row += 1 PLEASE HOW DO I SOLVE THIS ERROR

This has been fixed in MFiX 24.2.1. Please upgrade to the latest version.

please also the particle generator tool is missing from folder. I do i find it please. How do i generate spherical particles and other structures of particles with MFIX. Is there a section to select the shape of particle

If you select the “GSP” or “SQP” model in the Model setup pane,
shot-2024-07-25_09-05-38
shot-2024-07-25_09-06-11

then when you go into the Solids pane and add a phase, you will have the option to run either the Superquadric designer or Glued-sphere designer, which help you set up particle parameters:


Please can this be used for void fraction or porosity in packed bed. Because these methods don’t allow you to indicate void fraction of the particles

Void fraction is set in the “Initial conditions” pane
