Fluid starting point I want to run a fluid simulation, but I want the fluid to start at some other frame than the start. 

How do I make the simulation start on a farther frame?
You could do this by adjusting the offset value of the fluid simulation.

Here's a short summary of this: 

Go to the offset settings of the Blender fluid domain (Assuming you are using Blender v2.81 or before), and adjust the value to a higher number to make the simulation happen earlier, and lower to happen later.

This will cause your fluid to show up later or earlier depending on the offset value. For a detailed answer to a similar question, look here.
