Hi,

I'm trying to figure out how to set the autodopnetwork to a simulation end time

For example, lets say I have 240 frames and I want the particle simulation to spray for 150 frames then end.

How can one accomplish this?

Greeting.
First select your autodopnetwork and then set the Start Frame parameter to whatever you want.

The Autodop is a little nontraditional as it doesn't go by frames, it seems to go by time scales. But I am not trying to prolong the start frame. I want the end frame to end earlier on a specific frame

I am assuming changing the start frame changes when it starts, but not when it finishes


Example timeline of 1 - 240 start on 1, and end on 150

So I don't understand why there is no end frame option

Sorry, I thought you wanted to start from specific frame!
There isn't option for end frame because it does't make sense!
You should specify how Houdini ends your simulation.
You can import your sim in a geometry node and then use a Time Shift node to end your imported sim on whatever frame you want.
Another way is to disable sources with a keyframe on specific frame.(if you have particle emission or FLIP or pyro sources for instance)

This is my Autodop, I have a flip solver if that is what you are refering to

I don't think saving it as a sim will work. Because I want the particles to fall off, after the emitter stops spraying

Example, lets say you turn on a faucet. Then you turn it off. The water still falls to the bottom, but it is no longer coming out the faucet

or maybe that is the velocity setting. I am not sure

Go to the Source Volume node and then disable Activation parameter with keyframe or expression.
See the HIP file.

Oh ya, that's pretty simple. Makes sense

Now it's working
