I have fluid simulation with an inflow object. I want the inflow to go for 2 seconds, then have the inflow stop (so no more fluid is added) but keep the simulation going (so the existing fluid sloshes around).

However, I do not see any way to set start and ending values on my inflow object.

How do I stop inflow at a certain frame/time in my simulation?

  1. Animate the Fluid's Enabled property:

    Fluid panel in Blender

  2. By right-clicking on it and Inserting Keyframes:

    Right click menu on Enabled checkbox

  • $\begingroup$ @leigero When you add an inflow object it is very obvious where it is. I added a picture for you :) $\endgroup$

scale down the inflow obj , or animate its position to make it get out of the domain when you need it stopped and bake ;)

    $\begingroup$ The correct answer has already been given, and this new "answer" is not good (while it may work, it comes with different problems that you don't get with the correct answer above). I can't see why it should be expanded. If anything, it should be deleted. $\endgroup$
