Hi,

I've been trying to simulate a transient water droplets injection. I got the following error message, although I had defined a "Particle Mass Flow Rate" for the droplets at the injection points:

ERROR #001100279 has occurred in subroutine ErrAction.
Message:
The mass fraction of a particle has been specified in either a CEL expression or as an "Extra output variable". But no mass equation is solved for that particle type. Please change and re-run.

Does someone know what is missing to solve (or establish) a mass equation for the particles?

Thank you in advance.
