Hello, everyone,
I have been working on a simulation that involves the random compaction through uniaxial pressing of particles with varying size distributions, using two different material types to create a composite. Up to this point, the process and simulations have been straightforward, and LIGGGHTS has been an invaluable tool.
My next objective is to explore the possibility of “coating” particles of Type 1 with particles of Type 2, aiming to achieve a core-shell structure within the composite material. Specifically, I am looking into utilizing the multisphere approach for this purpose. However, my understanding is that the current multisphere implementations in LIGGGHTS are designed to support particles of the same material type, not for creating a composite structure with distinct core and shell materials.
Does anyone have experience or insights on how to achieve this kind of particle coating in LIGGGHTS? Is there a workaround or modification that can be applied to facilitate the simulation of a core-shell structure using different material types within the multisphere framework? Any suggestions, guidance, or references to similar work would be greatly appreciated. I am eager to learn if others have tackled similar challenges and how they approached them.
Thank you in advance for your time and assistance.
