Hi Judy,

Thanks for getting back to me.

1) The initial temperature of the plate is 800K with the environment at 300K

2) I just have pressure outlets around the cube of fluid, I didn't assign any backflow temperatures.

3) The droplet temp is 300K as well.

4) I am using an inert water liquid droplet, an aluminum plate, and standard air all basic for ansys fluent, I will have to check for these values if they are critical. I will share a link to a youtube video of the first 1.8s of the simulation, you will see that this isn't an issue at all until this random iteration. 

5) The time step is 0.01s, as I am trying to run it for 5s. 

6) From the figures shown in the post, the continuity equations are always greater than 1, never converging under that. Then at the 8000 iteration it blows up.

7) I am getting backflow warnings at the outlet bc and temperature warnings at the localized cells, I included an image of this.

 

Here is the link to the video of the spray quench for the first 1.8s

Thank you,
