Hi,

I'm fairly new to CFD, so I apologize if this is a silly question. I'm trying to simulate a water droplet falling into a water pool using interFoam. Most settings were copied from the damBreak tutorial example. The main question I have is that the droplet stretches and elongates in a funny way, instead of staying close to spherical. I've attached an archive of my setup. I'm assuming there is just something I've set wrong, but I haven't been able to find it.

Thanks for the help.

Tim

Here is a video of what's going on. It should be a drop of water, 2cm radius, falling into a pool of water. But for some reason the droplet stretches out instead of staying near spherical.

Any ideas about what could be going wrong would be greatly appreciated.

Thanks.
