My previous case was operable. (The biomass particles were uniform.) But after changing the biomass particle size (five different particle diameters), now there are ghost particles. It is known that an error occurs as soon as the particles enter, and the temperature is -30K. I would like to ask where the problem lies. The solution I currently know is to forcibly initialize it to 300K, but I’m not sure if it’s accurate.

I added this condition, but it got stuck again after one minute. The version is 24.1.1.
xTs = MAX(xTs, 300d0)
Have you tried a newer MFiX version?
Thank you for your reply.I’ve tried, but it still won’t move. It’s stuck.
