How export non-spherical particles in EDEM?

Hi,

I want to create a non-spherical bed of particles and use the results as the geometry of my CFD simulation. When I wanted to export my particles via export as stl, the software gave me error that exporting cannot be done for this particle shape.

How can I export non-spherical particle shapes as stl file?

Thanks.

Hi,

Unfortunately the export to STL functionality isn't available for polyhedral particles currently. This is set as a feature request with the product team.

You can export the particle position, orientation and size from the Analyst > File > Export results data option but this comes out as .csv format.

Hi @Mostafa Jafari Gildeh_21173,

Here's an EDEMpy script that exports all polyhedral particles in your simulation at a specified timestep as an .fem. That .fem can be converted to .stl with HyperMesh, for example. This script works with EDEM 2025 or newer versions.

To use it, just place the file in the same folder as your simulation, then go to the Analyst and click on File > Run EDEMpy Script. In the new window, click on … and select this script. Under arguments, write the time you want the particles to be exported.

Best regards,

Renan
