Exporting grid bin group query to csv or text Postprocessing
Hello
Is there a way to export the query table produced in when grid bin group is created?
See the image bellow
I can copy the table bellow into excel but it needs lot of data cleaning
and why does it put it in two rows is there any alternative.
Is there a way tp export the data from query to csv file where everything is in one line?

EDEM-Fluent Coupling Error
Hi,
I am having issues with the EDEM-Fluent coupling; when I read the journal file in Fluent I get the error: Error at host: Error code 126.
I am using EDEM 2021.0 and Fluent 2021 R1 with version 2.3.1 of the coupling.
I have tried the coupling on multiple computers with multiple versions of EDEM/Fluent (compiling for each combination) and get the same error on all but one that is running EDEM 2021.0 and Fluent 2020 R2.
Any ideas on how to fix this would be much appreciated.
Thanks.

As the cultivator moves forward, the soil bed follows behind. The purpose is to settle the soil bed

I have shown in the cultivator video how it was mounted on the frame. Is there any mistake in it, due to which the soil bed moves backward?

Optimizing Dynamic Systems Interacting with Particulate Materials : EDEM-MotionSolve
The combination of EDEM (Altair’s DEM high performance solver) and MotionSolve (Altair’s Multi-Body Dynamics solver) unlock great potential to optimize equipment that interacts with particulate material. DEM can be used to simulate soil, aggregates, ore, or even biological material like crops. Building physical prototypes is expensive and time consuming – why not shorten your design cycle with highly accurate simulations?
How Does EDEM-MotionSolve Coupling Work
EDEM is used to solve the interaction of the particulate material and itself or the environment it is in and MotionSolve is used to resolve the dynamics of the system. The positions and directions of forces and torques are sent to MotionSolve from EDEM at each communication interval. MotionSolve uses these inputs to resolve the dynamics of the systems and passes back to EDEM the displacement and velocities of the components.
How to get Started with EDEM-MotionSolve
To get started with coupling EDEM and MotionSolve have a look at the EDEM e-Learning topic EDEM - Coupling with MotionSolve eLearning.
Application of EDEM-MotionSolve

EDEM Tutorial: Breakage in Cone Crusher
Update March 2025 - This is an outdated tutorial guide, for latest tutorials including Taveras breakage please see:
https://community.altair.com/discussion/33339/edem-tutorials
This tutorial refrences an API version of the Breakage model which is no longer supplied with EDEM, recommendation is to review the SAG mill tutorial from the above link to become familiar with Breakage.
Original Post:
Through this introductory tutorial you will learn how to set up and analyse an EDEM simulation that uses the Tavares Breakage Model. This model is in the form of an Application Programming Interface (API) plugin. In this tutorial we will also learn how to use the breakage tool to extend the size distribution and calculate the fines at the post-processing stage. The tool is an EDEMpy script and is in the form of an executable file.
In this tutorial the Tavares Breakage Model is applied to a cone crusher that breaks materials used in mining and other material handling industries.
The main focus is on:
* Creation of breakable materials and geometry.
* Creation of dummy particles.
* Set up the API model in the Creator. (Edit 2025 - API model no longer supplied, please use in-built breakage model)
* Set up appropriate timestep.
* Analyze the results through the Analyst.
* Export of simulation data to a .csv (text) file.
* Setup and run the EDEMPy script and analyze the results.
For more information about the Tavares Breakage Model please see:

Why can't I export the XML file in my post-processing anymore? I need to modify some data.
I am using the 2024.1 version of EDEM. Why can't I export the XML file in my post-processing anymore? I need to modify some data. Does anyone know how to fix this? Thank you.
