How to generate the shape of a structure using particles

Hi,

I would like to ask how to model a structural shape using particles. It's easier to do it for the structure with a regular shape. However, for a steel plate with an irregular shape, I try to randomly generate particles (single sphere) to fill the geometry, however, there is a large gap exist between particles in EDEM. Therefore, is it possible to build this steel plate using clumps? Or there is other better approaches to achieve it? Moreover, are there any reference sources on the Altair EDEM website?

Many thanks in advance for your help!

Chao

    Hi Chao.

    To crate particles from templates:

    The large gaps between particle may be adjusted by changing the Smoothing Value that will optimize the particle shape you're trying to create.

    Check the EDEM elearning lesson 4.5 - Generating particles from a template for more information.

    Volume packing tool for complex shapes

    For your case, you could use the Volume packing tool that will create a complex bed of material that in your case in the steel plate shape. Check lesson 12 of the EDEM elearning that further explain how to use this tool.

    Hi Chao,

     

    Easiest way is use the volume factory option, which captures the block shape very closely.
