Different Particles Geometry

Hello,

I was wondering if it's possible to generate hollow particles or shapes, rather than just solid spheres. Specifically, I would like to generate thousands of hollow cubes in the same way angular or spherical particles are generated. The attached figure shows an example of the desired shape. I also have an STL file ready for upload, which I assume will be necessary.

Thank you for your time and consideration

Hi Ibrahim

You can use this shape directly as a particle shape in the 2024.1 version. Please check lesson 4.3 for more information.

Alternatively, in the previous versions, you can use the 'sphere fitting' tool to fill the CAD with multiple spheres and then run the simulation. Please check lessons 4.5 and 4.6 for more information.

Hope this helps.

Thanks,

Hi Ibrahim,

In Addition to Jerrin's comment, i would suggest the below method as well.

the hollow tube cross-section below can be modeled using multi-sphere as well to do so all you need is coordinate points and the radius of the sphere.

Hope this helps.

Thanks,

Hi Ibrahim,

If you use EDEM 2024.1 you will be able to import that shape of particle using a polyhedral particle as there is now support for concave shaped particles. I have attached a video from EDEM 2024.1 using the poly particle along with the EDEM deck and the Inspire model I used to create the particle.

Using the approach that Prasad suggested may be more computationally efficient than using the polyhedral particle. However, the surface of the multi-sphere particle will not be as smooth as the poly particle.

Hope this helps!

Kind Regards,

Eric

Thanks, everyone! It was easier than I expected. I just uploaded my SOLIDWORKS model in STL format to EDEM and then used the multi-sphere method to replicate the geometry for the simulation!
