Hello everybody,
I would like to conduct a multi-particle simulation using MPFEM (Multi-Particle Finite Element Method). I plan to utilize the LIGGGHTS software to create the particles. Once the particles are generated, I aim to extract data such as diameter and coordinates, and then import this data into LS_PrePost to carry out the remainder of the simulation. For the LIGGGHTS simulation, I want to consider a box as a die and a plate as a generator that is located above the box. The generator should pour the generated particles into the box.
I am purely a beginner in this software and I don't know how I should deal with it. Does anyone have an experience that can help me? or any tutorials?
Best regards,
Majid

Once, I did what you
Once, I did what you suggested for one of my simulations, but I don't know if the approach works for you or not. I created atoms using 'fix insert/pack' in my simulation, and then, using the following command:
dump dumpco all custom 1 coordinate/dump*.co x y z diameter
I extracted the coordinates of the particles at each timestep. The first timestep represented my desired positions of the particles before applying any forces.
