How to add non-spherical particles

Hello,everyone!
Do you know how to add non-spherical particles to MFIX?
Thank you!

The current release of MFiX does not handle non-spherical particles. There will be a beta release soon of some new code that handles superquadric particles for DEM only. We will announce it here when it’s available, stay tuned!

Thank you for your help!@cgw
