How to Create a Response to EDEM Statistical Domain Information in Hyperstudy
Just for example, I have a vibrating screen and I want to study the relationship between the static friction coefficient and the mass flow velocity (or accumulated mass over time) of the lower layer of the vibrating screen. How can I create a response? I couldn't find the statistical field I set when setting the…

Theory of particle volume fraction calculation in EDEM-Acusolve coupling
Hi all, I tried to figure out the computational details of particle volume fraction calculation in EDEM-Acusolve coupling, such as the theory and formulae, but I only found some brief introduction through the Altair Website. So can anyone tell me how to get the theory about particle volume fraction calculation used in EDEM…

Shrinkage, Particle Size Distributions, and contact Radius
Hi Everyone, I am wondering how EDEM handles the contact radius and if it is possible to achieve my goal with some work-arounds. First of all, I understand that a contact pair is registered if particles have contact radius overlap: triggering the calculateforce() function. Now what I dont understand is what are the…

Optimizing Tractor-Implement Systems with MotionSolve and EDEM
Introduction Effective tractor-implement systems are necessary for cultivating healthy crops. Traditionally, improving tractor-implement performance has relied on field testing – a process which is time-consuming, weather-dependent, and costly. In this article, we explore how MotionSolve (Multibody Dynamics) and EDEM…

Liquid bridge contact model for wet bulk material
Hi, I just found the Liquid Bridge contact model as a new contact model in Altair EDEM 2025. I assumed it could handle the cohesive/sticky material caused by the water content percentage. Is it correct? And what is the difference if we use the JKR contact model rather than this new contact model? Thanks in advance for any…

EDEMで接触パラメータを変更した後，MotionViewに反映させる方法はありますか？
MotionViewからジオメトリをEDEMに送信し，EDEM上で粒子とジオメトリの接触パラメータ（Hysteretic SpringのDamping FactorやStiffness Factorなど）を編集しました． しかし，その後にMotionSolveでシミュレーションを実行しても，EDEMで変更した接触パラメータが反映されていないように見えます． このような場合，EDEMでの変更をMotionView（またはMotionSolve）側に再反映させる正しい手順があれば教えていただきたいです． よろしくお願いいたします．

Python for postprocessing results from MotionView
Post processing after coupled simulation (MotionView/EDEM) takes a long time. Is there way I can use python to extract my results after each simulation just like what EDEMPy does? Note that I do not save much data in EDEM to save storage and I only import the main parts of the machine interacting with the soil into EDEM so…

EDEM coupling with Fluent for Two-Phase Fluid
Hello, I’m working on coupling EDEM with Fluent. In my case, the domain is rectangular, with the bottom half filled with water and the top half with air. Particles are falling from the air onto the water surface, and I want to study their behavior in the presence of water. I’m using the default EDEM-Fluent coupling…

[ EDEM ] I got Issues When Modeling Nano-scale Spherical Particles in EDEM.
I am currently working on modeling nano-scale particles using EDEM.Thanks to the kind support from an Altair employee, I have confirmed that EDEM does not directly support meshing at the nano scale and some facts as below. The Fiber Bonding model requires sphero-cylinder particles that must be meshed, but EDEM cannot…

Best Contact Model for Simulating a Partially Molten Cohesive Zone in EDEM
Hi everyone, My questions ia about choosing the most suitable modelling approach. I’m currently working on an EDEM simulation where DRI particles fall into a slag and molten metal bath inside a furnace. The particles form a feed pile that slowly melts to produce slag and hot metal. My goal is to accurately simulate the…

Replace geometry doesn't work
Hi, I am using Hyperstudy 2025, Inspire 2025, EDEM 2025 and EDEM-Hyperstudy connector 2025. I have been using this guide: In part 2 they created a parameterized stl file that I have done as well. The only difference is that I combined all parts in Inspire so I didn't have to use the mesh lines in the python code because…
