Dear friends!

I set a DPM problem aith combusting particles injection.

I turned on wet combustion and set liquid material to 0.4 of water.

and Then Laws: 1.Inert heating-2.evaporation-3.boilling-4.inert heating-5,6.Inactive

but for any time step, residuals have big oscillation. for example for continuity is between: 8e-1 and 5e-2 (I have species transport)

what should i do? if you have any question i'm here to give you more information such as my case and data files.

king regards masood
