How to create a continuous Fluid Tank current?

Hello,

I am just beginning to really dive into Houdini more deeply, as I have only played around with it in the past really. I have been getting into the fluid simulations and dynamics area right now (still very much a beginner in this area), and I have been looking for tutorials on how to set up a fluid tank to have a continuous current. I have not found any unfortunately, only ones on objects moving into and out of a tank. So my question is:


How do I create a Fluid Tank that has a continuous current to move fluid particles past whatever collision geometry is placed within? (for testing like boat wakes, beach waves, etc. for example)


I have set the velocity in initial data to move in the X direction, and to kill particles at the opposite end but that just empties the tank since no particles are being created. It is probably right in front of my face but I have not found the area/node to tell it to birth more particles to create the
continuous flow. What am I missing? Is there a better route?

Thank you in advance to anyone who can help.

Have you tried adding an Emit Particles object to your setup? If your tank is emptying then you need to fill it. This will create a continuous flow.

Here is an example. After the tanks empties the in flow object keeps particles flowing in the X direction.

That's pretty sweet, Thanks Enivob! That is right down the route I am looking for. Ill rebuild myself just for learning's sake and then tweak to see what I can get out of that. Only question, was there a parameter that allows the particles from the box_in to grab the initial velocity of the tank's or is that just automatic from the source being fed into the flipsolver? Again, pretty cool. Thanks a lot.
