Error 1100: Solids phase 2 has a specified volumetric flow rate at BC 2, BC_VOLFLOW_S(2,2). But, both BC_ROP_s and BC_EP_s are zero or undefined

Hi, I would like to inject some particles into the fluid domain but failed.
I was wondering the mass flow rate and volume fraction of the gas and solid phase should follow a certain rule.
How i can control how many particles are injected to the domain?

If you specify a mass flow rate, then you must specify a non zero solids volume fraction, otherwise the inlet velocity cannot be computed.
