hyperstudy EDEM didn't work in evaluation
Hello, I imported some kinematic values from EDEM and used optimization and DOE to check. In the result, the changing of values didn't work.(I checked that the changing of those three values have effect on Lacey) How can I solve this problem? I just test with simple rotating mixing, it happened too. Thank you for your…

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…

[EDEM] Can we get energy loss with GPU calcuration
Hi, I'd like to get energy loss after simulation by GPU. I think currrent .dill file that we use for getting energy loss is available only CPU calculation. Do you have any idea to get it with GPU calculation.

In Hyperstudy the link didn't work
I'm following tutorial video for optimization. Defined few values using data sets from motionview and define gravity(only for import not active). And get output response using edempy_post.py In the setup the co-simulate work well. but, in Doe or optimization the changing of values in motionview didn't work. How can I fix…

EDEM Polyhedral Particle
Hi, I imported a custom polyhedral particle into EDEM 2024.1 through a stl file by using the "Import Custom Particle Shape" option. The normal size distribution option for generating the particles gives an option to scale the particles through "Radius". Can you please confirm if this "Radius" is actually the largest…

Angle of Repose
Hello, Is there an easy way to measure the angle of repose on 2023 Altair EDEM? I believe the easiest way is to pass the powder sample through a funnel and allow it to form a cone on a horizontal surface. Any suggestions for that? Thank you for your time and consideration Software: Altair EDEM 2023

How to set boundary condition on certain material particle, to make them only have degree of freedom on one direction?
How to set boundary condition on certain material particle, to make them only have degree of freedom on one direction? I found in API that velocity of particle are in magnitude, without direction. Or is it possible to define new parameters for particle class without changing system header file?

C++ C2259 error in particle body force dll packing
C2259 is caused by not define all virtual function from parent class, but after I add all functions, error still happens. Technican may can help on this one, not common tutorial. (remember to include different external working directory before packing)

How to use EDEM Batch Commands
Hi Altair EDEM community Running EDEM via command prompt is a very powerful way of running and exporting data efficiently. For automated analysis of multiple cases, not just data export, you can look at EDEMpy and we have examples of these in the EDEM calibration kits. For optimisation of multiple runs we can look at the…
