How can I create the irregular thin-walled particles as shown in the figure in Edem? Are there any relevant tutorials that can guide me? Thank you.
Hi,
EDEM provides standard polyhedral particle shapes, as shown below, which can be created by specifying the dimensions in the respective coordinates. For particle shapes beyond these three standard options, a CAD model is required to represent the geometry accurately.
Irregular particle shapes can be model if you have an appropriate CAD and by importing CAD.

Thank you for your help. However, the templates imported through CAD can only be modeled using particle filling. I don't want this effect. What I want is that the particles themselves are not spherical, cube-shaped or conical, but the generated particles are directly in the form of thin sheets. How can this be achieved and are there any related tutorials available? thank you, applebigdog
Hi ,
Could you please share some reference images so that I can better understand the case and suggest the right approach?
hi， Sure, I will provide some actual material images as well as the models that others have created in the simulation software. Please check them out.
These are some photos of tobacco leaves. This paper uses EDEM to establish the complex shape of the particles and applies it to simulate the compression process of actual thin sheet particles. Thanks, bigdog
These are complex shapes and are nearly impossible to create accurately without CAD when using polyhedral particles. The only practical option I foresee is to approximate them using meta-particles. This can be done by creating tiny polyhedral particles, connecting them as meta-particles, and applying the linear elastic bond model to bond the individual meta-particles together. I hope this helps.
hi，
Thank you for your help. It has given me some inspiration.
Thanks，
