Assistance Required: Restoring Superquadric Particles with "read_dump" Command

Submitted by blueguy on Mon, 03/25/2024 - 13:57

Hello,

I am currently facing challenges in resuming a simulation that involves superquadric particles formed by gravitational settling.

1. My initial approach was to utilize the "read_restart" command in a subsequent script file. Unfortunately, this method does not allow for resizing the simulation box with the "change_box" command.

2. My second attempt involved the "write_data" and "read_data" commands. However, I discovered that these commands do not support superquadric particles.

3. I then considered using the "read_dump" command to load a snapshot created by the "dump" command from a previous script as a potential solution. However, according to the online documentation available at https://www.cfdem.com/media/DEM/docu/read_dump.html, there seems to be no straightforward method to read superquadric particle data.

4. While I did find a potential solution on the forum (https://www.cfdem.com/forums/improvement-readdump-superquadric-properties), the link appears to be inaccessible.

5. If anyone has insights or solutions on how to restart a simulation with superquadric samples while also modifying the simulation box, I would greatly appreciate your guidance.

Best regards,
