Hi Everyone,

So I am performing an in-compressible combustion problem (steady state) in FLUENT. There are a few problems with my simulation.

1. So first of all, when I run my simulation, the continuity equation residual remains constant at around 1 or 0.1 and oscillates. The amplitude of oscillation changes with change in numerics, but still it oscillates around the same residual level.

2. I am not sure if I should use constant density or ideal gas for my simulation (I am using a pressure based solver)

3. When I add the droplets using DPM, due to addition of droplet source every 10 iteration, the continuous phase never comes to a steady state because of which the profile I get is completely wrong. How can this be avoided or solved?
