Hello all, was hoping that you might be able to shed some light on a problem I've been having. For a particular model/problem I'm trying to solve, I want to be able to have a "large" droplet that will be shedding smaller droplets into the air, and I thought that twoPhaseEulerFoam would fit the bill. However, I am having an issue where, even more the droplet shedding processes can start, the initial droplet "explodes" into a strange characteristic pattern. For reference, I started with the "bubblecolumn" tutorial case, and simply modified the SetFields to leave a droplet in the center of the mesh. I have attached screen shots of paraView to illustrate what I'm running into. I would appreciate any insight that anyone could provide!

Thanks.
