to push all 3 geometries with 4 kN onto the particle surface. I found the parent child option. But if one part is the parent and the…

EDEM 설정 문의드립니다.
Description: EDEM 설정 문의 Product/Topic Name : EDEM 안녕하세요. LG전자 이유진책임입니다. 분체압연 캘린더링을 해석하고 있는데, 위치 갭 제어 방식이 아닌 하중 제어 방식으로 해석하려고 합니다. 현재까지는 3-roll 기준으로 롤 갭을 설정한 도면을 가져와서 사용했습니다. 1.실제 장비는 외부에서 하중을 인가하고 롤 갭도 설정된 상태로 사용하고 있어서 이를 유사하게 모사하고 싶습니다. 예를 들어 롤 1-2-3이 수평 배치된 상태에서 롤 3에 우측에서 좌측으로 하중이 인가되는 상황이라고 가정하고 롤 3에 Force controller를…

A question about configuring EDEM batch processing scripts in HyperStudy.
I'm currently facing a scenario. I have already created a .bat file for coupling EDEM with other multibody dynamics software, successfully registered it with HyperStudy, passed the model test, and completed a full DOE analysis. Now I would like to upgrade my batch processing script, but I'm not sure if this can be achieved…

EDEM Recorded Factories 기능 문의
Description: 수평배치된 연속롤 캘린더링 시스템에서 분체압연 공정시 레코디드 팩토리 기능 Product/Topic Name : EDEM Battery Dry electrode coating system 안녕하세요. LG전자 이유진 책임입니다. EDEM으로 분체 캘린더링 시스템 해석을 진행하고 있습니다. 3-roll 연속롤 배치된 시스템에서 분체를 투입하여 시트화되는 거동을 해석하고 있습니다. 예를 들어 롤 1-2-3으로 배치된 구조에서 롤 1-2를 통과한 분체로된 시트가 롤 2-3으로 투입되어 주행하는 모델을 사용하고 있는데, 해석 시간이 너무 길어서 롤 1-2에…

When can EDEM support OSFLEX body coupling in Motionview?
Because I am currently working on a project that requires consideration of the nonlinearity of the material, which needs to come into contact with particles. However, after my research, Motionview has launched an OSFLEX flexible body function, which is currently a testing function and cannot be coupled to EDEM. Therefore,…

Inquiry About Synchronizing Particle and Geometry Motion When Using the Fibers Bonding Model
We are considering conducting an analysis in which the motion of particles and geometry are synchronized, similar to the toothbrush simulation shown at the URL below. However, since the Fibers Bonding model relies on Meta-Particles, we are having difficulty establishing a bond or synchronized motion between particles and…

Can EDEM couple with the explicit algorithm of a structural solver other than OptiStruct?
I have a polyurethane screen panel. Using MotionView, I’m not able to reproduce its motion, and the panel also needs to interact with bulk material. Therefore, I am considering using OptiStruct as the solver. However, I feel that OptiStruct does not provide as many explicit analysis control options as Radioss. So I would…

EDEM–Fluent coupling
Dear Altair Support Team, Thank you for your previous assistance. The download link for the EDEM–Fluent coupling interface appears to be unavailable or expired. Could you please provide me with an updated link or a new copy of the coupling interface package? I specifically need the EDEM–Fluent coupling interface that can…

Volume for triangle edge-polyhedron contact
Hi, I am looking to develop a custom GPU contact model for polyhedra. I need to handle particle-triangle contacts differently to particle-particle ones. I am interested particularly in the overlap volume EDEM produces for a polyhedral particle falling onto an edge (where it's velocity is in-plane with the triangle). In…

Issue with a Custom Particle Property API (Particle Body Force) in EDEM 2025 during EDEM-AcuSolve co
Hello, I am running EDEM-AcuSolve coupled simulations that are similar to the tutorial (ACU-T: 6106 AcuSolve - EDEM Bidirectional Coupling with Mass Transfer). Instead of spray coating, the particles are initially given a moisture content and will get dried. My simulation can run correctly on two older computers, i.e.…
