Particles Evaporating while Advancing DPM Injection
 

Carbon particles are evaporating and I don't know why.
Injected particles are 144 nm in diameter.
Domain is 8 mm diameter 250 mm long.
Approx. 85000 elements.
Model includes stiff chemistry and therefore temperature is changing in the domain.
Wall temperature set to 1700 K.
Running steady state for volumetric phase and unsteady tracking for particles.
I increased vaporization temperature to maximum but particles are still evaporating.
