How to import an existing particle packing into EDEM as the initial packing configuration?

Hao Shi

Dear EDEM experts,

If we have an existing particle packing in a plain ASCII format:

Particle ID radius x y z vx vy vz omega_x omega_y omega_z

1…

2…

How can we import this as an initial packing in EDEM?

Regards,

Hao

Hi Hao,

You may have to write a Custom Factory as an API. You can read in data from a text file (which would be your positions) and then use the Factory API to generate this.

We have a couple of API examples that would be a starting point:

However if feasible you can use the Meta Particle functionality, although not directly designed for this it can work quite well for importing data from a text file, as shown in the video here:
