Reply To: DPM particles are colliding but not evaporating in combustion model

If you have or want film cooling model that, LWF should be sufficient. With that many steps it'll take ages to do an update, and you risk solver issues with anything that gets stuck. 

Thinking about the physics. With that many collisions the volume fraction must be fairly high near the injections. What does that do to the local flowfield? Have the particles actually moved far enough (and for long enough) to actually evaporate? Ie how old are the particles in your domain? 

No idea about the units. Fluent uses SI in the solver numerics so it'll depend on what you set the Units as for any imports: I'd generally recommend SI for everything to avoid confusion later on.
