Does EDEM2024.1 no longer require setting dummy particles in the Tavares UFRJ Model?
Dear all, I am trying to use EDEM2024.1's Tavares UFRJ Breakage Model to simulate the breakage behaviour of particles.Does the new version of EDEM no longer require setting up "dummy particles"? I have tried to do this way, but there has been no breakage phenomenon. Are there any UFRJ breakage cases available for reference…

EDEM API Contact Model | Not working correctly: Bonded-Particle Contact Model V3.5.0
Hi Everyone, I have been trying to implement the Bonded-Particle contact model (v3.5.0) API provided by EDEM (from its previous EDEMSimulation forums), then it works fine. But when I tried to import the geometry model(.mesh file), the bead chain model created using the (v3.5.0)API broke into particles when it collided with…

Whether the derived contact force is a single contact
Is the data derived from the contact force the force of a sing.le contact at this moment, or the total force of all contacts at this time? I saw that there is a textbook that says that it is a single contact, so I want to verify the following. Thank you.

Units in EDEM and MotionSolve for Results in HyperView
Hello, I am currently testing the co-simulation of MotionSolve, Twin Activate and EDEM using the example of an excavator (with version 2024.1): Unfortunately, I am having problems visualizing the results in HyperView. The program does not have its own system of units, but uses the sizes of the individual models. The MKS…

Oka wear model - Wrong behaviour when using deformed geometries
Hello, I am working on a wear simulation of tillage tools. I need a particle bed for the process simulation. The particle bed is supported at the bottom by a geometry element. At the sides, however, periodic boundaries are used for support. Now to my actual problem: The geometry element at the bottom should not actually…

Volume fraction calculation in EDEM-Fluent coupling.
Hello, I want to simulate flow impingement of a particle bed. The problem is that the mesh requirement in the center area of the nozzle conflicts with the requirement that the mesh size need to be larger than the particle size. For example, a nozzle diameter of 6mm requires a mesh size of 1mm. A particle size of 2mm…
