Okay, so in my 3D animated scene I will be including a puddle with a tap that drips. As its going to be pretty close up, I need to get the splash just right. Starting to get it happening I think. This is done with Mantaflow, the simulator included with Blender. I also have Flip Fluids, an add-on simulator that I purchased on Blendermarket. They work a bit differently, but time and experimentation will tell which is best for what I need.
