About particle input

Why does the file show the biomass particle input increasing over time, but the particle input process below is not visible in the VTK view?

I tried to input biomass pellets from the right side and bottom inlets, but I could not observe the biomass input process in VTK.

Biomass is injected at the bottom, but particles are injected below the inlet planes and it takes some time for them to travel up. The right inlet is not injecting any particles because the void fraction is 1.0. If you want to inject biomass, you need to set a non-zero solids fraction for phase 1. Setting a velocity is not sufficient.
