How to set particle size distribution in MPPIC

Dear MFIX Contributors,

It is known, in this forum, that for current version, it may have to set different solid phases with different particle diameters for the gas-solid fluidized bed with the bed material having a wider particle size distribution. Can you give us some suggestions on setting it to get a good result ? For example, how large the particle size interval should be divided?

best regards.

For the choosing of number of solid bins (or phases) to approximate the particle size distribution, you may need to do a sensitivity analysis study. For PIC, since it it very fast, you can use tens of bins to capture the full distribution. (While for DEM, I would use much less bins/phases to simplify the distribution).
