The result is diverging.
I generated a tet mesh of about 4mil elements and converted it to polyhedral.

Use a coarse mesh in the beginning. I don't know the size of your domain but prefer to run with maximum 0.3 - 0.5 million cells as first case. Once you are satisfied with the result, then refine the mesh using adaptive refinement only in the regions of liquid lumps.

Tried with 0.5 mil elements, still diverging

Then there is some issue with the setup of VoF-to-DPM. You have to follow the procedure to setup VoF-to-DPM as per the user guide.
