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…

EDEM API
Good day, I hope this message finds you well. I am trying to get started with EDEMAPI using the tutorials on the website. However, I discovered that some of the tutorial are not working. Also, some of the codes are different what is in the tutorial videos on YouTube. Does anyone have an explanation to this. Thank you.

How to achieve the conical swing of a cone crusher?
This is my exercise setting. Two stacked Sinusoidal Rotation Kinematics，but this motion is not a conical swing around the z-axis, but a swing towards the positive x-axis direction. How should I set it up? Thank you.

[EDEM] CUDA GPU Error
EDEM failed to load: CUDA Error nvcuda.dll This may mean that there is no NVIDlA driver installed on your system. EDEM could not detect a supported NVIDIA driver on the system. This may be because there is no NVIDlA driver installed or because the installed version is too old. Note that there is no need to install the CUDA…

Breakage PSD Comparison with Experimental D90 and Agglomeration
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…

Hi, Is EDEM and Abaqus coupling possible under the student license of EDEM?
Description: I need to perform a coupled analysis between EDEM and ABAQUS. However, currently I have a student license of EDEM. As a beginner to EDEM, I couldnt find the coupling option between these two. I suspect this feature is not available under student license. Can anyone confirm on this? Thanks in advance.…

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.…

When coupling EDEM-Fluent, where is the scaling factor adjusted?
Hi everyone, I'm currently trying to simulate a close-packed bed. Due to the extremely small size of the actual particles, I need to apply a coarse-graining approach to reduce the computational cost. However, I'm having some trouble with the exact setup. Specifically, I can't seem to find where to actually input or…

EDEM2024 Bonding V2
Dear Professor, I would like to ask two questions regarding the bonding V2 model. (1) Suppose a bond is generated between particles A and B. During the simulation, the bond breaks due to external loading, and the center-to-center distance between A and B exceeds the contact radius. In this case, will the bond be unable to…

How are internal particle IDs assigned in EDEM, and is there any API access to newly created particl
Hi everyone, I have a follow-up question regarding particle creation through a custom API factory. I am currently generating stems continuously during the simulation using a custom factory. For each created particle, I already assign several custom particle properties, including: local particle ID StemID StemElementType…

How can I prevent unwanted bonds between separately generated stems when using Bonding V2 in the EDE
Hello everyone, I am currently developing an API-based stem generation workflow in Altair EDEM and I am using Bonding V2 to create bonded stems (meta-particle-like chains made of segments and knots). My stems are generated programmatically during the simulation using a factory-style approach. Each stem consists of multiple…

Question About PSD Calculation in Tavares Breakage Model
Hello, I have a question regarding the Tavares breakage model in EDEM. I am using the Tavares breakage model, and I want to obtain the particle size distribution (PSD) of my particles after breakage. However, I am facing an issue: the PSD obtained from EDEM after breakage is very different from the real experimental…

[EDEM] Can spherical particles bond with sphero-cylindrical particles through Fibers Bonding Model?
Hello everyone, I am trying to use the Fibers Bonding Model in Altair EDEM 2026 to create bonds between spherical particles (spheres) and sphero-cylindrical particles. However, the bonding behavior is not what I expected. I used the Volume Packing tool to generate a packed bed of spherical particles inside a closed…

Question about a post regarding MotionView coupling with EDEM and Inspire in the community.
This post explains using Inspire to parameterize the geometry, then importing the parameterized model into EDEM, and finally coupling it with HyperStudy. I understand all the steps up to this point. However, I’m confused about the part where the parameterized geometry is imported into EDEM and then coupled with MotionView.…
