MFIX-PIC void fraction at close pack

Hi everyone, im having trubles with the void fraction of my simulations in a spouted with the model MFiX-PIC. Why i’m getting lowers void fraction if i initialized the case at the same fraction of void of close pack. Im using MFiX-19.3.1 in opensuse. This is my config file: solids.mfx (22.5 KB)

This are some screenshoots of my post process:

Thanks!
