Question about Acusolve-EDEM coupling
Dear experts, I would like to raise a question regarding Acusolve-EDEM coupling. As we know, the volume filtering method is employed to handle the fluid-particle interaction calculations during coupled simulations. However, if I want to simulate variable-density fluids (such as reactive flows, saline flows, etc.), has the…

The question about Fibers Bonding Model
The Fibers Bonding Model applies a bonding force and a bonding torque to both particles according to a set of stiffnesses, which can be decomposed into: one axial stiffness, two shear stiffnesses, one torsional stiffness, and two bending stiffnesses. For two sphero-cylinder particles of the same material, a Fibers Bonding…

EDEM 2023.1버전과 hyperstudy를 연동
EDEM 2023.1버전과 hyperstudy를 연동하고 싶습니다. 두 프로그램 모두 같은 버전으로 설치하였으며, hyperstudy에서 Add model에 EDEM이 뜨질 않습니다. hyperstudy connector도 설치해야 한다 해서 설치는 했는데 EDEM이 뜨지 않습니다. hyperstudy connector에서 어떤 작업을 수행해놔야 Add model에 뜨려나요?? 아니면 학생용으로는 못하는 건가요? 안된다면 정식용으로도 할 수 있는 방법이 궁금합니다.

EDEM 2025: Spinning Friction Model
Description: While using EDEM 2025, I created spherocylinder particles. When adding physical models, according to the help documentation, the spinning friction model is not applicable in the friction model section. Therefore, I selected the standard rolling friction model. However, I noticed that within the standard…

EDEM visualizing cross section of a particle
Hi, When I make a slice plane of particles in EDEM, I want to visualize a cut-through of the particle if it lies between the clipping plane. It will be nice to color the outer shell of the particle and the core of the particle differently, so that viewers know what's happening at the particular cross section. ex) the outer…

How to understand the material diameter of multiphase flow in Simlab?
I have been working on a multiphase flow coupled discrete element model in Simlab recently. When setting up multiphase flow in Simlab, the carrier is water, and the two discrete phases are air and particles. However, the diameter appears under the material subdivision. How should I understand this? Is the diameter of the…

The Fibers Bonding Model in EDEM
The need for fibers in EDEM Fibers are fundamental in some industries like Agriculture, Construction, Fabrics Manufacturing or Battery Manufacturing, among others. EDEM has been used in the past in simulations within these fields, but it did not offer a model specifically designed for fibers. The Fibers Bonding model is a…

Consultation on Unidirectional Coupling between EDEM and Optistruct
I now see in the forum that in EDEM unidirectional coupling, EDEM obtains the force on the material and then uses finite element to perform static structural analysis. So, I want to obtain the stress changes of the material on the equipment over time, that is, to perform transient calculations. Is the method of exporting…

Is there a way to apply a force to an individual particle?
I have particles bonded in the shape of a beam, and I want to apply force to specific particles so that the entire beam experiences deformation because of that force. Currently, in the Creater section, I only see the option to add geometry and assign motion to it. But what if I want to impose motion/force directly on a…
